1) What are the technical properties of a table and explain about them?
Ans:- There are 7 types of tech. properties .They are
a) Delivery Class: - It is used to control the Transport of the table data.
It is used to specify the type of the table.
 In Real time we mostly use the delivery class 'C'.
 In case of delivery class 'A' the table can maintained in any system (development, quality,
production systems) using SM30.
b) Data Browser/table view maintenance: - This property is used to specify the whether the
table can be maintained or not.
 In real time we mostly use “Display/maintenance allowed “option.
c) Data Class:- It is used to specify the type of the data to be maintained in the table.
 In Real time we mostly use APPL0 or APPL1.
 APPL0 – Master data – Access frequently & updated (changed) rarely. Ex: D.O.B
 APPL1 – Transactional data – Access frequently & updated frequently. Ex: Sal
 Organization & Customizing data – Updated rarely. Ex: Company Codes
d) Size Category: - It is used to specify the initial space required for the table in the data base.
 In real time we mostly use '0' category. ( 0 – 7 ) -> [ 0 – 7100]
e) Buffering: - It is used to control (reduce) the traffic in the data base when the table accessed
by the multiple users.
 In Real time we mostly use the mode “Buffering not allowed " – Table Can’t be buffered
 Buffering allowed but Switched Off – Buffering allowed but not activated
 Buffering Switched on – The table can be buffered. In case of this option any one of the
buffering types should be selected.
 Single record buffering: In case of this buffering type, record by record is buffered
from the database tables.
 Generic Area buffer: It is used to buffer the table data based on the specified key
fields. In case of this buffering type, the no. of key fields must be specified.
 Fully buffer: The entire table is buffered.
f) Enhancement category: - It is used to enhance the particular fields of the table.
 In Real time we mostly use “Can be enhanced (DEEP)”.

g) Table Maintenance generator: - It is used to maintain multiple entries & validate the table data
using the T-code SM30.
2) What is the purpose of Table Maintenance Generator (TMG)?

Ans: - It is used to maintain (Change, create, modify) the custom tables using the standard T-Code
SM30 & the T-code SE54 is used to create TMG.
3) What are the events in TMG?

Open SQL: It is a set of statements which can interact with any kind of database.
Native SQL: It is specific to the particular database & it hits the database directly.
Q) How data is stored in cluster table?

Ans: A cluster table contains data from multiple DDIC tables. It stores data as a name value pair

( varkey, vardata)

6) Is it possible to create custom transaction code to maintain the table? If yes, how to create it?

Ans: - Yes, We can create by using the custom T-Code using SE93.
7) What are the differences between Include structure and Append structure?

.INCLUDE Structure .APPEND Structure

5. It is possible to add the additional fields 5. It is not possible to add the additional fields
manually after Include statement. manually after Include statement

8) How to identify the standard tables? (Indications)

Ans:- 1) The tables which doesn't start with Z or Y.

2) The tables which can't be seen in the CHANGE mode.

9) How to see the relationship between the tables?

Ans:- 1) Using SQVI T-Code.

2) While maintain data in the child table (Foreign key relationship).
10) How many types of Indexes are there and explain about them?

Ans:- Indexes are used to avoid the duplicate data while accessing the table. Indexes can also be
used for better performance while extracting the data from the tables. There are 2 types of
Indexes.
1) Primary index: It is generated by the system using the key field of the tables.
Key fields hold the unique data.
2) Secondary Index: These are created and maintained by the Technical Consultants/ABAPer.
We can create 9 secondary indexes per table. We can create the secondary indexes for both
custom & standard tables.
Q) What is Where Used List?

Ans: It is used to list out all the dependent objects & know the usage of the particular object.

 The T-code SQVI is used to check the relationships between the tables.
Q) Can we add/Enhance additional customer specific field vales to standard domains?

Ans: Yes, the standard domains can be enhanced to add, additional customer specific fixed values
& intervals using the Menu path: Go to -> Fixed Value Append at Domain level.

11) What are the differences between Check table and Value table?

Check table Value table

1. It is maintained at the TABLE level. 1. It is maintained at the DOMAIN level.
2. It can be used to extract the data in the 2. It can't be used to extract data since it is linked
programs. with the domain.

3. The Search Help is displayed from the

Check
table on the foreign key field of a foreign 3. The Search Help is displayed on each field
key which is linked with the same domain of the
table. Value table.

4. It forces the user to select any one of the 4. It does not force the user since it has empty
check table field entries value by default.

12) What are the types of Views and explain about them?

Ans: - Views are the virtual/imaginary tables. It does not contain the data permanently.
View contains the data at Run time only.
1) Database View: - It is used to combine the multiple tabled data by joining them. It can be
used to extract the data in the programs.
2) Maintenance View: - It is used to maintain multiple tables data using the T-code SM30 (TMG).
3) Help View: - It is used in the selection method in an Elementary Search Help to provide the
list of possible entries from the multiple tables.
4) Projection View: - It is used to HIDE the unwanted fields of the table. It can be
defined using one table only.

13) What are the Search Help, types and explain about them?

Ans: - It is used to provide all the possible entries to the input variable as search help.
1) Elementary Search help: - It is created using one base table.
2) Collective Search help: - It is the collection of Elementary Search help.
Search Help Exit: It is a Function module to filter possible entries of a search help.
It is used to modify the F4 values at run time.
14) Is it possible to create a table/structure without creating any data element and domains?

Ans:- Yes , we can create using the predefined types.

It is used to create the table without using Data Elements/Domains.
 If the table or structure is created using predefined types, the symbol ' + ' is appeared
instead of field labels while maintaining the tables.
 Reusability is not possible with the Predefined Types.
15) What are the Lock objects and explain about the different lock modes?
Ans:- They are used to control the parallel access for the same data by the multiple users. It avoids
the concurrency access of multiple users on the same Database.
 The custom lock object name should start with 'E' followed by the table name.
Ex: - E < ZB16_Student >.
 It generates two function modules one start with ENQUEQE and other start with
DEQUEQE.
 ENQUEQE - Request for Lock
 DEQUEQE -To Release the Lock

Types of Locks:
1) Write/Exclusive: The locked data can be accessed by single user only. All other Lock
requests are rejected.
2) Read/Shared: The multiple users can access the same data at the same time. If no user
tries to edit the data, all other users cannot access this data.
3) Exclusive but not Cumulative: It can be requested only once by the given transaction
Codes. All other lock requests are rejected.
SM12 : This T-code is used to list out the locked objects & to delete the locked objects.

16) What are the difference between Table and Structure?

Table Structure
1.Table contains the data 1. Structure does not contain the data. It is
filled with single record at Run time.
2. It must contains at least 1 field as 2. It does not contain primary fields.
Primary Fields.
3.Database must contains Delivery class & 3.It does not contains Delivery class &
Technical settings. Technical settings.

17) Explain about Data element & Domain.

Ans:- Data Element :- It is one of the data dictionary object which can be used to maintain the
field labels (descriptions) of the fields in the table or structure.
 Parameter ID’s are maintained at Data Element level under Further
Characteristics tab.
Domain: - It is one of the data dictionary object which can be used to maintain the
technical properties of the fields in the table such are Data types (char,
numc....etc), length of the data (10, 20...etc)
 It can be used to maintain Value table to provide search help on the field.
 Conversion Routines are maintained at Domain Level.
18) How to adjust the table/View?

Ans :- If there was any changes made at the table level the system will throw an error as
‘Structure change at field level '. The table must be adjusted to rectify this error.
 The T-Code SE14 or the path: Utilities --->data base objects ---> data base utility can be
used to adjust the table.
 If the key field is changed as non-key field then the system throws an error ‘Convert
Table’: structure changed at Table level.

Q) I have a Z-Table, I wants to add one more field to the table without disturbing previous data, what
should I do?

Ans: While adjusting database table in SE14, select 'Save Data' radio button.

19) What are the different ways to provide search helps?

Ans:- We can provide in 3 ways .

 Using value table at Domain level.
 Foreign key relationship.
 Elementary and collective search help.

20) What is type group and explain?

Ans :- It is one of the data dictionary objects.

 It is used to define the Global types, Internal tables and constants which can be referred
anywhere in the system.
 The ABAP statement TYPE-POOLS is used to call/define the type group.
21) What is table type and explain?

Ans: It is one of the data dictionary object used to define the global internal table which can be
referred across the system.

22) What is the Maximum No. of structures that can be included in a table or Structure?

Ans :- 9 ( Nine )

23) Can you use all the Views in the ABAP Program?

Ans :- No . We can use only Projection view or Database view in the Program.

24) In which table are the programs, Tables, Development classes are sorted in?

Ans:- The Programs details are stored in the table TADIR, Data base tables in DD02L and DD02T and
the development class packages in TDEVC.

25) Explain about the tables TADIR and TRDIR?

Ans: TADIR is a table which holds the Data Dictionary objects. i.e; Data elements, Domains, Tables
& TRDIR stores all the Programs details.
26) When you create new entries in the table the field values are always in Uppercase. How do you
get the data with mixed case? (OR) How to make a table field to store a lowercase value?

Ans :- The reason for this is that the Domain for the Field in the table might have Lowercase
checkbox unchecked. Check the LOWERCASE CHECKBOX to preserve the case of your data.

 The checkbox Lower case is checked to make character fields as a case sensitive to accept
both Upper & Lower case letters. Since the system takes the ‘Character’ data type as Upper
case letters by default.
 Also, we can determine whether a field stores lower case value or not by checking the
“Lower Case” check box of its domain. If this is checked then it will store both lower case
and upper case. If it is not checked then it will store only upper case values.

Steps:

1. Create a demo table say ZDEMO_TABLE.

2. Generate Table Maintenance for this.

3. Now create new entries with the help of transaction SM30.

4. Click on New entries.

5. Enter value and save.

6. Data will be saved in the capital letters or check entries using transaction SE16.

7. Now we want to store the entries in lowercase. Here are the steps to achieve this.
a. Go to the domain of the field to which you want to store values in lowercase.
b. Click on Change/display button.

c. Check the lower Case check box.

d. Save and activate the domain.

e. Now again create new entries with the help t-code SM30. Enter values and save.
Output:

Values will be stored in the given case.

27) What is Transaction code?

Ans: They are the commands/shortcuts to execute corresponding application. In SAP

each screen is associated with T-Code.

a) Standard T code: They are the system provided to work with the pre-defined applications. The

Standard T-codes could only be the combination of any alphabets/alpha-numeric

Ex: SQVI, SE11, SE38 (SE-System Engineering, SM – System Machine, SQ-System query)

b) Custom T code: They are created & maintained by ABAP Technical Consultant

SE93 is used to work with custom T-code.

 TSTC – It is the standard table which contains all the Transaction Codes in the system.
 TFDIR – Function Modules
28) What is Data Dictionary/DDIC?

It also sends back the services to the presentation layer. There are 4
types of components in application layer.

a. Dispatcher: It is a link between the presentation layer & the work process. It receives
the request from the presentation layer & sends them to an appropriate work process
to get them processed.
b. Gateway/Layer: It is a communication protocol of the cross application components
such are $, BAPI etc. It provides link between two SAP systems.
c. Shared Memory: It is a common memory which can be shared by all the work process.

objects.
35) What is Foreign Key?

Ans: A key field is defined as a table field & is primary key of another table is called foreign key.

 The Check table field should be a primary key.

 The Domain name of the Check table & foreign key table should be same but field name is
different.
 A search help is displayed to see the possible entries of a check table on the foreign key field
when the foreign key table is executed.

36) What is a Client Dependent & Client Independent table?

Ans: The table which have the field MANDT field (Client no) is called Client Dependent table.

The table which don’t have the MANDT field (Client no) is called Client Independent table.

37) What are Key field & Non-key fields?

Ans: The key fields don’t allow duplicates. It contains unique data. The key field check boxes are
checked to make the fields as primary key.

 The non-key fields may/mayn’t allow duplicates. The key field check boxes are unchecked.

38) What is Initial Value Check box?

Ans: The Initial Value Check box is checked to take the default field values of the key fields for the
1st time.

39) Differences between the tables created using Data elements & Pre-defined types?

41) Explain about Currency or Quantity fields in DDIC?

Ans:

 In SAP the currency & quantity fields are required currency key & quantity unit. Hence, the
reference table & the reference field must be specified for currency & quantity fields.
 The data type for the currency field is ‘CURR’ & the data type for the currency key is ‘CUKY’.
 The data type for the quantity field is ‘QUAN’ & the data type for the quantity key is ‘QUAN’.
 The reference table could be any table which has the currency key & quantity unit fields.
 The same table can also be used as a reference table if it has the currency key or quantity
unit fields

Q) What is table buffer? Which type of tables used this buffer?

Ans: Buffer is nothing but a memory area. Table is buffered means that table information is
available on application server. When you call data from database table it will come from
application server. Transparent tables and pool tables are buffered, while cluster table
cannot be buffered.

Work Area Internal Tables

1. It Holds single record at a time. 1. Holds Multiple records.
2. It doesn't have BODY. 2. It has BODY [].
3.The Record by record is 3. In case of internal table with header line the record by
processed through the work area record is processed through header line.

Q) What is difference between Internal Table without Header Line and Internal Table with Header
Line?

Ans: Internal Table without Header Line creates an internal table and work area separately. When
the Internal Table with header table is created then the work area is created automatically with the
same name that of the internal table.

10). Explain about Types.

Ans :- TYPES :- It is used to club the multiple fields from the multiple tables as a single unit . It is

used as a reference to declare the Data variables, Work areas, Internal tables etc.
DATA: It is used to declare the data variables such as variables, work areas, internal
tables etc in an application program.
Syntax: - TYPES: BEGIN OF <typ_dbtab1_dbtab2>,
<F1> TYPE <data element1/dbtab1-F1/dbstr_F1>,
.
<F5> TYPE <data element5/dbtab1-F5/dbstr_F5>,

DATA: <gs-dbtab1_dbtab2> TYPE <typ-dbtab1_dbtab2>. //declare the work area
11) What are the different ways to declare the Internal Table and which is preferable?

Ans :-There are two ways to declare the Internal tables.

1) Syntax:-
DATA: <gt_dbtab> TYPE STANDARD TABLE OF <dbtab/dbstr.....>. //Preferable.
2) Syntax:-
DATA: <gt_dbtab> TYPE TABLE OF <typ_dbtab /dbtab/dbstr> WITH HEARDER LINE.
12) What are the differences between PARAMETERS and SELECT-OPTIONS?

PARAMETERS SELECT-OPTIONS
1. It is used to define Check boxes, Radio buttons & single 1. It is used to define Single & Range
I/P fields. input Fields.

Data types 2. The ABAP statement FOR is used.
3. The operator 'IN' is used in the
3. The Operator 'EQ' or '=' is used in the WHERE condition. WHERE condition.
4. It is system generated internal
table with the fields SIGN, OPTION,
4. It is use as an input data variable HIGH & LOW
13) What are the different types of internal tables and explain about them?

Ans :- Internal Tables: - They are the intermediate tables to hold the multiple records at run time.
 There are 3 types of internal tables.
1. STANDARD Internal tables: - The standard Internal Tables are filled using the
ABAP statement 'APPEND'/’INSERT’. It accepts the duplicate records. Searching
of a record is Linear Search. It is the default index table. Standard internal table
can be sorted explicitly.
Syntax: - DATA: <gt_dbtab> TYPE STANDARD TABLE OF <typ_dbtab/dbstr.....>.

2. SORTED Internal table: - The ABAP statement 'INSERT/APPEND' is used to fill

Sorted Internal Table. It does not accept the Duplicate records. Searching of a
record is Binary Search. Sorted internal table cannot be sorted explicitly. An
additional statement with UNIQUE/NON-UNIQ UE key must be used to declare
Sorted Internal Tables.
Syntax :- DATA: <gt_dbtab> TYPE SORTED TABLE OF <dbtab/dbstr.....> WITH
UNIQUE/NON-UNIQUE KEY <k-f1> <k-f2>.
3. HASHED Internal tables: - They are Non Index tables. The Hashed Internal Tables holds huge
amount of data than Standard & Sorted internal tables since they follow ‘Hashed Algorithm’.
The ABAP statement ‘WITH UNIQUE KEY' must be used to declare Hashed Internal Tables.
It holds huge amount of data (2 GB) than standard & sorted internal tables.
Syntax:- DATA: <gt_dbtab> TYPE HASHED TABLE OF <dbtab/dbstr.....> WITH
UNIQUE KEY <k-f1> <k-f2>.
Q) Can we sort internal table without using SORT statement. Explain?

Ans: We can sort internal table without using SORT statement by declaring sorted internal table . Ex:
DATA: IT_MARA TYPE SORTED TABLE OF MARA.

14) How to define SELECT-OPTIONS without specifying the table name?

Ans :- By declaring a Global Variable and use it as a reference while defining a select option
instead of TABLES statement .
TABLES: This statement is used to specify the database tables/database structure names
Which can be used as a reference while declaring the SELECT-OPTIONS
 This statement in not advisable since it creates unnecessary work areas.
15) Explain few of the additions to PARAMTERS and SELECT-OPTIONS statements.

Ans :- Obligatory: It is the keyword to make the input field as mandatory

Default: It is the keyword to pass the default values to the input fields.

As checkbox: It is the keyword to define the checkboxes in the selection screen

Radio button group: It is the keyword to define the radio buttons in the selection screen

As list box: It is used to define the dropdown list in the selection screen

MATCHCODE OBJECT: It is used to specify DDIC search help to the input fields

MODIFID: It is used to assign all the screen elements to the modification group to format the

Selection fields dynamically

LOWER CASE: It is used to make the input fields as case sensitive to accept both upper &

Lower case letters

Memory ID: It is the keyword to access the field value from one session to another session

Additions of SELECT-OPTIONS

a) NO-EXTENSIONS: This addition is used to hide the multiple selection button in the
Selection screen.

b) NO-INTERVALS: This addition is used to hide the higher limit of select-options in the

Selection screen.

c) DEFAULT…TO: This addition is used to pass the default values to lower & upper limits

16). Differences between Ranges & SELECT-OPTIONS?

Ans: It is used to define range internal tables. It is similar to SELECT-OPTIONS.

 SELECT-OPTIONS are displayed in selection screen where as Ranges doesn’t appear in the
selection screen.

Q) What is the Size of the internal tables?

Ans :- Internal Tables have 2GB (Giga bytes) of memory space and the initialize size is of 8 kb which
can be extend further.

17) Explain Some Additions to Report statement?

Ans: 1.No standard page heading: This addition is used to hide the page heading in the output.

2. Line size: This addition is used to specify the width of a list in the output.

3. Line count: This addition is used to specify the length of the output list in a page.

4. Message ID: This addition is used to specify the message class

Q) Some Keywords?

It also used like an APPEND statement. This statement is used to compare character/string
fields data & summarizes the numeric field data. It is used to display sub-totals .
Syntax : COLLECT <gs_source> INTO <gs_collect>.
Lines:
It is the keyword which returns no of records available in the internal table.
Occurs:
It is the keyword; it allocates 8KB of memory for the internal table by default. If the data in the
Internal table exceeds 8KB then it will bring one more 8KB of memory & so on up to 2GB.
Clear: It clears the contents of the work area & internal table with header line ITAB[ ] & variables
Refresh: It clears the contents of the internal table only.
Free: It clears the contents of internal table along with allocated memory.

24) What are the differences between Normal Search (SELECT…ENDSELECT) and Pointer Search
(INTO TABLE)?
Ans :-
Normal Search(SELECT…..ENDSELECT) Pointer Search(INTO Table)
1. It hits the data base table for each record since it 1. It hits the data base table once to extract
is a loop statement all the required data since it is a statement
2.The ABAP statement 'APPEND' must be used to
append record by record into an internal table 2. No need to use 'APPEND'
3.Some times it may give runtime error while
debugging 3.It doesn’t give any short dumps
4.Not advisable due to lack of performance & data 4. It is advisable since it extracts the data
base load faster & has good performance

25) What is the difference between SY-INDEX and SY-TABIX?

Ans:

 SY-TABIX: SY-TABIX is a system variable which stores the index current processing record
of an internal table. So when you are looping over an internal table, you use SY-TABIX.

LOOP AT ITAB INTO WA. **SY-TABIX stores index number of internal table record ENDLOOP.

 SY-INDEX: SY-INDEX is a system variable which acts as a loop iteration counter, it stores
loop iteration number. When you use DO ENDDO / WHILE for looping, there is no table
involved. So you use SY-INDEX.

Ex: DO 10 times. **SY-INDEX stores number of iteration of loop ENDDO.

Modularization Techniques

Modularization Techniques
1) What are the Modularization techniques which you follow?

Ans :- They are used to organize the ABAP code in the proper way , make the program more
Understandable and make use of the code re-usable to avoid the duplicate data.
To divide the business processing logic into reusable block of statements.
 Following are the different types of Modularization techniques
o INCLUDES: These programs are part of another main/include programs. Include
programs can’t be executed independently whereas the same include program can be
included in any no of executable programs. The ABAP statement INCLUDE is used to
call or define the INCLUDE programs.
o Subroutines: These are statements local modularization techniques. The sub-routines
can be debugged at run time. Calling should be 1st & Definition should be next. The
ABAP statement PERFORM is used to call the sub-routines & FORM…ENDFORM is
used to define the sub-routines.
There are 2 types of sub-routines.
I. Internal Subroutine: These are defined & called in the same program.
II. External Subroutine: These are defined in one program & called in another
program.
Actual Parameters: The parameters which can be called while calling the
subroutines (with PERFORM statement).
Formal Parameters: The parameters which can be passed while defining the
subroutine (with FORM statement).
 The no of actual parameters should be similar to the no of formal parameters.
 The sub-routines definitions should not be nested (form with in the form) but the
sub-routine can be called within the sub-routine.
 The statements between 2 sub-routines definitions cannot be accessed

o Macros: These are used for the complex write statements & for long calculations.
Macros can take up to 9 place holders (&1…. &9). In macros Definition should be 1st &
Calling should be next. The ABAP statement, DEFINE…END-DEFINTION is used to
define a macro. The macro definitions cannot be debugged at run time. The standard
table TRMAC pooled table is used to maintain macros.
o Function Modules: These are global modularization objects. The function modules
can be called any where in the same system & in another system also. The function
modules are defined in function builder.

The T-code SE37 is used to work with the function modules & SE80 is used to work
with the function group. The function modules should be assigned to a function group
& Function group is the collection of function modules.
 The standard table ‘TFDIR’ is used to find FMs since it contains the entire
Function module in the system.
  Normal Function Module: These are defined & called in the same system to
reuse the central source code.
 Remote Function Module: These are defined in one system & can be called
another system.
 Update Function Module: This is used for SAP LUW (Logic Unit of Work). These
function modules are triggered in case of implicit or explicit COMMIT work is
encountered. Commit Work is used to make changes in data base permanently.
o Message class: This tool is used to maintain the Messages in the message pool.
They are used to give messages for instructing the users.
The standard T-Code SE91 is used to work with the message pool.
Different types of messages are Error, Success, Warning, Information, Abort, Exit.

o Text symbols & Constants: The ABAP Statement TEXT followed by the symbol
number (XXX) can used to define or call the text symbol. Constants are used to avoid
the hard coded text and improve the reuse them in the program.
The T-code SE63 is used to translate the different types of text elements.

2) What are the differences between Subroutines and Function Modules?

Subroutines Function modules

1. These are local. We can access the 1. These are global. We can access the
Subroutine within the server only. function module with in server as well as
Outside the server.
2. We can’t execute the subroutine 2. we can execute function module
independently independently using the T-code SE37

3. Subroutines can’t handle the Exceptions. 3. Function module can handle the errors
through Exceptions.

3) What are the differences between Macro & subroutine?

Macro Subroutine
1. Definition & calling in the same program. 1. Definition & calling may/may not in the same
Program.
2. Definition should be the 1st & calling should be 2. Calling should be the 1st & Definition should
The next. Be the next.
3. Macros can take up to 9 inputs. 3. Subroutines can take any no of inputs.
4. Sub-routines can be debugged at run time. 4. Macros cannot be debugged.

4) What are the different parameters in Function Modules and Explain about them?

Ans: Following are the different types of Parameters in Function Modules

  Attributes:
It contains technical properties of a function module such are type of function
module, function group.
 Import parameters :
They are imported from the calling program to the function module.
 Export parameters:
These are used to exported the data from the function module to the calling
programs.

 Changing parameters:
These are imported from the calling program, changed them in the function
modules & exported/returned to the calling program. (Import -> Change -> Export)
 Tables:
These can be used to import & export only for internal tables.
 Exceptions:
They are used to raise/handle the messages in the function module based on
return code (SY-SUBRC).
 Source code: It is used to write central ABAP source code.

5) Explain about different methods to pass the parameters to sub routines?

Method Description Effect
It is the default method. The pointer used the same memory
BY allocation for both actual & formal parameters. From calling to The Actual parameters
Refere definition & definition to calling, all parameter values are passing are changed with the
nce along with the memory. Formal parameters.
The system allocates new memory. The allocated memory is freed The Actual parameters
By once the subroutine ends. From calling to definition & definition to are not changed with
Value calling, the parameter values only passing. the Formal parameters.
By
Value The Actual parameters
and It is almost similar to By value but only the difference is the Formal are change with the
Return parameter values are returned to Actual parameters. Formal parameters.
 DEBUGGER

Debugger

1) Explain about Debugger, Break points and Watch points?

Ans :- Debugger :- This tool is used to check the program line by line & block by block for finding
and rectifying errors or bugs.
Break Points:- These are Statement based. They are used to stop the program in the
debugger tool for checking line by line or block by block.
 Break points are of 4 types. We can place up to 30 break points in the program.
1. Session Break Point: An icon set/delete breakpoint icon or click on statement line at
gray color vertical selection in the source code.
2. Static Break Point: The ABAP statement BREAK-POINT/BREAK <user_name> is used
to set the Static break point. In the real time the ABAP statement BREAK-POINT
should not be used since all the users are stopped.
3. Dynamic Break Point: They are used to check the program in case of not possible to
find a location. The command /H is used to set dynamic break points. The program is
stopped at the first statement line of the performed action.
4. External Break Point: They are used to check the cross application components such
as RFC, BAPI from one system to another. An icon set or delete external break-points
is used to set or delete external break-points.
Watch Points: - These are Condition based. They are used to stop the program once the set
condition is reached. The Watch points can be set inside the debugger tool. We can place up to
9 watch points in the program. We can reduce debugging time using watch points.

2) Differences between Classical & New debugger?

Ans:
Classical debugger New debugger
1.It is the old debugger 1.It is introduced from the version ECC 5.0
2.It runs on the same session to check & resolve 2.It runs on the separate session
the issues in the program
3. It has Lots of limitations such as different 3.It is very efficient tool to check lots of actions
desktops are not there, no separate sections for such as different desktops, separate actions for
local , global Variables etc local & global Variables & objects at a time

Single Step F5: The function key F5 is used to check Line By Line of the program.
Execute F6: The function key F6 is used to check Block By Block of the program.
Return F7: The function key F7 is used to Return from the source code of the process blocks such
as sub-routines, function modules, methods etc.
Continue F8: The function key F8 is used to jump from one break point into the next break point
then execute once the last break point is reached & then execute.

3) How to debug Background Jobs?

5) What are the types of execution modes?

Ans: There are 2 types of execution mode to execute a program or the transaction codes.

1. Foreground: It is used to execute the programs or the transaction codes directly by pressing
execute icon or F8 function key. It requires user interaction.

2. Background: This execution mode is used to execute the programs or the transaction codes
periodically such as Hourly, Daily, Weekly, Monthly etc in background. It doesn’t
require any user interaction. The variants must be created before the programs are
scheduled in back ground.

 The T-code SM36 is used to define the background jobs &

 The T-code SM37 is used to check the status of the background jobs.

The standard function modules JOB_OPEN -> To open back ground job

JOB_SUBMIT -> To submit job in back ground

JOB_CLOSE -> To close scheduled job.

* List of PARAMETERS

SELECTION-SCREEN END OF LINE.

36) How to place the PUSH buttons (Function keys) on Selection Screens?

Ans:- Requirement:

Three buttons display, change, create to be created along with their respective icons on the selection screen.

Steps to be followed:

Step1: Create program in SE38 with some meaningful description.

Step2: Create a selection screen with two or three fields.

Write the below code in the program after the above selection screen statement.

Write the below code in the program in the Initialization event.

Execute the report and you will see three push buttons on the selection screen as below.
Now to handle the buttons in the program, first we need to create a custom GUI status copied from the
standard GUI as below

RSSYSTDB& %_00 refer to the standard GUI status.

Now we need to add the function codes for the above three buttons created on the selection screen.

FC01, FC02 and FC03 refer to the three buttons which we have activated above.

Here we will add the function codes for the three buttons. These function codes will be captured in the system
variable SY-UCOMM field and this can be used in the program logic.

Function code ‘DISP’ is used here for the first push button (FC01), similarly ‘CHAN’ and ‘CREA’ for second
and third push buttons respectively.
After entering the function codes for all the push buttons active the pf-status.

Now come back to the program and write the below code in the

AT SELECTION SCREEN OUTPUT event.

Now execute the program and you can find the below selection screen.

Summary: In this way we create buttons along with the icons on the selection screen.

Ans :- The below events are used in the MPP.

1. PROCESS BEFORE OUTPUT (PBO):

 This event is triggered before the screen is displayed.

 It can also be triggered while performing any action on the screen.
 This is used to provide the default values to the screen fields.
 It can also be used to format the screen elements dynamically.
2. PROCESS AFTER INPUT (PAI):

 This event is triggered after the Input values are provided to the screen.
 This event is used to validate the input data on the screens.
 It can also be used to process the screen data based on the performed action
(pressed push button menu item etc)
3. PROCESS ON HELP-REQUEST (POH):

 This event is triggered when the function key F1 or help icon (?) is pressed.
 This event is used to provide the help documentation on the screen fields.
 The T-code: SE61/SO72 is used to maintain help documentation.
 The standard function module ‘HELP_OBJECT_SHOW’ is used to display the maintain
help documentation.

4. PROCESS ON VALUE-REQUEST (POV):

 This event is triggered in case of in case of function key F4 or search help icon is
pressed.
 This event is used to populate & display the custom search help on screen input
fields.

8) What are the different ways to execute the Screens?
Ans :- There are 2 ways to execute the screens.
1. Using the T code: The screens can be executed through the T codes to which the
Module pool program & the screen no is assigned.
2. Using an Executable program: The screens can be called & defined using the
Statement ‘CALL SCREEN’. CALL SCREEN is used to call the specified screen
number.
9) How to validate/check the fields (screen) in Module Pool program?

Ans: - a) Use an event Process After Input to validate the Input//screen field values.
b) Once the Flow logic is in Change mode, define the module with the field statement between
CHAIN…ENDCHAIN screen statement.
C) Fetch the data from the database & give the proper message if data doesn’t exist.
 The statement CHAIN….ENDCHAIN is sued to make all the screen input fields enables to
enter input data.
 The screen validations without CHAIN….ENDCHAIN statements make the screen input fields
grayed out (display mode).
10) How to make screen field as mandatory in Screen painter?

SAP Scripts
 SAP SCRIPTS

1) What are the Components of SAP Script (Form Painter/Layout set)?

Ans: SAP Script form contains 2 parts.
1. Form painter (Layout Set) 2. Print Program
1. Header: It is used to maintain the Administrative & basic settings data.
a. Administrative data:
 It contains the technical details such are Package name, Changed by, Created by etc..
b. Basic data:
 It is used to maintain the default settings which can be applied across the forms.
 The Basic settings are page format, orientation, font size etc.
 The first page & the default paragraph names must be specified once they are created.

2. Pages:
 They are the rectangular format of the documents.
 This element is used to maintain the next page, print mode, page counter mode etc.
3. Windows:
 They are the small components on the pages.
 We can place the same window in any no of pages.
 The windows are not positioned on the pages unless they are assigned to the pages.
4. Page window:
 They are used to position the window on the pages.
 Different position attributes Left margin, upper margin, Window width, Height are
maintained. It is used to place the window on the page with co-ordinates.
5. Paragraph format:
 They are used to print/format the entire paragraph with a required format & style.
a. Standard Attributes: It is used to maintain the standard attributes such are alignment,
line spacing, left margin, right margin etc.
b. Font Attributes: They are used to maintain the font setting such are font family, font

process the extracted data & pass the processed data to SAP Script form to
display/print on the document.
2) What are the difference types of Windows?

Ans: Windows: - They are used to define the different types of windows.
 Following are the different types of windows.
 Main Window: It is the default widow. It is used to display the continuous text on
the pages. Without main window we can’t design SAP scripts. The system
generates the pages dynamically for main window. Up to 99 main windows can be
created in a form. The window type is ‘MAIN’.
 Constant Window: This window contains the static content which can be
formatted only once to print/display the same contents on all the pages.
 Variable Window: It is used to print the data based on the window size. It can be
formatted for each page to print/display the different contents. Without a variable
window also we can design the SAP script.
 Graphic Window: It is used to print/display the graphics/logos on the page.
3) What are the different types of Symbols in Scripts?
Ans: - The Symbols are the constants which can be inserted n the page windows to display/print the
corresponding contents/data. Symbols are of 3 Types.
1. System Symbols: They are used to display the system data such as date, time etc …
Ex: &DATE&, &DAY&, &MONTH&
Symbol Description
&DATE& System Date
&DAY& Day of the System
&MONTH& Month of the System
&YEAR& Year of the system
&TIME& System Time
&HOURS& System Hours (HH)
&ULINE& Horizontal Line

 The system provided standard structure SAPSCRIPT contains some of the SAP Script
system fields.

Note: Number of pages like “1 of 10” can be displayed using the system symbols PAGE &
FORM PAGE as below.

Ex: &PAGE& of &SAP SCRIPT-FORM PAGES&

Current Page number, Total no of pages

2. Standard Symbols: They are the predefined symbols. The pooled table TTDTG is used to
maintain the standard symbols.

3. Application Symbols: These are used to display/print the processed data from the print
program or database. Ex: &WA_T001-BUKRS&
4) What are the different TAG columns in SAP Script form?

Ans: Tag Meaning

* Default paragraph format

= Extended Line

/: Command Line

/* Comment Line

/E Text Element -> Display multiple entries of an internal table

P Paragraph format

/= Line feed & Extended line

5) What are the Function Modules associated with Scripts?

Ans:-The below Function Modules are used in the Scripts.

1. OPEN_FORM: (*)
 This function module is used to provide the link between the print
program & SAP script form.
 The global data variables of the print program can be accessed in SAP Script form
after this function module is called to open a form/used.
2. START_FORM:

 This function module is used to specify the starting page from where the
document to be printed or displayed.
3. WRITE_FORM: (*)

 This function module is used to pass the multiple entries of an internal

table into the SAP Script form to print/display the multiple entries or
line items through the Text Elements.
4. END_FORM:

 It is an optional function module which is used to End the started Form.

5. CLOSE_FORM: (*)

 This function module is used to close the Opened Form & send the
Spool Request/Print to the device.
 It can also be used to get the SAP Script form data into OTF (Other Text) format.
Note: The standard function module ‘CONVERT_OTF’ or ‘CONVERT_OTF_2_PDF’ can
be used to convert the SAP Script OTF Data into PDF format.
 The standard function module SO_NEW_DOCUMENT_ATT_SEND_API1 is used to
send an Email with the required attachments in different formats.
6. CONTROL_FORM:

 This function module is used to control the form by creating the pages or
windows dynamically.
 Note: An icon Transport (Lorry icon) or in the menu path, Graphic -> Transport is used to
generate transport request to release Logo's form one system to another system.

6) What are the different ways to debug the Script?

Ans: - There are two ways to debug the Script Form.

 The path SE71 --->Utilities --->Activate debugger.
 By executing Standard Program/ Report 'RSTXDBUG'.
7) Differentiate between Page1 & Page2 format in sap script?
Ans: Page1 format: In this all pages have the same format.
Page2 format: In this there is variation in page format i.e. first page has different format than
second page.
8) Some of the useful Control commands/Statements in SAP scripts?
Ans:
1. /: Address…End address: It is used to display the address details of the given address
number in the standard format.
Syntax: /: ADDRESS
/: ADDRESS number &GS_KNA1-ADRNR&.
/: ENDADDRESS
2. /: Set Date mask: This command is used to print/format the system Date in the required format.
Syntax: SET DATE MASK = ‘<DD.MMMM.YYYY>’.
* Date: &DATE&
3. /: Set Time Mask: This command is used to print/format the system Time in the required format.
Syntax: /: SET TIME MASK = ‘ SS:MM:HH ’.
Note: Pass blank spaces to the formatted date & time to format them into default format.
 There is no loop statements in SAP Script forms but the text elements can be used to
communication with the function module WRITE_FORM used within the loop of the print
program to display the multiple entries.
Text Element:
 Text Element is the name give to the block of statements in the page window. If we pass the
text element name to the WRITE_FORM function module then the WRITE_FORM function
module transfers the data form driver program to all the statements which are available
under Text Element.
 Whenever we are working with main window, then we must provide Text Element name,
otherwise the 1st information printed twice.
4. Protect…End protect: It is used to print the continuous text without any page breaks in SAP
Script forms.1st the system checks each & every page which page is having the enough place
to print the continuous text. If no page is having enough space it simply break the text &
printing in different pages.
Syntax: /: PROTECT
/E ELE
/: ENDPROTECT
 5. Define: This command is used to define/declare the symbols in SAP Script.
Syntax: /: Define &GV_SYMBOL&
6. Box: This command is used to draw the Boxes/Frames on the page windows.
Syntax: /: BOX XPOS <**> cm/mm YPOS <yy> cm/mm
/: WIDTH <ww> cm/mm HEIGHT <yy> cm/mm
/: FRAME <FF> TW INTENSITY <yy> TW
Note: An addition INTENSITY is used to gray out the boxes.
 The command position & size can also be used to define the box position & sizes.
8. Top…End Top: This command is used to display/print the contents at the Top portion/Header
of the specified window.
Syntax: /: TOP
/* Display/Print at Top of page window.
/: ENDTOP
9. Bottom…End bottom: This command is used to display/print the contents at the
Bottom/Footer portion of specified window.
Syntax: /: BOTTOM
/* Display/Print at Bottom of page window.
/: ENDBOTTOM

boxes.
9. By using RSTXDBUG standard program we 9. By using BREAK-POINT keyword we can debug
can debug the SAP script. the smart form.

2) Why the Scripts are Client dependent and Smart Forms are Client independent?
Ans :-
 SAP scripts are client dependent that means, if we design the SAP script in one client
that is not reflected to other clients in the same server.
The Scripts are client dependent because the contents or data displayed using
the text elements. The text elements are client dependent hence the scripts are Client
dependent.
 SMART FORMS are client dependent that means if we design the SAP script in one client
that is automatically reflected to all other clients in the same server.
The Smart forms are client independent because one UNIQUE FUNCTION MODULE is
generated by the system while activating the smart forms. The generated function
module is client independent hence the smart forms are client independent.

3) What are the Transaction Codes associated with Smart Forms?

Ans :- 1. SMARTFORMS - To maintain SMARTFORMS.
2. SMARTSTYLES - To maintain the styles for smart forms.
3. SMARTFORM_TRACE - To debug the SMARTFORMS and activate the database tracer.

6) what are the components of Smart Form ?
Ans: 1. Smart Form Layout
2. Function Module
3. Print Program
7) What are the main components in Smart Form?

Ans: The main components are, 1. Global Settings 2. Pages & Windows
1. Global Settings: It is used to maintain the global settings, definitions which can be applied
across the mart forms. It is collection of Form Attributes, Form Interface & Global Definition
I. Form Attributes: These are used to maintain the smart form attributes & output such
are page format, style name etc. The default style for smart form is ‘SYSTEM’.
II. Form Interface: These are used to declare the variables, work areas & internal tables
which are needed to transfer the data from print program to layout. It is the system
generated function module with all the parameters except changing parameters.
III. Global Definitions: It is used to maintain the global definitions which can be used across
the different Global definitions.
a) Global Data: It is used to maintain the global data definitions such are variables, work
areas, Internal Tables etc.
b) Types: It is used to define the types which can be referred to declare internal tables &
work areas.
c) Field Symbols: It is used to define the field symbols.
d) Initialization: It is processed before the smart form pages & windows are processed. It
is used to extract all the required data from the database table &
process the extracted data. Import & Export parameters must be
specified before they are used.
e) Form routines: It is used to define the subroutines which can be called across the
smart form. It is used to define the currency/quantity fields as like the
DDIC tables/structures.
f) Currency/Quantity Field: It is used to define the Currency/Quantity Fields as like the
DDIC tables/structures.
2. Pages & Windows: It is used to design the different page formats & windows. Following
are the different nodes in smart forms.
a) Windows: They are positioned on the pages. Following are different type of windows.
 Main Window: It is used to display the continuous text on the pages. This window is
the default widow. Without main window also we can design Smart forms.
 Secondary window: It is used to print the different contents on each page (similar to
variable window in SAP Scripts).
 Copies window: It is used to the print the same document with multiple
copies with different headings.
 Final window: This is used to print the total amount after all the lines or line items
are printed.
b) Graphics: It is used to create a graphic node (window) to display the graphics/logos.
 c) Address: It is used to define the address node/window to display/print the
organization address/personal address/work place add/ress.
 The address can be determined dynamically also using an option Determine
Dynamically.
d) Text: It is used to display/print the contents of the different symbols/fields.
e) Table: A table is used to print the multiple entries/dynamic data of an internal table.
The Table node can be used as template to display static record by un-checking the
checkbox internal table. Line types can be created under Table node.
f) Template: A Template is used to display the static data (single record). This node
does not have the separate header, main area & footer whereas, the table node
contains the different sessions such are header, main area & footer. The template
node can be used as table by defining it under loop node to display the dynamic data
as like the table node.
g) Flow logic: The flow logic nodes are used to control the nodes & define the program
lines in smart forms. Following are the different flow logic nodes.
I. Loop: It is used to process the corresponding nodes based on the number of
entries of an internal table.
II. Program lines: It is used to write ABAP source code. Input & Output
parameters must be filled with the data variables before they are used.
III. Alternative: It is used to control the corresponding nodes based on the
specified condition. It is used to process the alternative either True/False
process blocks based on the SET conditions.
IV. Command: This node is used to go to a new page based on the specified
conditions. This is used to break the page based on the condition.

custom table including the record details. So that we can know the custom table for the latest
details.

20) After running a BDC program in background, next day morning when you see the results, few
records are not updated(error records). What will you do then?
Ans: We will look into incorrect session, analyze the error screen, and reprocess the session after
correcting the data.
21) You are given functional specs for a BDC program and you need to decide whether to write a
method call transaction or a session. How u will decide?

Ans: Based on the amount of data (number of records to update), I will decide what method to use.

Ex: If data is less the 5000, I will use call transaction.

If data is more than 5000 records I prefer session method.

22). How to handle screen Resolution?

Ans:

 Declare a structure data variable of the type ‘CTU_PARAMS’.

 Pass the required data such as default size, display mode, update mode etc to the
defined ctu_params structure variable.
 Use the populated structure variable of type ‘ctu_params’ with CALL TRANSACTION
using an addition ‘OPTIONS’.

23) How to handle Table Control in BDC?

Ans :- Table control is used to migrate/update the multiple records(line items) in BDC.
Note:
 Press Page Down in the table control to record the function code for page down.
 The next item no is the 1st item no when the Page Down is pressed.
 Record the Screen flow with line items using the T-Code “SHDB”.
 Convert the recording into a program using the button program.
 Make the changes in the original main program like,
 Upload the flat file data which contains both Header & Item data.
 Split the uploaded Flat file data into the Header and Item tables, using
the Control Break Statements.
 Set a loop to Header internal table then process the Header related data by copy & paste
the system generated header related sub-routines from the temporary recording program
 Set a loop to Item table data to process the multiple line items.
 Make the Item number as dynamic by concatenating the screen field name with the
screen number.'
 Use the function code “p+” to handle page down in table control.
 Use any one of methods with BDC_INSERT(Session) or CALL TRANSACTION to migrate
the data from internal table GT_BDCDATA.
Note: The Header & Item data can be processed separately using the control break statements
without splitting the flat file data.

The control break statements can also be used to process Header & Item data separately by
avoiding nested loops.

24) What are the problems in processing batch input sessions? How is batch input process different
from processing on line?

Ans: 1) If the user forgets to opt for keep session then the session will be automatically removed
from the session queue (log remains). However, if session is processed we may delete it
manually.

2) If session processing fails, data will not be transferred to SAP database table.
ENHANCEMENTS
 Enhancements
1) What is Enhancements and what are the different techniques and explain them?
Ans :- Enhancements are used to add some additional customer specific functionality to the
standard applications/programs.
1. Customer Exits: These are the Function Modules available in most of the functional
areas such as SD, MM, FICO etc. They are used to add the additional functionalities in
the standard applications/programs without using access key to break them. The
access key is the unique key provided by the BASIS consultant to break the standard
applications. The application will become custom development once they are broken.
 Field Exits: These are used to change the field labels of the standard data
elements.
 Function Exits: These are used to add the additional functionality to the
standard programs without breaking them. Each Function Exit contain a
custom include program which starts with Z* to implement the customer
specific additional business logic. The Function Exit is the 3 digit no which is
called using the ABAP statement CALL CUSTOMER_FUNCTION.
 Menu Exits: These are used to add the custom specific menu items &
corresponding additional functionality based on the selected menu item.
 Screen Exits: These are used to add the additional screen elements & the
corresponding additional functionality to the standard screens/transaction.
 T-Code SMOD: It is used to find the customer exits of the standard package.
 T-code CMOD: It is used to assign an enhancement/exit to project.

2. User Exits: These are the Sub-routines which start with USEREXIT_* & these are
defined in the standard Include programs. They are mostly used in SD functional area.
The Access key is required to break the standard Include programs of the User Exits
for the first time. The T-code SPRO is used to find the User Exits.
3. BTE (Business Transaction Events): These are the Source code plug-ins to add an
additional functionality in the standard program.
 T-code BERE: It is used to find the BTE’s.
 T-code FIBF: It is used to work with BTE’s.
4. Enhancement Framework: The enhancement frame work is advanced to user exits for
adding an additional functionality without breaking the standard programs. It is used
to attach/hook the source code plug-ins such as enhancement section or
enhancement points in the standard programs.
 In User-exits we write code only in the form routines (ie., in Form...End Form). and
When we go for upgrade the versions, we again need to change the code in the user-exit
which we written in previous versions but with Enhancement Frame work there is not much
code change is required when we go for upgrades.
o BADI: These are new enhancement technique to add the additional customer specific
business logic to the standard programs.
2). what are the ways to find the Exits?

I. Using the T-code Package name of the applications

II. Using the T-code SE84
 Find the package name of the required T-code.
 Execute the T-code SE84.
 Expand Enhancement folder
 Double click on enhancements
 Enter the required package name/Exit name
 Click on execute icon
III. Using the Find function in standard programs.
IV. Using the standard Tables MODSAP & MODACT
3) What are the types of Enhancement Frame work?
Ans:
 It is an advanced enhancements concept introduced from the version ECC6.
 It is used to attach/hook the source code plug-ins such as enhancements section or
enhancement points in the standard programs.
 There are 2 types of enhancement frame works.
1. Implicit Enhancement Section/Point: They are provided implicitly at the particular locations
by SAP. They are mostly presented at the beginning & end of the sub routines
(FORM-ENDFORM), beginning & end of the function modules, beginning & end of the
programs.
2. Explicit Enhancement Section/Point: They are pre coded by SAP & provided at the specific
location in the standard programs. There are 2 types of Explicit Enhancement.
 Enhancement-Section: It is used to copy, change the existing standard source
code & add additional business logic to the standard program. The ABAP
statement ENHANCEMENT-SECTION is used to specify the Enhancement
Sections.
 Enhancement-Point: It is used to add the additional customer specific business
logic to the standard program.
4) What are the differences between Customer Exits and User Exits?

Customer Exits User Exit

1. These are the Function modules 1.These are the subroutines
2. The Customer Exit have different type such as 2.User Exit do not have different types
function exit, menu exit, screen exit & field exit
3. These are available under most of the 3.These are mostly available in SD functional
functional areas such as SD,MM,FI etc area
4.Access key is not required to add the 4.Access key is required to break the standard
additional functionality program
5.The Customer Exits are called using 5. The User Exit starts with
CALLCUSTOMER_Function USEREXITS(subroutines in standard include)
5) What are the Transaction Codes associated with BADIs?

Ans :-
T-code SE18 & SE19: are used to work with the BADI’s
T-code SE18: used to define the BADI’s
T-code SE19: used to implement the BADI’
6) What are the types & sub types of BADIs and explain about them?

Ans :- It is used to add the additional customer specific business logic to the standard programs.
1. Classic/Old BADI: These are mostly used in the functional areas like SD, MM, FI/CO. The
standard method “GET_INSTANCE” of the standard class “CL_EXIT_HANDLER” is used to
work with the classic BADI’s.
2. Kernel/New BADI: The ABAP statements “GET BADI & CALL BADI” are used to work with
New BADI’s. It is faster than Classical BADI’s.
GET BADI: This statement is used to generate a New BADI object & sets the BADI
reference to the objects in the BADI reference variables.
CALL BADI: This statement is used to call the Methods of the New BADI’s.
Subtypes:

a. Single use BADI: The single use BADI can’t be implemented for multiple times. This BADI
can have only one implementation.
b. Multiple use BADI: The multiple use BADI’s can’t be implemented for the multiple times.
c. Filter Dependent BADI: It is used to control the BADI implementation based on the
specified filter value. The system generates an Import parameter ‘FLT_VAL’ to pass the
filter values for controlling the business logic of the BADI implementation.
 Interface: It is a separate structure which can be used to extend the scope of a class.

7) What is FALL BACK class in BADI?

Ans :- If a BADI doesn’t have any active implementations, the program goes to run time error.
The Fall back classes are used to call the default methods in case of a BADI doesn’t have
any active Implementations.
 The exceptions can also be raised to avoid such kind of errors.

8) What are the differences between Exits and BADIs?

Ans :-
Exits BADIs
1. They are procedural ABAP based 1. They are Object Oriented ABAP based
2. It is not possible to assign an Exit to more 2. The multiple use BADI can be implemented
than one project For multiple times
3. The Filter values can’t be set to the Exits 3. The Filter values can be set for Filter
Dependent BADI’s
4. The T-codes SMOD & CMOD are used 4. The T-codes SE18 & SE19 are used
9) What are the ways to find BADIs?

Ans :-
 Most of the Standard BADI’s are classic BADI’s.
 They are used to add the additional customer specific functionality/business logic to the
standard programs/T-codes.
 There are 4 ways to find the BADI’s
I. Using the standard class CL_EXITHANDLER
 Execute the T-code: SE24 to maintain the global class.

BADI. Ex: BADI_MATERAIL_CHECK
II. Using the T-code SE84
III. Using the T-code ST05 (SQL Tracer)
IV. Using the T-code SPRO

10) What are the differences between Classic (Old) BADI and New (Kernel) BADI?

Ans :-
Classic or Old BADI New or Kernel BADI
1. The standard method GET_INSTANCE of the 1. The ABAP statements GET BADI & CALL
standard class CL_EXIT_HANDLER is used to call BADI are used to work with New BADI’s.
2. An interface of a BADI referred to create the 2. The definition of a BADI is referred to create
Reference object the Reference object
3. It is not faster as like the Kernel BADI 3. It is faster than the Classic BADI
4. It can be a multiple use BADI 4. It must be a single use BADI
5. The Fall back class can’t be defined 5. The Fall back class can be defined
6. It can be a Filter Dependent BADI 6. It is not possible to maintain the Filter values

11) What are the statements not be used in Exits and BADIs?

Ans :- The ABAP statements COMMIT work & ROLLBACK work should not be used in EXITS.
The ABAP statements STOP & EXIT are also not advisable.
12) What are the Enhancement Spots?

Ans :-
 The enhancement spots are used to manage explicit enhancement options that means you
can add your code in standard ABAP code without need of access key, which implies that
the standard code is not disturbed.
 Enhancement spots specify the places where we can add our code in standard SAP.
Each enhancement spot element definition must be assigned to at least one enhancement spot.

13) What are the steps to insert the Enhancement Spot and work?

Ans:
 Implicit enhancement Spots are available in every program on some predefined spots as a
begin of FM, end of FM, begin of some event and so on. It means that you can easily modify
any program, FM, subroutine with some limitations.

 If you want to see all implicit spots in program,

go to SE80 -> Edit -> Enhancement Operations -> Show Implicit Enhancement Options

14) How to control the multiple implementation of BADI ?

ANS:
The standard filter dependent BADI : BADI_LAYER can be Implemented to control
multiple implementation of BADI (OR) by using Filter dependent BADI (or ) Extracting all
BADI Implementations from V_EXT_IMP or V_EXT_ACT Data base Views.
Cross Applications/Interfaces
(RFC, BAPI, IDOC)
 Cross Applications (RFC, BAPI, IDOC)

1. What is the Cross Application/Interfaces concept?

Ans: - This concept is used to distribute the data between SAP to SAP systems
(SAP R/3 <-> SAP CRM) & SAP to Non SAP systems (SAP <-> .NET, JAVA)
2) What is Remote Function Call (RFC) & types of RFC’s?
Ans:
 It is a SAP specific protocol to provide communication between different systems.
 It is the process of calling Function modules from another system.
 SAP Uses CPIC (Common Programming Interface for Communication) Protocol to transfer
data between Systems.
Types:

1. Synchronous RFC: In case of this RFC both the Sender/Source and Receiver/Target
systems should be available while distributing the data. The next part of calling program
isn’t continued until call function is completed.

2. Asynchronous RFC: In case of this RFC both the Sender/Source and Receiver/Target
systems should not be available while distributing the data. The next part of calling
program is continued without completing call function.

3. Transactional RFC (TRFC): It is almost similar to Asynchronous RFC. The Transactional

RFC is executed only once in an RFC server & save the corresponding data under unique
transaction ID in the Database.

4. Queued RFC: In case of this RFC the multiple transactional RFC’s are serialized in the
sequence using the Function module ‘TRFC_SET_QUEUE_NAME’.

 An additional statement ‘Destination’ is used while calling Remote Enabled Functions.

3) How to Debug RFC Function module?

Ans:

 SE38 -> Utilities -> Settings -> ABAP Editor -> Debugging activate the external debugging
and choose the New Debugger option in ABAP debugger.
 Go to the particular place in the code and put break point, pop will appear then choose the
HTTP break point.
 If you are triggering the RFC from SAP portal make sure that both the user ID should be
same If the users are different then provide the XI/Portal User ID in the users field.

4) How do you connect to the remote server if you are working from the office for the client in
remote place?
Ans: WAS -> Web Application Server or ITS (Internet Transaction Server) are generally used for this
purpose. If you are sitting at your office with a server which is in the system and the other server is
at the clients place you can generate IDOC, Intermediate Documents which carry the data you want
to transfer or the documents you want to transfer, these IDOC are interpreted by the system at the
receiving end with the message class with which it is bound with. If you want to logon a system
which is very distant, then remote login can be used this depends on the internet speed.

5) What are the steps to work with Remote Enabled Function/maintain RFC connection?

Ans: An additional statement ‘Destination’ is used while calling remote enabled functions.

1. Define RFC Destination: 2. Creation of Remote Enabled Function: SE80

 Execute the T-Code : SM59

 Select the required RFC connection such as ABAP connections/Type 3 connections.
 Click on create icon
 Enter RFC destination name & Description : SAP R/3 to SAP CRM
 Enter the target application server name/address in the target host field : CRM system
 Enter the target system number Ex: 33
 Click on “Logon & Security” tab
 Enter the logon credentials of the Receiver/Target system

Note: The check box Current user can be checked to make use of the same User name & password
for the target system

 Click on save icon & click on yes button

 Click on ‘Connection Test’ button to test RFC destination
 Click on ‘Remote Logon’ button to test the remote connection

6) How to make Destination (system-id) as dynamic?

Ans: IF Sy-sysid EQ ‘CMD.

<gv_dest> = ‘R3D’.

ELSEIF Sy-sysid EQ ‘CMQ.

<gv_dest> = ‘R3Q’.

ELSE Sy-sysid EQ ‘CMP.

<gv_dest> = ‘R3P’.

*Call RFC

CALL FUNCTION ‘ZRFC/RFC’

DESTINATION <gv_dest> “R3D

7) What are the differences between RFC and BAPI?

RFC BAPI
1. RFC’s are used to connecting from SAP to 1. BAPI is used to connecting from SAP to SAP
SAP only as well as SAP to NON SAP
2. The T-code SE37 can be used to find RFC’s 2. The Tcode BAPI &SE37 can be used to find
the BAPI
3. RFC doesn’t generate any methods 3. BAPI generates the unique method in BOR to
 use in the external system directly
4. It doesn’t have standard RFC’s to migrate the 4. The standard BAPI which starts with BAPI can
data be used to migrate the data

8) What are the steps involved in creating Custom BAPI?

Ans :-
1. Create the BAPI structure (SE11) starts with ZBAPI*.
2. Create the BAPI function module (SE37) starts with ZBAPI* which is
a) Remote Enabled
b) All parameters are pass by value
c) Must contain Return parameter
3. Create method & object for the BAPI remote enabled function in BOR using the T-code
‘SW01’.
4. Generate, implement & release the created BAPI to the outside using the T-code - ‘SQO1’.

9) What are the ways to find Standard BAPIs?

4. Double click on the required BAPI
 Corresponding BAPI details such as method name, business object name, BAPI
function module & etc are displayed under details tab
 The tab Documentation is used to know more details about the BAPI’s (standard)
 The tab Alphabetic can also be used to find the BAPI’s in the alphabetical order
5. Click on back
11) What are the steps to work with standard BAPI?
Ans:
 Upload the flat file data into an internal table
 Convert the flat file data into BAPI compatible Work area’s/internal tables with in the loop of
the flat file internal table.
 Call the BAPI function module & pass the BAPI internal tables.

12) How to handle exceptions in RFCs and BAPIs?

 Ans :- You can handle the exceptions by using a structure BAPIE1RET2 which returns the
messages captured in BAPI. In Tables parameter of your BAPI, you can create a structure as of
type BAPIE1RET2 so that you can capture the ‘RETURN’ parameters from BAPI.

13) How to handle error messages in standard BAPI’s?

Ans:
1. Get all the message details into a written table of the type BAPIRET such as Message ID,
Message type, Message variable etc.
2. Use the standard function modules ,
 MESSAGE_INITIALIZE ( Initialize messages),
 MESSAGE_STORE (To store messages) &
 MESSAGES_SHOW (To display messages in the Dialog box/Model dialog)

14) What is Extended BAPI?

Ans:
 Standard BAPI’s can be extended to add the customer specific additional field.
 Standard BAPI contains table’s parameter EXTENSIONIN, EXTENSIONOUT in case they are
extended BAPI’s.
 BAPI extensionin is used to update custom fields of a table (ex: MARA).
 BAPI extensionout is used to retrieve custom fields of a table.
15) What are the differences between BAPI and normal BDC?

BAPI BDC
BAPI is faster than BDC. BDC is relatively slower than BAPI.

BAPI’s are used to upload the data from the flat file to BDC’s are used to upload the data from
SAP system directly. file to SAP system via screens hence it is
slower.
No such processing options are available in BAPI. Background and Foreground processing
options are available for BDC.

BAPI would generally used for small data uploads. BDCs would be preferred for large
volumes of data upload since
background processing option is
available.
BAPI never cause to terminate the program. Whenever Errors can be processed in SM35 for
an error occurred in the BAPI, it returns those errors session method and in the batch input
through Return parameter. This parameter returns program for Call Transaction method.
exception messages or success messages to the
calling program.
In BAPI recording is not required In BDC, recording is required

not then we execute RBDMOIND standard program.
4. The status of an IDOC (3) use in Green color (turn 10 to12) means it is delivered
Successfully. Yellow traffic light indicates/the status code remains same, IDOC is in
Progress or in the Transaction RFC & Red traffic light/the status code turns 10 to 11
indicates the Error/the IDOC is damaged.

27) How to add Segments to an Existing IDOC?
Ans :-
 You can do that using WE30 and WE31.WE30 you can create extension to the existing Idoc
type and WE31 you can add the fields to the sub segment. So first develop the segment
using WE31.you need to create the extension first & then add it to the segment which ever
you want using WE30 with extension option.
 Here you have to create enhanced idoc type. In we31 create the segment type as per your
requirement and go to we30 and create enhanced Idoc type by coping the standard Idoc.
After that you will select the segment under which you want to add the new segmnt and
press create button on the application tool bar and give the details of your new segment and
save it.

 Just click enter if you find any information message and add fields as below.

Save it in a local object.

3. Create IDOC type. Go to WE30, provide name as ZSTUDENT and click on create

Provide description and press enter.

 Select ZSTUDENT and click on create.

Provide a segment name (which we have created in step2), maximum and minimum numbers and
enter.

Save it in a local object.

 4. Create message type. Go to t-code WE81 and click on change icon.

Provide message type as ZSTUDENT and description.

5. Assign message type to IDOC type. Go to t-code WE82, click on change and click on new
entries.

Provide message type, IDOC type and release as below.

Save it in a transport request.

6. Define logical system.

This is the most confusing step in ALE configurations, try to understand carefully.

What is logical system?

'Logical system' is used to identify an individual client in a system, for ALE communication
between SAP systems. That's why you see a field for ‘logical system’ in the client master
data in SCC4 (table T000). You use logical systems in ALE configuration - this should be
documented further in the IMG guide, or SALE transaction.

Before creating a logical system please follows below steps.

 In a blind way logical system assigned in target system client (in our example 810 client)

Should be in logical system definition in source client.

Step1: Go to target system( In our example 810 client).

(Get logical system from t-code SALE ->Basic Settings ->Logical Systems -> assign logical system
to client -> 810 (double click and copy logical system)).

Step2: Go to SALE.
Expand basic settings -> define logical system.

Check for logical system existence (which we get from 810 client) if it is there, no need to add, if it is
not there add it.
7. Assign logical system to client. For now skip this.

8. Create RFC destination.

Go to T-code SM59, select ABAP connections and click on create.

Provide RFC destination, description, hostname and system number.

 Click on logon and security tab, provide client, user name, password and save.

Click on connection test to test connection.

 Click on remote logon to logon to remote client (you will go to 810
client).

Step9: Create PORT in WE21.

Go to t-code WE21, select transactional RFC and click on create.

Select generate port name and enter.

Provide RFC destination, which we created in step8.

Save.
10. Check partner profiles in WE20.

Go to WE20, expand partner type logical system and search for logical system (Get logical
system from t-code SALE ->Basic Settings ->Logical Systems -> assign logical system to client ->
810 (double click and copy logical system)).

If logical system is already available in partner profiles in WE20, we don`t need to create partner
profile again instead we will add message type at out bound parameters level. In my case, logical
system is already available in partner profiles so I will add ZSTUDENT message type to it. To add
message type, select logical system, click on add icon (see below image).
Provide message type, receiver port (which we have created in step9), select transfer IDOC
immediately, basic type and save.

If logical system is not available in partner profile in WE20, select partner type logical system and
click on create.
 Provide partner no as T90CLNT810 (Get logical system from t-code SALE ->Basic Settings
-> Logical Systems -> assign logical system to client -> 810 (double click and copy logical
system). Save and add message type at out bound partner level.
Steps to be done in 810 (Target System) clients.
Continue 1 to 7 steps as same as 800 client.

1. Create a table (client dependent).

2. Create segments.
3. Create IDOC type.
4. Create message type.
5. Assign message type to IDOC type.
6. Define logical system.
7. Assign logical system to client.
8. Create inbound function module SE37.

Every inbound IDOC will have process code, every process code is associated with a inbound process
ex: Function Module or Work Flow Task.

Follow below steps to create inbound function module.

1. Create a function group in SE80.

2. Copy Function module IDOC_INPUT_MATMAS01.
3. Add your own code.

Step1: Go to SE80, select function group, provide a name ZSTUDENT_IDOC, enter.

Save and activate function group.

Step2: Go to SE37, provide function module name as IDOC_INPUT_MATMAS01, click on copy, provide
function module name as function group and enter.
Step3:Add your own code in function module. Go to Se37, provide name as
ZSAPN_IDOC_INPUT_STUDENT, and click on change. Remove all code and add below code.

PROJECT
 PROJECT

1) What is System Landscape?

Ans: Landscape is an arrangement of servers.

a) Development system: It is an environment where all the developments, configurations &

Changes are done. This system contains at least 2 clients & an optional sand box client.
 Development client: It is used to develop the objects, change the existing objects &
maintain configuration changes.
 Unit test client: It is used to perform unit test for preparing Unit Test Document.

Sandbox system: It is an environment to develop the objects, make the changes & maintain
configurations at initial stages of the projects. All the consultants are authorized for any
transaction code in this system. This system is an optional system.

b) Quality system: It is an environment where all the developments, configurations & changes
are tested without any errors by the functional, technical consultants & end users.

c) Production system: It is an environment where all the end uses work. It is the live system
Where all the original data is maintained. This system contains a single client.

2) What is Package & Transportable Objects?

 Package: It is a collection of transportable objects. The package is used to save all

the transportable objects.
 Transportable Objects: They must be saved under the required package. The system
generates the unique Transport Request number while saving the objects under the
package. The transportable objects can be released from one system to another system.

3) Explain about Correction and Transportation System (CTS) or Transport Organizer?

Ans :- This tool is used to record the changes made in the system.
 It is also used to release the Transport Request (TR) from one system to another
system (Dev --->Quality ---->Production).
 When the change request is created either manually or automatically, the system
assigns a number to it automatically and this number is known as change request
number. The change request records all modifications made to development
object. When the changes have been made and the change tasks have been
released, the change request can be released.
 The T-Codes SE01/SE09/SE10 is used to work with this tool (CTS).
Note: The T-code SE03 is used to find TR of objects

The T-code STMS is used to Import TR’s

 This documentation provides you with an overview of how to manage changes with the CTS
and essential information on setting up your system and client landscape and deciding on a
transport strategy. Read and follow this documentation when planning your development
project
4) What are the differences between SE01, SE09 and SE10?

Ans : SE01 - Correction & Transport Organizer

SE09 - Workbench Organizer

SE10 - Customizing Organizer

5) How to import the Client dependent/Script changes/Table entries into the Unit Test system?
Ans :- Using the SCC1 in the test client (220)
 Enter the TR no
 The source client no (200) is appeared by default
 Check the check box Including Request Sub Tasks
 Click on Start Immediately button & press Enter button.
6) What are types of Transport Requests (TR) and Explain about them?

Ans: Transport request: - It is a unique request number generated by the system while saving the
object under the package name. The TR’s are generated in development client only & release
them from development client. The TR no is starts with development system id followed by
K-series. Ex: <R3D>k9<****>
The Transport requests of 4 types.
 Customizing Requests: These are used to record & release the configuration changes in
the system.
 Work bench requests: They are used to record the changes/workbench objects such as
DDIC objects (Tables, Structures, Transaction codes), Programs, Function modules etc &
release them from one system to other.
 Transport of Copies: They are created to transport the configurations, developments &
changes from one system into another system.
 Relocations: They are used to change the objects from one package to another package.
7) How to generate Transport Request (TR)?

Ans:

 Enter the package name at the time of saving with objects Ex: ZDEV/ZSD/ZMM…
 Click on save icon
 Click on create request icon
 Enter short description as per the project standards Ex: <CR547895 – Sales Report>
 Click on save icon & click on yes button

8) How to change short description of TR?

Ans: Once the transport requests are displayed in transport organizer,

 Double click on the required TR -> click on properties tab

 Click on display/change
 Change short description as per the project standards -> click on save & back
9) How to release Transport Request?

Ans:

 Execute the T-code: SE09/SE10/SE01.

 Check all the check boxes
o Customizing requests
o Workbench requests
o Modifiable
o Released
 Click on display button.
 Expand the required TR no under modifiable status.
 Place your cursor on the task number.
 Click on release directly or F9.

Note:

 The objects under the TR must be activated before the transport requests are released.
 The tick marks are appeared beside the task numbers once they are released.
 Place a cursor on the TR number after all the corresponding tasks are releases.

10) How to delete Transport Request/Object from TR?

Ans:

 Execute the T-code SE09/SE10/SE01

 Click on display button.
 Expand the required TR under modifiable status
 Expand the corresponding task number -> right click on object name -> click on delete ->
click on yes button -> click on yes button.

Note: Follow the similar steps to remove any number of objects from the task/TR.

 Place the cursor on the task number after all the corresponding objects are deleted.
 Click on delete & click on yes button
 Place the cursor on TR after all the corresponding tasks are deleted
 Click on delete icon -> click on yes button.

11) How to change package name of an object?

 Execute the required T-code : SE38, SE11 Etc

 Click on ‘Go to’ from menu
 Click on ‘object directory entry’
 Click on display/change icon
 Change the package number Ex: $TMP -> ZPACK
 Create the TR by pressing create request
 Click on tick (yes)

12) What is Technical Specification (TS)?

Ans: It is a document prepared by technical consultant (ABAPer).This contains all the technical
details such as the Technical solution for the requirement. The detailed TS contains all the details
such as starting from designing the Selection screen, Declarations, all the Function Modules used &
the processing logic to meet the customer requirements, unit test cases etc.
13) Roles & responsibilities for support project?

Ans: Implementation Process

• Getting the business Requirement document from functional consultant / functional analyst.

• Analyze the business Requirement.

• Analyze the estimated time for development.

• Development of Object (ABAP application).

• Unit Testing by Developer.

• Releasing the object to testing environment.

• Prepare technical document of the development.

Support Process
• Receiving tickets/issues from business.
• Analyzing the ticket.
• Resolving the issue in time.
• Developer testing and transporting.

14) What are the performance tips do you follow while developing an object? (Or)

What are the performance tips do you follow to improve the performance in the given program?
Ans: 1) Don't use Select - End select loop (Normal search) since it hits the database for each record
& Use INTO table statement (Pointer search) to extract all the required data into an
internal tab in single step.
2) Don’t use select * while extracting data since it extracts all fields & Use select followed by
the required fields in the similar order of the database tables.
3) The internal Table must be must sort internal tables before using control break statements.
4) The internal Table must be sorted internal tables before using binary search addition with
READ table statement for faster access.
5) Copy and delete internal tables/ db tables outside of the loop.
6) The Base internal table must be checked whether it has data or not before using the
FOR ALL ENTRIES Statement otherwise Select statement extracts all the records form the
database without considering FOR ALL ENTRIES.
7) The internal Table must be SORTED before DELETE ADJUSCENT DUPLICATES statement.
8) The TABLES statement is not advisable since it creates lot of implicit Work Areas.
9) Prefer Parallel Cursor method in case of Nested Loops.
10) Secondary Indexes are not advisable since the data is filtered at data base level for all the
users.
11) Up to 2 tables can be joined then use For All Entries while extracting the data from the next
required tables.
12) For All Entries with Inner Joins are advisable since For All Entries are another extra filter
criteria as like Select-Options.
13) Don’t use Select statements within the Loops. Use For All Entries outside of the loop
statements then use Read Table statement with Loop statements.
15) What is a Functional Specification?

Ans: Functional Specification is the official document for a developer which describes the features
and design of expected functionality. It contains the technical expectations and required data for
the design and development. The FS is also called as GAP. This can be prepared only after
discussing with the end users & understand their requirements & document the End users/ clients
requirement.

16) How do you get functional specs when you are assigned some object?

Ans: Generally Functional Specifications will be sending through emails (In support process, they
may come in a specific tool like: Remedy, Radix).

17) How do you receive Functional Specifications?

Ans: In general a functional specification will be sent to a consultant through organizational Email like :
Outlook, IBM Lotus etc.

Functions of Functional Specifications:

 Requirement.
 Design Summary.
 Desired Functionality.
 Finished product.
 Test Cases.

Functional Specification format/contents may differ from company to company, every company
follow their own formatting style.

18) Who prepares Functional Specifications?

Ans: As per standard Organizational structure, functional consultants will prepare functional
specifications, in some cases Techno-Functional consultants will prepare them. (In some
companies Senior-Technical Consultants may prepare).

19) What is the next step after Functional Specifications?

Ans: Once Functional Specification is prepared, the document will be sent for approval to functional
head or project manager, once approved, it will send to technical lead. The technical lead will
distribute the Functional Specification to any developer.

20) Client concept: If there are two clients in development server, Ex: client 200 for development and
client 300 for configurations, what does it actually mean?

Ans: Even if there are two clients 200 and 300, 200 for development and 300 is for configuration, you
cannot access 200 client data in 300 client.

In real-time, functional people need accurate data to test business configuration(SD/MM/FI etc),
when it comes to technical people, they may create junk data to test their application(Creating
material, junk master data, junk transaction data etc), so they maintain one separate client(200) for
development activities and separate client for configurations.

Note: Transport path will be same for two clients (200 - QA) and (300 - QA) i.e.; same QA client.
