Objectives
After completing this chapter, you will be able to: Describe the steps in the production planning process of a high-volume manufacturer such as Fitter Snacker Describe Fitter Snackers production and materials management problems Describe how a structured process for Supply Chain Management planning enhances efficiency and decision making Describe how production planning data in an ERP system can be shared with suppliers to increase supply chain efficiency

Introduction
Supply Chain Management (SCM) in an ERP system Fitter Snacker is part of a supply chain FSs SCM problems and how ERP can help fix them
Production Overview
To meet customer demand efficiently, Fitter Snacker must:
Develop a forecast of customer demand Develop a production schedule to meet the estimated demand
ERP system is a good tool for developing and executing production plans Goal of production planning is to schedule production economically
10
Sales Forecasting
SAPs ERP system takes an integrated approach
Whenever a sale is recorded in Sales and Distribution (SD) module, quantity sold is recorded as a consumption value for that material

CO module
Profit goals for company can be set Sales levels needed to meet the profit goals can be estimated
16
Once SAP ERP system generates a forecast, the planner can view the results graphically Rough-cut capacity planning applies simple capacityestimating techniques to the production plan to see if the techniques are feasible

Demand Management
Links the sales and operations planning process with detailed scheduling and materials requirements planning processes Output: master production schedule (MPS)
Production plan for all finished goods
For Fitter Snacker, MPS is an input to detailed scheduling, which determines what bars to make and when to make them

Planner can convert a planned order to a purchase order from Stock/Requirements List by double-clicking the planned order line

Detailed Scheduling
Detailed plan of what is to be produced, considering machine capacity and available labor One key decision in detailed production scheduling
How long to make the production runs for each product Production run length requires a balance between setup costs and holding costs to minimize total costs to the company

Receiving department must match goods receipt with purchase order that initiated it When receipt is successfully recorded, SAP ERP system immediately records the increase in inventory levels for the material

Advantages
Reductions in paperwork Savings in time Other efficiency improvements

Concepts in Enterprise Resource Planning, Third Edition 43
With ERP system, sharing production plans along the supply chain can occur in real time
44
SCM costs
Include cost of buying and handling inventory, processing orders, and information systems support
45
On-time performance
If supplier agreed to requested delivery dates, tracks how often supplier actually met those dates
46
Summary
ERP system can improve the efficiency of production and purchasing processes
Efficiency begins with Marketing sharing a sales forecast Production plan is created based on sales forecast and shared with Purchasing so raw materials can be ordered properly
47
Summary (contd.)
Companies can do production planning without an ERP system, but an ERP system increases companys efficiency
ERP system that contains materials requirements planning allows Production to be linked to Purchasing and Accounting This data sharing increases a companys overall efficiency
48
Summary (contd.)
Companies are building on their ERP systems and integrated systems philosophy to practice supply chain management (SCM)
SCM: company looks at itself as part of a larger process that includes customers and suppliers Using information more efficiently along the entire chain can result in significant cost savings Complexity of the global supply chain
Developing a planning system that effectively coordinates information technology and people is a considerable challenge
