Understanding Demand Management in SAP PP

In production planning, anticipating customer needs is crucial. That’s where Demand Management in SAP PP comes in. It’s the process of forecasting and managing the requirements for finished products, ensuring you have the proper inventory at the right time.

The Key Player: Planned Independent Requirements (PIRs)

SAP PP uses Planned Independent Requirements (PIRs) as the cornerstone of Demand Management. A PIR tells the system: “We need X quantity of this product by Y date.” This information, independent of sales orders, feeds into Material Requirements Planning (MRP), which calculates the dependent requirements (raw materials) needed to fulfill the PIRs.

Two main planning strategies utilize PIRs:

• Make-to-Stock (MTS): Here, production happens based on forecast demand, not actual sales orders. PIRs become the sole source of demand for MRP.
• Mixed Planning: This strategy considers both PIRs and sales orders. It offers more flexibility but requires careful planning to avoid over or under-production.

Benefits of Demand Management in SAP PP

• Improved Production Planning: Accurate forecasts through PIRs lead to efficient production scheduling and resource allocation.
• Reduced Inventory Costs: By anticipating demand, you can avoid overstocking and the associated storage and carrying costs.
• Enhanced Customer Satisfaction: By having the right products in stock, you can fulfill customer orders promptly, leading to higher satisfaction.
