In SAP S/4HANA, planning strategies (material master, MRP 3 view, Strategy Group) determine how production aligns with demand. The scenario describes a pure make-to-stock (MTS) environment where goods are produced based on forecasts (planned independent requirements, PIRs) and held in stock, with excess customer orders not affecting the production program:
* Make-to-stock production (10)(D): Strategy 10 uses PIRs (entered via MD61) to drive production, and finished goods are stocked (goods receipt via CO15). Sales orders (VA01) are fulfilled from stock, and excess demand beyond the forecast does not trigger additional production or consume PIRs-it's handled separately (e.g., via backorder or rejection). Thisensures the production program remains stable, based solely on the forecast.
Assembly processing with production orders (82)(A) is a make-to-order (MTO) strategy tied to sales orders, not forecasts.Planning with final assembly (40)(B) allows sales orders to consume PIRs, potentially impacting production if demand exceeds the forecast.Planning without final assembly (50)(C) plans subassemblies based on PIRs, with final assembly triggered by sales orders, also affecting production. Strategy 10 meets the requirement per SAP's MTS planning logic.

Collective orders are used to represent multilevel production structures for materials produced in-house, where the manufacturing order for the highest material in the structure automatically generates manufacturing orders for the semifinished products in the structure. This allows for an integrated view of the production process and avoids unnecessary placements in storage or removals from storage between production levels. Collective orders can consist of planned orders, production orders, or process orders, and each order has its own order number. Collective orders can be processed with or without automatic goods movements, depending on the business scenario.
