Material Requirements Planning in the Make-to-Order Scenario
Material requirements planning (MRP) is carried out for the configurable forklift's material number through the MRP run. The MRP run identifies the individual customer requirement from the customer order—in this example, customer order number 92. This identification is controlled by the requirement type "KEK" (German: Kundeneinzelkonfiguration, or customer individual configuration) in the customer order item.
The MRP run incorporates the variant configuration from the customer order item for the forklift truck into the generated planned order. In the configuration used here, all assemblies—including configured assemblies such as counterweight, motorization, etc.—have the collective requirement indicator set in their material master records.
Key Implications:
- There is no separate planning for configured variant assemblies in this MRP run
- Variant assemblies are planned differently, such as based on inventory development
- The company maintains inventories for all variants
If the variant assemblies were controlled based on individual requirements, the MRP run would have:
- Generated a separate planned order for each variant assembly controlled by individual requirements, or
- Created a purchase requisition for materials identified as external procurement items
This individual-requirement approach wasn't used in this scenario because it would have significantly increased complexity—especially in the subsequent exercise. Since the focus is on profitability accounting, we opted for collective requirement planning instead of individual requirement planning.
