In materials requirements planning, the system determines production tasks as planned orders and procurement tasks as purchase requisitions. In this process, you execute multi-level requirements planning, starting with the finished product. This means that the system first determines the dependent requirements for the semi-finished products and raw materials defined in the BOM of material CH_5102. The system then explodes the semi-finished product requirements via the BOMs of these materials, which at the same time determines the dependent requirements of the respective materials. This applies to all components for which MRP type MRP has been defined in the material master. The BOM also contains a packing material with MRP type Reorder point planning (CH_3102)). As soon as the system detects a shortfall in the reorder point, the material is procured again. This procurement activity takes place independently of the BOM explosion for material CH_5102. The requirements planning run is also triggered independently.
