Summary :
This SAP Note addresses multiple issues and questions surrounding PP/DS planning runs in APO, particularly using the heuristic SAP_MRP_001. Key points include the configuration of parallel processing of MRP to avoid multiple planning instances of the same product, the implications of such multiple planning on system performance, and how to effectively handle these with segregation of planning runs. Guidance is provided on managing separate sub-selections in the planning process, setting up parallel execution correctly to prevent loss of performance, and using the customizing tools to ensure efficient planning practices that avoid repeated data processing and redundant receipt elements. Additionally, the terminology and prerequisites essential for understanding and implementing these changes in the system configuration are explained.
