• What is the cause and solution for SAP error message PPH_MRP189 - Class item with cat.&1 for BOM comp.&2 not supported in MRP Live on HANA ?

  The SAP error message PPH_MRP189 indicates that a class item with a specific category is not supported in MRP Live when using HANA. This typically occurs during the Material Requirements Planning (MRP) process when the system encounters a Bill of Materials (BOM) component that is classified in a way that MRP Live cannot process.
  Cause:
  
  Class Item Type: The item in question is classified in a way that is not compatible with MRP Live. This could be due to the item being a class item (e.g., a configurable material) that is not supported in the MRP Live environment.
  BOM Configuration: The BOM may contain components that are not properly configured or are of a type that MRP Live does not recognize.
  MRP Live Limitations: MRP Live has certain limitations regarding the types of materials and BOMs it can process, particularly with respect to class items and their categories.
  
  Solution:
  
  Check Item Category: Review the item category of the BOM component. If it is a class item, consider whether it can be converted to a standard item type that is supported by MRP Live.
  Use Classic MRP: If the item must remain a class item, you may need to run the classic MRP (transaction MD01) instead of MRP Live (transaction MD02) for this particular material.
  BOM Review: Ensure that the BOM is correctly configured and that all components are compatible with MRP Live. You may need to adjust the BOM to remove or replace unsupported components.
  SAP Notes: Check for any relevant SAP Notes or updates that may address this issue. SAP frequently releases updates that may enhance compatibility or provide workarounds for known issues.

  By addressing the item category and ensuring compatibility with MRP Live, you should be able to resolve the error and proceed with your planning activities.
