• What is the cause and solution for SAP error message WSTRN103 - Some prepacks are already used in logistics processes; check logs ?

  SAP Error Message:
  
  WSTRN103 Some prepacks are already used in logistics processes; check logs
  
  Cause
  This error occurs when you attempt to delete or modify prepack configurations (such as prepack materials or prepack assignments) that are already involved in ongoing or completed logistics processes. For example, the prepack might have been used in:
  
  Goods receipt or goods issue postings
  Production orders
  Stock transfers
  Sales orders or deliveries
  Warehouse movements
  
  Because these prepacks are referenced in transactional data, SAP prevents changes or deletions to maintain data consistency and integrity.
  
  Solution
  
  
  Check the Logs:
  
  The message suggests checking the logs to identify exactly which prepacks are involved and in which logistics processes they have been used. These logs can be found in the application or transaction where you tried to perform the change.
  
  
  Identify Usage:
  
  Use standard SAP reports or tables to find where the prepack is used. For example:
  
  Check material documents (table MSEG) for movements involving the prepack material.
  Check production orders (AUFK, AFKO, AFPO) if prepacks are used in production.
  Check sales documents (VBAK, VBAP) or delivery documents (LIKP, LIPS).
  
  
  
  Avoid Deletion or Modification:
  
  If the prepack is already used in logistics processes, you cannot delete or modify it directly. Instead:
  
  If you want to stop using the prepack, consider marking it as inactive or blocking it for future use.
  If you need to change the prepack configuration, create a new prepack material or assignment and phase out the old one.
  
  
  
  Data Cleanup (if applicable):
  
  If the usage is due to test or erroneous data, and you have authorization, you may consider reversing or deleting the related logistics documents (only if business processes allow and after proper authorization).
  
  
  Consult SAP Notes:
  
  Sometimes SAP releases notes or patches related to prepack handling. Check the SAP Support Portal for any relevant notes.
