  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

  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:
