This error typically arises in the context of Advanced Planning and Optimization (APO) within SAP, particularly when dealing with transportation planning and logistics.
  Cause:
  The error occurs when you attempt to delete or modify a transportation zone that still has customers assigned to it. This can happen if:

  Solution:
  To resolve this error, you can follow these steps:
