This error typically occurs in the context of warehouse management processes in SAP Extended Warehouse Management (EWM).
  Cause:
  The error is usually caused by one of the following scenarios:
  
  Duplicate Work List Entry: An attempt is being made to create a new execution work list for a processor when one already exists for the same step and location.
  Concurrency Issues: Multiple processes or users may be trying to create or modify the same work list simultaneously, leading to conflicts.

  Check Existing Work Lists:

  Process or Delete Existing Work List:
  
  If the existing work list is valid, ensure that it is processed before attempting to create a new one.
  If it is no longer needed, you may delete it to allow the creation of a new work list.
  
  
  
  Review Configuration:
  
  Check the configuration settings related to work list processing in your SAP EWM system. Ensure that they are set up correctly to avoid conflicts.
