  The SAP error message CJ454 indicates that a specific key (in this case, a WBS element) has been assigned multiple times in a way that is not allowed. This typically occurs in the context of project management within SAP, particularly when dealing with Work Breakdown Structures (WBS) and their assignments.

  Solution:
  To resolve the CJ454 error, you can take the following steps:
  
  
  Check Assignments: Review the assignments of the WBS elements in question. Ensure that each WBS element is assigned uniquely and not duplicated across different projects or cost objects.

  Deleting the duplicate assignment.
  Reassigning the WBS element to the correct project or cost object.
