AO437 - Details

• The SAP error message AO437 indicates that you are trying to create a Work Breakdown Structure (WBS) element for a project definition that has been flagged for deletion. This means that the project is no longer active, and as a result, you cannot create new WBS elements under it.
  
  Cause:
  The primary cause of this error is that the project definition you are attempting to use has been marked with a deletion flag. This typically happens when a project is completed, canceled, or otherwise deemed inactive, and the deletion flag is set to prevent any further modifications or additions to the project structure.
  
  Solution:
  To resolve this error, you have a few options:
  
  
  Check Project Status: Verify the status of the project definition. If the project is indeed completed and should not be modified, you may need to create a new project definition instead of trying to add WBS elements to the existing one.
