  Reassign Elements: If you find that the reference elements are incorrect, you may need to reassign them to the correct WBS elements.
  Consistency Check: Use the transaction CJ_CHECK to perform a consistency check on the project structure. This can help identify any inconsistencies that need to be resolved.
  Review Change Logs: If recent changes were made to the project structure, review the change logs to identify what modifications were made and whether they could have caused the inconsistency.
  Consult Documentation: Refer to SAP documentation or help resources for specific guidance on handling WBS element hierarchies.
