  The SAP error message PMMO_DISTRIBUTION033 indicates that a specific Work Breakdown Structure (WBS) element is currently locked by another user. This typically occurs when multiple users are trying to access or modify the same WBS element simultaneously, leading to a conflict.
  Cause:
  
  Concurrent Access: Another user is currently editing or processing the WBS element, which locks it for other users.

  Identify the Lock: Use transaction code SM12 to check for locks on the WBS element. You can search for the specific WBS element and see which user has it locked.
  Contact the User: If you identify the user who has the lock, you can reach out to them to see if they can release the lock or if they are done with their work.
  Release the Lock: If necessary and if you have the appropriate permissions, you can manually delete the lock from SM12. However, this should be done with caution, as it may disrupt the other user's work.
  Check for Long Transactions: If the lock persists, check if there are any long-running transactions that need to be addressed. You may need to consult with your SAP Basis team to investigate further.
