• What is the cause and solution for SAP error message /SCMTMS/MSG253 - Document '&2 &1' is already locked by yourself in another session ?

  The SAP error message /SCMTMS/MSG253 Document '&2 &1' is already locked by yourself in another session typically occurs in the SAP Transportation Management System (TMS) when a user tries to access or modify a document that is already locked by the same user in a different session. This locking mechanism is in place to prevent data inconsistencies and ensure that only one session can modify a document at a time.
  Cause:
  
  Multiple Sessions: The user has opened multiple sessions in SAP and is trying to access the same document in more than one session.
  Unfinished Transactions: The user may have an unfinished transaction or process that is still holding a lock on the document.
  Session Timeout: Sometimes, if a session is left open for too long, it may still hold a lock even if the user is not actively working in that session.
  
  Solution:
  
  Close Other Sessions: Check if you have multiple SAP sessions open. If so, close the other sessions that are accessing the same document.
  Log Out and Log In: If you are unsure which session is holding the lock, log out of SAP completely and then log back in. This will release any locks held by your user.
  Use Transaction SM12: If you have the necessary authorizations, you can use transaction SM12 to view and delete locks. However, be cautious when doing this, as it may affect other users if they are legitimately using the document.
  Wait for Lock Release: If the document is locked by a process that is still running, you may need to wait until that process completes and the lock is released.
  Contact Support: If the issue persists and you cannot identify the cause, consider reaching out to your SAP support team for assistance.
