  Cause:
  
  Concurrent Access: Another user is currently editing or has locked the tax exemption record you are trying to access.
  Session Timeout: A previous session may not have released the lock due to a timeout or an unexpected termination.

  Solution:
  
  Wait and Retry: If the record is locked by another user, wait for them to finish their task and then try again.
  Identify the Locking User: You can use transaction codes like SM12 (to view and manage locks) to identify which user has locked the record. If necessary, you can contact that user to coordinate access.
  Release the Lock: If you have the necessary authorizations, you can manually release the lock using transaction SM12. However, be cautious with this approach, as it may disrupt the other user's work.
