This typically occurs in the context of SAP Master Data Governance (MDG) when there is an attempt to modify or lock a change request that is already being processed or locked by another user or session.
  Causes:
  
  Concurrent Access: Another user or process is currently accessing or modifying the same change request, leading to a lock conflict.

  Authorization Issues: The user may not have the necessary authorizations to lock the change request.
  
  Solutions:
  
  Check for Concurrent Users: Verify if another user is currently working on the same change request. If so, coordinate with them to avoid conflicts.
  Wait and Retry: If the lock is temporary, waiting for a few moments and then retrying the operation may resolve the issue.

  Authorization Check: Ensure that you have the necessary authorizations to perform the action on the change request. Consult with your SAP security team if needed.
