• What is the cause and solution for SAP error message PU621 - Request &1 is already locked ?

  The SAP error message PU621 "Request &1 is already locked" typically occurs when there is an attempt to process a transport request that is already locked by another user or process. This can happen in various scenarios, such as when multiple users are trying to access or modify the same transport request simultaneously.
  Causes:
  
  Concurrent Access: Another user or process is currently working on the same transport request.
  Incomplete Transport: A previous transport operation did not complete successfully, leaving the request in a locked state.
  System Issues: There may be issues with the transport management system or database locks that are causing the request to be locked.
  
  Solutions:
  
  
  Check Lock Status:
  
  Use transaction code SM12 to check for locks on the transport request. You can filter by the transport request number to see if it is locked by another user.
  If you find that the request is locked by a user who is no longer active, you can delete the lock entry (if you have the necessary authorizations).
  
  
  
  Wait for Release:
  
  If another user is legitimately working on the request, you may need to wait until they have completed their work and released the lock.
  
  
  
  Transport Management:
  
  Ensure that the transport management system is functioning correctly. You can check the transport logs for any errors or issues that may have caused the lock.
  
  
  
  Restart Transport Process:
  
  If the transport request is stuck due to an incomplete operation, you may need to restart the transport process or, in some cases, delete and recreate the transport request.
  
  
  
  Contact Basis Team:
  
  If you are unable to resolve the issue, it may be necessary to contact your SAP Basis team for assistance. They can help investigate the issue further and may have tools to unlock the request if needed.
