Smart SAP Assistant

• What is the cause and solution for SAP error message DT653 - Object & already locked -> activation not performed ?

  The SAP error message DT653 ("Object & already locked -> activation not performed") typically occurs when you attempt to activate a transport request or an object that is already locked by another user or process. This can happen in various scenarios, such as when multiple users are working on the same object or when a previous activation process has not been completed.
  Cause:
  
  Concurrent Access: Another user or process is currently working on or has locked the object you are trying to activate.
  Incomplete Previous Activation: A previous activation attempt may have failed or not completed properly, leaving the object in a locked state.
  Transport Lock: The object may be part of a transport request that is currently being processed or has been left in a locked state.
  
  Solution:
  
  
  Check Lock Entries:
  
  Use transaction code SM12 to check for lock entries. You can filter by the object name or user to see if another user has locked the object.
  If you find a lock that is no longer needed, you can delete it (if you have the necessary authorizations).
  
  
  
  Wait and Retry:
  
  If another user is working on the object, it may be best to wait until they have completed their work and released the lock.
  
  
  
  Check Transport Requests:
  
  Use transaction code SE09 or SE10 to check the status of transport requests. Ensure that there are no pending requests that might be locking the object.
  
  
  
  Release Locks:
  
  If you determine that a lock is stale (e.g., due to a user session that has ended unexpectedly), you may need to release the lock manually using SM12.
  
  
  
  Check for Background Jobs:
  
  Sometimes, background jobs may hold locks on objects. Use transaction code SM37 to check for any running or completed jobs that might be related to the object.
  
  
  
  Consult Basis Team:
  
  If you are unable to resolve the issue, it may be necessary to consult your SAP Basis team for assistance. They can help identify any underlying issues or perform actions that require higher-level access.
