• What is the cause and solution for SAP error message /SSB/CORE820 - Object already locked under request &1 in client &2 ?

  The SAP error message /SSB/CORE820 Object already locked under request &1 in client &2 typically indicates that a specific object (such as a transport request or a development object) is currently locked by another user or process in the specified client. This can happen during transport operations, development activities, or when trying to modify an object that is already being edited or transported by someone else.
  Cause:
  
  Concurrent Access: Another user or process is currently working on the same object, leading to a lock.
  Transport Request: The object is part of a transport request that is currently being processed or has not been released.
  System Lock: The system may have a lock due to a previous operation that did not complete successfully.
  
  Solution:
  
  
  Identify the Lock:
  
  Use transaction code SM12 to check for locks. You can filter by the object name or user to find out who is holding the lock.
  Look for the transport request number mentioned in the error message.
  
  
  
  Release the Lock:
  
  If you have the necessary authorizations, you can manually delete the lock entry in SM12. However, be cautious with this approach, as it may lead to data inconsistency if the other user is still working on the object.
  If the lock is held by another user, communicate with them to see if they can release the lock or if they are done with their changes.
  
  
  
  Wait for Completion:
  
  If the lock is due to a transport request that is being processed, you may need to wait until the transport is completed.
  
  
  
  Check for Background Jobs:
  
  Sometimes, background jobs may hold locks. Check transaction SM37 to see if there are any jobs that might be causing the lock.
  
  
  
  Review Transport Management:
  
  Ensure that the transport management system is functioning correctly and that there are no issues with the transport routes or requests.
