• What is the cause and solution for SAP error message UACC079 - Node for object &1 is locked and cannot be deleted ?

  The SAP error message UACC079 indicates that a node (or object) in the system is locked and cannot be deleted. This typically occurs in the context of authorization objects, roles, or other configuration elements that are part of the SAP security framework.
  Cause:
  
  Lock Status: The object you are trying to delete is currently locked by another user or process. This can happen if someone else is editing the object or if a previous transaction did not complete successfully.
  Transport Requests: If the object is part of a transport request that is currently being processed, it may be locked until the transport is completed.
  Authorization Issues: The user attempting to delete the object may not have the necessary authorizations to perform the delete operation.
  System Configuration: Certain system configurations or settings may prevent the deletion of specific objects.
  
  Solution:
  
  Check Lock Status: Use transaction code SM12 to check for locks on the object. You can look for the user who has locked the object and coordinate with them to release the lock.
  Release Locks: If you have the necessary authorizations, you can manually delete the lock entries in SM12. However, be cautious when doing this, as it may affect other users.
  Transport Management: If the object is part of a transport request, ensure that the transport is completed or released before attempting to delete the object.
  Authorization Check: Verify that you have the necessary authorizations to delete the object. You may need to consult with your SAP security team to ensure you have the right permissions.
  Wait and Retry: If the lock is temporary (e.g., due to another user’s activity), you may need to wait for the other user to finish their work and then try again.
