Smart SAP Assistant

• What is the cause and solution for SAP error message ATO_CUSTOMER836 - All changes locked by user &1. ?

  The SAP error message ATO_CUSTOMER836, which states "All changes locked by user &1," typically indicates that a user has locked the object or data you are trying to modify. This can happen in various scenarios, such as when a user is currently editing a record or has not properly released a lock after completing their work.
  Cause:
  
  
  User Lock: The user identified by &1 has an active lock on the object you are trying to change. This could be due to:
  
  The user is currently editing the object.
  The user has not released the lock after completing their changes.
  A previous session did not close properly, leaving the lock active.
  
  
  
  System Lock: Sometimes, system-level locks can occur due to background jobs or processes that are running and have not yet completed.
  
  
  Solution:
  
  
  Identify the Locking User: 
  
  Use transaction code SM12 to view the locks in the system. You can filter by the user ID to see what objects are locked by that user.
  
  
  
  Release the Lock:
  
  If you have the necessary authorizations, you can manually delete the lock entries in SM12. Be cautious when doing this, as it may disrupt the work of the user who has the lock.
  
  
  
  Contact the User: 
  
  If you identify the user who has the lock, you can contact them to see if they can release the lock themselves. They may need to log out and log back in or simply navigate away from the object they are editing.
  
  
  
  Check for Background Jobs: 
  
  Use transaction code SM37 to check if there are any background jobs that might be holding locks on the object. If so, you may need to wait for those jobs to complete.
  
  
  
  System Restart: 
  
  In rare cases, if the locks are persistent and cannot be resolved through the above methods, a system restart may be necessary. This should be done with caution and typically requires coordination with your SAP Basis team.
  
  
  
  Related Information:

  Performance Monitoring: Regularly monitor system performance and lock situations to prevent bottlenecks caused by locked objects.
  
  If the issue persists after trying the above solutions, it may be beneficial to consult with your SAP Basis team or SAP support for further assistance.
