Smart SAP Assistant

• What is the cause and solution for SAP error message SQLRQW020 - Customizing already locked by & ?

  The SAP error message SQLRQW020 indicates that a customizing object is already locked by another user or process. This typically occurs when multiple users or processes attempt to modify the same customizing settings simultaneously, leading to a conflict.
  Cause:
  
  Concurrent Access: Another user or session is currently editing the same customizing object.
  Long-Running Transactions: A transaction that takes a long time to complete may hold the lock longer than expected.
  System Issues: Sometimes, system issues or bugs can lead to locks not being released properly.
  
  Solution:
  
  
  Wait and Retry: If the lock is held by another user, the simplest solution is to wait until the other user has finished their work and released the lock. You can then retry your action.
  
  
  Identify the Lock: Use transaction code SM12 to check for locks. You can see which user or session is holding the lock. If you have the necessary authorizations, you can also unlock the object, but this should be done with caution to avoid data inconsistency.
  
  
  Communicate with Users: If you identify that a specific user is holding the lock, you may want to communicate with them to understand their needs and coordinate the changes.
  
  
  Check for Background Jobs: Sometimes, background jobs may hold locks. You can check transaction SM37 to see if any background jobs are running that might be causing the lock.
  
  
  System Restart: In rare cases, if the lock persists and cannot be resolved, a system restart may be necessary to clear any stale locks. This should be done as a last resort and typically requires coordination with your SAP Basis team.
