• What is the cause and solution for SAP error message /SCWM/DELIVERY320 - Document (Warehouse task) &1 &2 &3 is locked by user &4 ?

  The SAP error message /SCWM/DELIVERY320 indicates that a warehouse task (WT) is locked by a user, which prevents other users from processing that task. This can occur in the SAP Extended Warehouse Management (EWM) module when a user is currently working on or has opened a warehouse task, and another user attempts to access or modify the same task.
  Cause:
  
  User Lock: The warehouse task is currently being processed by another user, which results in a lock on that task.
  Session Timeout: A user may have left a session open, causing the task to remain locked.
  System Error: Occasionally, system errors or crashes can lead to tasks being improperly locked.
  Long Processing Time: If a user is taking a long time to process a task, it may remain locked for an extended period.
  
  Solution:
  
  Wait and Retry: If the task is locked by another user, the simplest solution is to wait until that user has completed their work and released the lock.
  Identify the Locking User: Use transaction code SM12 to check for locks in the system. You can search for the specific warehouse task and see which user has it locked.
  Contact the User: If you identify the user who has the task locked, you can contact them to see if they can release the lock.
  Release the Lock: If the user is unavailable or the lock is no longer valid (e.g., due to a session timeout), an administrator can manually release the lock using transaction SM12. However, this should be done with caution to avoid data inconsistencies.
  Check for System Issues: If this issue occurs frequently, it may be worth investigating if there are underlying system issues or if the configuration needs to be adjusted.
