• What is the cause and solution for SAP error message /SCWM/DELIVERY355 - Own lock owner: &1 &2 &3 ?

  The SAP error message /SCWM/DELIVERY355 Own lock owner: &1 &2 &3 typically occurs in the context of the SAP Extended Warehouse Management (EWM) module. This error indicates that a particular object (like a delivery or a warehouse task) is currently locked by another process or user, preventing the current operation from proceeding.
  Cause:
  
  Locking Mechanism: SAP uses a locking mechanism to prevent data inconsistencies. When a user or process is working on a specific object, it locks that object to ensure that no other process can modify it simultaneously.
  Long-running Transactions: If a transaction takes too long to complete, it may hold onto the lock longer than expected, causing other processes to encounter this error.
  Concurrent Access: Multiple users or processes trying to access the same object at the same time can lead to this error.
  System Performance Issues: If the system is slow or experiencing performance issues, locks may not be released in a timely manner.
  
  Solution:
  
  Identify the Lock Owner: The error message provides information about the lock owner (indicated by &1, &2, &3). You can use transaction SM12 to view the locks in the system and identify which user or process is holding the lock.
  Wait and Retry: If the lock is held by a legitimate process, you may need to wait for that process to complete and then retry your operation.
  Terminate the Lock: If you determine that the lock is no longer needed (for example, if the user has logged off or the process has failed), you can manually delete the lock using transaction SM12. However, be cautious with this approach, as it can lead to data inconsistencies if the process is still active.
  Optimize Processes: Review the processes that are causing locks to ensure they are optimized and not holding locks longer than necessary.
  Check for System Issues: If this error occurs frequently, it may indicate underlying system performance issues that need to be addressed.
  
  Related Information:
  
  Transaction Codes:

  SM21: To check system logs for any related errors or warnings.
  ST22: To check for dumps that might indicate underlying issues.
  
  
  Documentation: Refer to SAP Help documentation for Extended Warehouse Management for more details on locking mechanisms and best practices.
  Support: If the issue persists, consider reaching out to SAP support for further assistance, especially if it impacts business operations.
