• What is the cause and solution for SAP error message /SCWM/RETURNS002 - Returns delivery locked by other users ?

  The SAP error message /SCWM/RETURNS002 indicates that a returns delivery is locked by other users. This typically occurs in the SAP Extended Warehouse Management (EWM) module when multiple users attempt to access or modify the same returns delivery document simultaneously. Here’s a breakdown of the cause, potential solutions, and related information:
  Cause:
  
  Concurrent Access: Another user is currently processing the returns delivery, which locks the document to prevent data inconsistencies.
  Long-running Transactions: A user may have a long-running transaction that is holding the lock on the returns delivery.
  System Configuration: Certain configurations in the system may lead to locks being held longer than necessary.
  
  Solutions:
  
  
  Wait and Retry: If the lock is temporary, waiting for the other user to complete their transaction may resolve the issue. You can try to access the returns delivery again after some time.
  
  
  Identify the Lock: Use transaction code SM12 to check for locks in the system. You can filter by the user ID or the object type to find out which user is holding the lock on the returns delivery.
  
  If you find a lock that seems to be unnecessary or is held for too long, you can contact the user to ask them to release it.
  
  
  
  Release the Lock: If you have the necessary authorizations, you can manually delete the lock entry in SM12. However, this should be done with caution, as it may lead to data inconsistencies if the other user is still working on the document.
  
  
  Check for Background Jobs: Sometimes, background jobs may hold locks. Check if there are any background processes that might be affecting the returns delivery.
  
  
  Review System Performance: If locks are a frequent issue, it may be worth reviewing system performance and user access patterns to identify any underlying issues that could be optimized.
  
  
  Consult with Basis Team: If the problem persists, it may be beneficial to consult with your SAP Basis team to investigate any system-level issues that could be causing excessive locking.
  
  
  Related Information:
  
  Lock Management: Understanding how SAP handles locks can help in troubleshooting. SAP uses a locking mechanism to ensure data integrity, and locks can be at various levels (e.g., table level, object level).
  User Training: Ensure that users are trained on how to properly handle returns deliveries and understand the implications of concurrent access.
  System Configuration: Review the configuration settings related to locking behavior in your SAP system, as these can sometimes be adjusted to reduce locking issues.
  
  By following these steps, you should be able to address the /SCWM/RETURNS002 error and minimize its occurrence in the future.
