• What is the cause and solution for SAP error message GZ660 - Selected items are being processed by another user ?

  The SAP error message GZ660, which states "Selected items are being processed by another user," typically occurs in scenarios where multiple users are trying to access or modify the same data or document simultaneously. This is a common issue in environments where concurrent processing is allowed, and it can lead to data integrity problems if not managed properly.
  Cause:
  
  Concurrent Access: Another user is currently processing the same items or documents you are trying to access.
  Locking Mechanism: SAP uses a locking mechanism to prevent data inconsistencies. When one user is editing or processing an item, it gets locked for others.
  Long Running Transactions: If a transaction takes a long time to complete, it can lead to other users being unable to access the same items until the first transaction is finished.
  Background Jobs: Sometimes, background jobs may also lock items, preventing other users from accessing them.
  
  Solution:
  
  Wait and Retry: If the item is being processed by another user, the simplest solution is to wait for that user to complete their transaction and then try again.
  Check Lock Entries: Use transaction code SM12 to check for lock entries. You can see which user is holding the lock and the object being locked. If necessary, you can ask the user to release the lock or, if appropriate, you can delete the lock entry (with caution).
  Communicate with Users: If you are in a team environment, communicate with your colleagues to ensure that you are not trying to access the same items simultaneously.
  Review Background Jobs: Check if any background jobs are running that might be locking the items. You can use transaction code SM37 to monitor background jobs.
  Increase Timeout Settings: If this issue occurs frequently, consider reviewing and possibly increasing the timeout settings for transactions in your SAP system.
  System Configuration: Consult with your SAP Basis team to ensure that the system is configured correctly for concurrent processing.
