• What is the cause and solution for SAP error message CM_SUB026 - Source being edited by user &; unlocked data is copied ?

  The SAP error message CM_SUB026 indicates that a source (such as a material, document, or other data object) is currently being edited by another user. This means that the system has detected that the data is locked for editing, and as a result, the operation you are trying to perform cannot be completed because the data is not available for modification.
  Cause:
  
  Concurrent Editing: Another user is currently editing the same source data, which locks the data for other users.
  Session Timeout: A previous session may not have been properly closed, leaving the data in a locked state.
  System Configuration: Certain configurations in the SAP system may lead to data being locked for longer periods than necessary.
  
  Solution:
  
  Wait and Retry: If another user is editing the data, the simplest solution is to wait until they finish and then try your operation again.
  Check User Sessions: Use transaction codes like SM12 (to view and manage lock entries) to check if there are any active sessions that are locking the data. If you find a session that is no longer active, you may be able to delete the lock entry (if you have the necessary permissions).
  Communicate with Users: If you know who is editing the data, you can communicate with them to see if they can save their changes and release the lock.
  Review System Settings: If this issue occurs frequently, it may be worth reviewing the system settings or configurations related to data locking and editing to ensure they are optimized for your business processes.
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with transaction codes like SM12 (to view lock entries) and SM21 (to check system logs) for troubleshooting.
  User Roles and Permissions: Ensure that users have the appropriate roles and permissions to edit the data and manage locks.
  SAP Notes: Check SAP Notes for any known issues or patches related to this error message. SAP frequently updates its knowledge base with solutions to common problems.
