• 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)
