• What is the cause and solution for SAP error message /SMB/SC_MAIN095 - Selection Set &1 is locked by user &2 ?

  The SAP error message /SMB/SC_MAIN095 Selection Set &1 is locked by user &2 indicates that a selection set (a predefined set of criteria for data selection) is currently locked by another user. This typically occurs in scenarios where multiple users are trying to access or modify the same selection set simultaneously.
  Cause:
  
  Concurrent Access: Another user is currently using or has locked the selection set for editing.
  Session Timeout: A previous session may not have released the lock due to a timeout or an unexpected termination.
  System Error: Occasionally, system errors or bugs can lead to locks not being released properly.
  
  Solution:
  
  
  Wait and Retry: If the selection set is locked by another user, the simplest solution is to wait until that user has finished their work and released the lock. You can then try to access the selection set again.
  
  
  Identify the Locking User: If you need immediate access, you can identify the user who has locked the selection set. You can do this by:
  
  Using transaction code SM12 to view and manage locks. You can search for the specific selection set and see which user has it locked.
  If necessary, you can contact the user to ask them to release the lock.
  
  
  
  Release the Lock: If the locking user is unavailable or if the lock is stale (e.g., due to a session crash), you may need to release the lock manually:
  
  In transaction SM12, find the lock entry and delete it. Be cautious with this approach, as it may disrupt the work of the user who has the lock.
  
  
  
  Check for System Issues: If this error occurs frequently, it may indicate a system issue. In such cases, consult with your SAP Basis team to investigate potential problems with the locking mechanism or session management.
