• What is the cause and solution for SAP error message CNVMBT090 - RFC Destination &1 unlocked by user &2. ?

  The SAP error message CNVMBT090 indicates that an RFC (Remote Function Call) destination has been unlocked by a specific user. This typically occurs in the context of data migration or conversion processes, particularly when using the SAP Migration Cockpit or similar tools.
  Cause:
  
  User Locking: The RFC destination is locked by a user, which prevents other users or processes from accessing it. This can happen if a user is currently using the destination or if there was an error in a previous session that left the destination in a locked state.
  Session Timeout: If a user session times out or is terminated unexpectedly, it may leave the RFC destination in a locked state.
  Configuration Issues: There may be configuration issues with the RFC destination itself, such as incorrect settings or permissions.
  
  Solution:
  
  
  Unlock the RFC Destination:
  
  You can unlock the RFC destination by using transaction SM59 (RFC Destinations). Locate the relevant RFC destination and check its status. If it is locked, you may need to unlock it manually.
  Alternatively, you can ask the user who locked the destination to unlock it if they are still logged in.
  
  
  
  Check User Sessions:
  
  Use transaction SM04 to check active user sessions. If the user who locked the destination is still logged in, you may need to coordinate with them to resolve the issue.
  
  
  
  Review Logs:
  
  Check the system logs (transaction SM21) for any related errors or warnings that might provide more context about why the RFC destination was locked.
  
  
  
  Configuration Review:
  
  Ensure that the RFC destination is correctly configured. Verify the connection parameters, user authorizations, and any relevant settings.
  
  
  
  Restart the Process:
  
  If the issue persists, consider restarting the data migration or conversion process after resolving the locking issue.
