• What is the cause and solution for SAP error message /SMB/CM_CNV_LCK002 - Live Conversion running indicator is already exist ?

  The SAP error message /SMB/CM_CNV_LCK002 Live Conversion running indicator already exists typically occurs during a data migration or conversion process, particularly when using the SAP S/4HANA Migration Cockpit or similar tools. This error indicates that there is already an active conversion process running, which prevents a new conversion from starting.
  Cause:
  
  Concurrent Processes: The most common cause is that a previous live conversion process is still running or has not been properly terminated.
  Locking Mechanism: SAP uses a locking mechanism to prevent multiple instances of the same conversion process from running simultaneously. If a process is still active, it will block any new attempts to start a conversion.
  System Errors: Sometimes, system errors or crashes can leave a lock in place, indicating that a conversion is still in progress when it is not.
  
  Solution:
  
  
  Check Active Processes: 
  
  Use transaction codes like SM37 to check for any active background jobs related to the conversion process. If you find any, you may need to wait for them to complete or terminate them if they are stuck.
  
  
  
  Release Locks:
  
  If you determine that no conversion is actually running, you can manually release the lock. This can be done using transaction SM12 to delete the lock entries related to the conversion process.
  Look for entries with the lock object /SMB/CM_CNV_LCK and delete them if they are no longer needed.
  
  
  
  Restart the Process:
  
  After ensuring that no other conversion processes are running and that locks have been cleared, you can attempt to restart the live conversion process.
  
  
  
  Check Logs:
  
  Review the logs for any errors or warnings that might indicate why the previous process did not complete successfully. This can provide insights into whether there are underlying issues that need to be addressed.
  
  
  
  System Restart:
  
  In some cases, a system restart may be necessary to clear any lingering locks or processes that are not visible through standard transaction codes.
