• What is the cause and solution for SAP error message CNV_OM_MWBGEN028 - Object &1: locked for (re-)generation - skipping. ?

  The SAP error message CNV_OM_MWBGEN028 indicates that a specific object (denoted as &1) is locked for (re-)generation, which means that the system cannot proceed with the operation because the object is currently in use or locked by another process. This is commonly encountered during data migration or conversion processes, particularly when using the SAP Conversion Tools.
  Cause:
  
  Object Locking: The object is locked by another user or process. This can happen if another session is currently modifying or using the object.
  Incomplete Previous Process: A previous operation that involved the object may not have completed successfully, leaving it in a locked state.
  System Configuration: There may be configuration settings that enforce locking mechanisms for certain objects during migration processes.
  
  Solution:
  
  
  Check Object Lock: Use transaction code SM12 to check for locks on the object. You can look for the specific object name and see if it is locked by another user or process.
  
  If you find a lock, you can either wait for the other process to complete or, if appropriate, you can delete the lock (ensure that it is safe to do so).
  
  
  
  Review Active Sessions: Check if there are any active sessions that might be using the object. You can use transaction code SM66 to monitor active processes in the system.
  
  
  Restart the Process: If the previous process that was using the object has failed or is no longer running, you may need to restart the migration or conversion process.
  
  
  Check for Background Jobs: Sometimes, background jobs may hold locks on objects. Use transaction code SM37 to check for any background jobs that might be running and holding locks.
  
  
  Consult Documentation: Review the documentation for the specific migration or conversion tool you are using to see if there are any specific recommendations or known issues related to object locking.
  
  
  Contact SAP Support: If the issue persists and you cannot identify the cause, consider reaching out to SAP support for further assistance.
