  The SAP error message "CNV_MBT260 Package &1 already exists" typically occurs during the execution of a migration or conversion process, particularly when using the SAP S/4HANA Migration Cockpit or similar tools. This error indicates that a package with the specified name already exists in the system, which can lead to conflicts or issues during the migration process.
  Cause:
  
  Duplicate Package: The most common cause of this error is that a package with the same name already exists in the system. This can happen if a previous migration attempt was not completed successfully, leaving behind remnants of the process.
  Incorrect Configuration: There may be a misconfiguration in the migration settings that leads to the creation of a package with a name that already exists.
  Concurrent Processes: If multiple migration processes are running simultaneously, they might attempt to create packages with the same name.
  
  Solution:
  
  
  Check Existing Packages: 
  
  Use transaction code SE80 or SE11 to check for existing packages in the system. Look for the package name indicated in the error message.

  Restart the Migration Process:
  
  After resolving the package conflict, restart the migration process to see if the error persists.
