  The SAP error message CNV_OM_MWBGEN023 typically occurs during the data migration process, particularly when using the SAP Migration Workbench (MWB). This error indicates that an object (like a table or a data structure) already exists in the target system but has been modified in some way, leading the migration process to skip it to avoid overwriting or conflicting changes.
  Cause:
  
  Existing Object: The object you are trying to migrate already exists in the target system.
  Changes Detected: The existing object has been changed since it was last migrated or since the migration plan was created.
  Data Integrity: The system is designed to prevent overwriting existing data that may have been modified to maintain data integrity.
  
  Solution:
  
  Review Existing Objects: Check the existing object in the target system to understand what changes have been made. You may need to compare the structure or data of the existing object with the one you are trying to migrate.
  Decide on Action:
  
  Skip Migration: If the existing object is correct and does not need to be updated, you can choose to skip the migration for that object.
  Update Existing Object: If the changes in the source object are necessary, you may need to manually update the existing object in the target system to match the source before re-running the migration.
  Delete and Recreate: If appropriate, you could delete the existing object in the target system and then re-run the migration. Be cautious with this approach as it may lead to data loss.
  
  
  Adjust Migration Plan: If you frequently encounter this issue, consider adjusting your migration plan to account for existing objects and their changes.
