  Check Existing Versions: Verify the existing versions of the object in question. You can do this by navigating to the relevant transaction or using the appropriate report to list existing versions.
  Delete or Modify Existing Version: If a duplicate version is found and is not needed, consider deleting it or modifying it as necessary. Ensure that you have the appropriate authorizations to perform these actions.
