  Authorization Issues: The user attempting to delete the model may not have the necessary authorizations to perform the delete operation.
  
  
  Technical Issues: There could be underlying technical issues, such as database locks or inconsistencies in the metadata.

  Solutions:
  
  
  Check Active Services: Verify if the model version is being used by any active OData services. If it is, you will need to deactivate those services before attempting to delete the model version.

  Validate Model and Version: Double-check the model name and version number you are trying to delete. Ensure that they are correct and that the model/version exists in the system.
  
  
  Use Transaction /IWFND/MAINT_SERVICE: Navigate to the transaction /IWFND/MAINT_SERVICE to manage your OData services. You can check the status of the model and see if there are any dependencies.
