Update Components: If there is a version mismatch, consider updating your components to ensure compatibility. This may involve:
- Updating the SAP Fiori elements version.
- Ensuring that your SAP backend is up to date.
Test the Service: After making changes, test the OData service using tools like Postman or the SAP Gateway Client (transaction code /IWFND/GW_CLIENT) to ensure that the annotations are now present and correctly defined.
