OData Service Troubleshooting for SAP Gateway

Common OData issues

When Fiori apps show errors, Gateway services are usually the root cause. Here is a checklist I follow:

1. Verify service activation and system alias
2. Check /IWFND/ERROR_LOG and /IWBEP/ERROR_LOG
3. Validate metadata and entity sets
4. Use /IWFND/GW_CLIENT for testing

Tips

Align backend data validation with the UI to avoid runtime surprises.
