OData: Resource not found for segment

Resource not found for segment

An SAP Gateway OData request returns an error such as "Resource not found for segment ..." and the request cannot be resolved to the expected entity/navigation path.

Quick answer

Most likely cause
The URL contains the wrong entity set or navigation-property name.
Check first
Open the service $metadata and verify the exact EntitySet and navigation-property names.
First resolution step
Compare every URL segment against the current $metadata document.

Likely root causes

  1. The URL contains the wrong entity set or navigation-property name.
  2. The service metadata changed but the client still calls an old path.
  3. The service is active, but the requested segment is not exposed in the current metadata/model.

What to inspect

  1. Open the service $metadata and verify the exact EntitySet and navigation-property names.
  2. /IWFND/ERROR_LOG — inspect the Gateway error at the failing timestamp.
  3. /IWFND/GW_CLIENT — reproduce the request directly in Gateway.
  4. SEGW or service implementation — verify model exposure for custom services.

Resolution path

  1. Compare every URL segment against the current $metadata document.
  2. Correct the client URL or the service model depending on which side is wrong.
  3. Refresh/re-register metadata only when required by the deployment process.
  4. Retest in /IWFND/GW_CLIENT before changing the consuming application.
