Accept
header in the request specifies a media type that the OData service can handle (e.g.,application/json
,application/xml
).- Review OData Service Configuration: Verify that the OData service is correctly configured to support the requested media types. This can be done in the SAP Gateway Service Builder (transaction code

SAP messages fall into 3 different categories: Error messages
(message type = E), Warnings (W) or Informational (I) messages.
An error message will prevent you from continuing your work - it is a hard stop and you need to fix the error before you can proceed. A warning message will stop your work, however, you can then bypass the warning by pressing the Enter key on your keyboard. That said, it is still good practice to investigate the cause of the warning message and address it. An information message will not stop your work and is truly just for informational purposes.
