If a request is successful, warnings and success messages can be returned to the consumer in the new HTTP header SAP-Message. The format of the messages can be either set by the URL option format=json or in case of a modifying request with an empty response by using the request header Accept: application/json.
Example: http://<server>:<port>/sap/opu/odata/IWBEP/TEA_TEST_APPLICATION/Teams('TEAM_03')?$format=json
