Hello All,
Sap_message property in oData v4 APIs for SAP S/4Hana Cloud exposed on API HUB
Query: there are some OData v4 APIs for SAP S/4Hana Cloud which supports this sap_message property. I would like to understand how to use it. I am using postman to test this.
Based on the information provided by SAP, the sap_message header contains sap server messages.

When I execute the Get operation on the Bank API, I get empty sap_messages.

For some reason, the sap has included this property for creating operation payload format and updating operation format as well

Does this mean this property is updatable and creatable?
I tried updating it but received the below error

Based on my analysis, the sap_message is supposed to come in case of a successful response only.
So basically, the question here is, in case of creating or updating an operation, can this property be part of the request body?
