MERGE operation on xsodata service officially supported?

Hi experts,

I am working on an SAP HANA SPS10 (1.00.102.04) system to create an xsodata service on top of a HANA CDS table. This is working fine:

CDS definition:

type Name : String(80);

entity Address {

          key id : Integer;

          street : Name;

          number : Integer;

          zipCode : String(30);

          city : Name;

          countryCode : String(2);

};

xsodata:

service {

  "Address" as "Address";

}

I am consuming the OData service through an SAPUI5 OData model:

     var oModel = new sap.ui.model.odata.ODataModel("test.xsodata");

Next, I am updating the table through a PUT request, which is also working fine:

oModel.update("/Address(1)", {id:1,street:"test"},number:1,zipCode:"test",city:"test",countryCode:"NL");

Finally, I tried to trigger a MERGE request to do a differential update on the table:

oModel.update("/Address(1)", {street:"test2"}, {merge:true});

To my surprise this worked without issues, as in earlier revisions this actually returned an error. However, I cannot find anything in the SAP HANA documentation / release notes about this feature? Can you let me know if MERGE is officially supported by SAP?

Thanks,

Matthijs
