Dear Experts,

soon or later SAP Netweaver GateWay will support OData v4. From backend developer perspective, is there any adjustment requirement of the services of type "SAP Standard Annotations" implemented in SEGW ? Does something special needed, when for example the UI5 (sap/ui/model/odata/v4/ODataModel or other REST clients start sending request using protocol version 4 ?
I'm interested in the backend aspects, because the UI5 implementation is known different already.
Thank you, Attila

Hi Attila,

SAP Gateway has started to support OData v4 with SAP NetWeaver 750 SP04.

OData v2 services cannot be "adjusted" so that they support OData v4.

Instead you have to create a new service in SEGW using project type "OData v4".

You may be able to reuse parts of your coding that you have created but it will not be possible to perform a simple "cut and paste" since the interfaces of the OData v4 runtime have changed compared to the OData v2 framework.

The documentation can be found here:
