How to know which version of Odata protocol (v2 or v4) is supported in Gateway?

[p619793]

I know the OData version depends on the basis release of the depends on the underlying SAP Basis release of your SAP Business Suite or S/4 HANA system?

The odata version of an existing Odata service can also be known from its metadata by the tag <edmx:DataServices>.

Is there any way to know beforehand by the system details which versions of OData are supported in my system?

Following thread mentions about this but now one can implment both v2 and v4 if both are supported if I understand it right.

Easier way could be to check T-code /IWFND/V4_ADMIN (or any specific to V4) for V4 support and /IWFND/MAINT_SERVICE for V2

we hade SAP_GWFND installed

version release:740

SP level: 20

Then yours would have OData V2 installed.

Check the metadata in t-code "/n/iwfnd/gw_client" by adding $metadata to the URI, you can find the odata version
