Hi Virinchy, Thank you for reply.
I could confirm OData version at the Headers Tab in the Network at console level of browser.
But I can't register GWSAMPLE_BASIC on Hana Cloud Integration Data Service.

I look like service document format of GWSAMPLE_BASIC is version 4 why it can't register.
There are <app:workspace> and <app:collection> tags in GWSAMPLE_BASIC, It's version4 format.
In version2, There aren't "app:xxxx" tags.
Please see this link. It's OData Service Document format of version 4.
Can you tell me your comment?
