Facing errors while creating a odata service consuming a calculation view.

HI All.

I am pretty new to XS , I am trying to create an ODATA service from a calculation view . But whenever I try to activate the service I get the following error

"Missing specification of keys for view "demo::CV_PASS1".

    An OData service must have a key specification as a unique URL for each record must be generated. For table sources XSODATA uses the key specification of the table itself as the source of the OData key. Calculation views, on the other hand, have no key structure. You must either specify the key columns within the XSODATA document itself

    service {


    as "Buyer"



    Or use the KEYS GENERATE LOCAL option to have the framework generate a key for you (useful when you have aggregation):

    service namespace "sap.hana.democontent.epmNext" {


    as "SalesByCountry" with ("COUNTRY", "TOTAL_SALES", "SALES", "SHARE_SALES")

    keys generate local "ID"

    aggregates always;
