Can you please help me understand how to add annotation(SAP:Filterable) to a property in oData Service.
data-model.cds -- > I have created all the data models
.xsodata -- > I have created an xsodata service
Now , I would like to create Smart Variant for a Page and in order to use it , I guess, some properties should have sap:filterable property in order to show the field Smart Filter bar.
At the moment, my XSODATA Service is having parameters as shown below
Type="Edm.String" Nullable="false" MaxLength="4"
I would like to add sap:filterable=true as well.
