capire - Working with CDS Models (cloud.sap)
Dear Team,
I have an existing CDS service with the below definition. We can see that Publisher is a mandatory attribute as defined in 'BookService.BookServiceWD'.
As part of some new developments under a feature toggle, I want to remove the mandatory attribute from the Publisher field.
This attribute should be mandatory without the feature toggle and with the feature toggle it should be non-mandatory.
How could we go about implementing something like this ? If there is any sample reference, could you please share. Thanks.
using com.sap.test.datamodel as books_dm from '../db/data-model';
@cds.query.limit: { default: 50, max: 50 }
service BookService {
@readonly
entity Books as projection on books_dm.Books;
@odata.draft.enabled
entity BookServiceWD as projection on books_dm.Books;
@readonly
entity Publisher as projection on books_dm.Publisher;
};
annotate BookService.BookServiceWD with {
@mandatory
Publisher @(Common : {ValueList : {
SearchSupported : false,
Label : '{i18n>SelPublisher}',
CollectionPath : 'Publisher',
Parameters : [
{
$Type : 'Common.ValueListParameterInOut',
LocalDataProperty : Publisher,
ValueListProperty : 'Publisher' },
{
$Type : 'Common.ValueListParameterDisplayOnly',
ValueListProperty : 'PublisherName'
}
]
}});
};
