The Custom CDS View app can be used to create customized value helps for custom business object fields of type Association to Business Object.

The value help view needs to have the associated custom business object as primary data source.

◉ You have used the associated custom business object view as Primary Data Source in the Custom CDS Views app.

Process Steps

◉ Select the type Association to Business Object and enter the following information:

    ◉ Business Object: Enter the technical name of the custom business object you want to associate.

    ◉ Value Help View: The automatically created value help view is selected automatically. If you want to use a customized value help, enter the technical name of the custom CDS view you have created in the Custom CDS Views app or use the value help to see all custom CDS views which use the business object as primary data source. The value help view is pre filled automatically for standard business objects.
