What if you want to restrict the Entities that are exposed? What if you want to build a ODATA API that does a lookup from 2 Backend APIs ( Unified Entities ) with restricted fields? Welcome to the world of Custom Entities on SAP Graph on Integration Suite. As the name implies, you can define Custom entities on SAP Graph and expose them to your API consumers.
