SAP Cloud for Customer offers a development environment (SAP Cloud Applications Studio) which allows to extend the solution (new Business logic, new UIs, …), which also allows the creation of new interfaces.
New interfaces could be created both for existing Business Objects (Accounts, Contacts, Opportunities, …) and also for Custom Business objects (which is the
case in this video, where we are creating interfaces to a custom Business Object “Projects”).
From SAP Cloud Applications Studio you can select the Business Object and with right click you can request to “Create Service Integration” to create a Web Service interface.
Then you’ll select the object or part of it which you will expose in that Interface, and for each operation of the interface (Create, Read, Update, Query, …) you’ll
specify the fields to expose in each of them.
