Displaying and Defining the Interface Controller

Interface Controller of a Component

The interface controller of a Web Dynpro component contains all context nodes, events and methods of the component controller to which you assigned the Interface addition in the Controller Editor. These parts can be displayed in the interface controller view, although you cannot edit them here.

Interface Controller of a Component Interface

A Web Dynpro component interface can be created independently and defined so that it can be implemented later in any components (see Working with Web Dynpro Component Interfaces ).

That is why in this case you can define the context nodes, methods and events you require in the interface controller view. The relevant implementation then takes place in the component controller of the implementing component.
