Controller Properties

Controller Usage

Using Controllers of the Component Currently Being Processed

You can use already existing context structures or methods of other controllers of the component that is currently being processed within the controller that is currently being processed. The prerequisite for this is that you have created a controller usage on the Properties tab page for the controller that is currently being processed. You can use all global controllers of a component, that is, for customer or component controllers, for such a usage.

To create a controller usage in a controller, on the Properties tab page select the Create function to the top-left of the table. All available controllers will be displayed in a new window.

Using the Interface Controller of an External Component

The functions of interface controllers can be used not just in the component (because of its global ABAP interface) in which the controller was created.

By declaring a corresponding usage, you can also use the interface controller of an external component within the component that you processed.

To be able to select the interface controller of an external component to use it, first of all you have to declare a component usage.
