In which controller type can you embed a service call?

The correct response is based on the functions and purposes of the various controller types within the SAP environment. A component controller is specifically designed to handle the logic for an entire view or a portion of the application at a reusable component level. It is capable of managing service calls, where data can be fetched or manipulated by invoking services.

By utilizing a component controller, you can effectively encapsulate the logic required for making service calls, ensuring that the component remains modular and reusable throughout the application. This approach promotes a clean architecture where service interactions are contained, thereby simplifying maintenance and testing.

In contrast, an interface controller primarily acts as a conduit between the user interface and the application, managing the navigation and user interactions without engaging in service calls directly. The view controller is mainly focused on managing the presentation logic and user interaction but does not encapsulate service call logic. The configuration controller deals with application configurations and settings, rather than service operations.

Thus, the component controller is the appropriate choice for embedding service calls due to its ability to manage both the internal logic of the component and its interaction with external services, making it the most suitable option in this context.
