Hi,

You have many documents in SDN you can go through them, you will be having indepth knowledge on them. In brief, the following is the definitions

Custom controllers

Custom controllers are used to encapsulate units of functionality that are shared by several controllers

and require no direct user interaction. Such controllers therefore have no visual interface.

For instance, a custom controller could be used, when a BAPI is called, and the information returned

requires some sort of intermediate processing before it can be displayed.

Before implementing a custom controller, consider carefully whether its presence will simplify or

complicate the overall architecture of your application. Custom controllers should only be added in

situations that will optimize or simplify the architecture of your application.

component controller

The component controller is a that is automatically created when a

component is created. It is this controller that drives the functionality of the entire component.

The interface(s) that this single component presents to either the Web Dynpro Framework or the

embedding controller are defined as . There is a one to one relationship between

a component interface view and a component window.

Interface Controller

This controller is also a special custom controller. This is the only custom controller visible to other

components.
