Hi Venkatesh,

When using Explicit Configuration it is possible to influence the appearance and behavior of a Web Dynpro component. These influences can be implemented through additional attributes in the context of a special custom controller - the Configuration Controller - where you can define attributes in the context of this controller. The storage of the attributes in the context of the configuration controller ensures that their values can be set or changed later on with the help of the Component Configurator. Furthermore, the processing of attributes must be explicitly programmed by the application developer in a controller method of the component.

Also check this Blog how to do custom configuration.

Hi Venkatesh,

Try going through the SAP documentation you will come across the desired information. The below lines are taken from 1 such source.

Custom controllers are optional controllers that must be defined by the developer. These controllers can be used to modularize the component content. For example, custom controllers can act as local controllers for some views, or they can be used to encapsulate the logic related to a certain model class (business logic).

This allows you to reduce the content of the component controller by populating sub-functions.

Custom controllers are optional. They have to be defined at design time and can be used to encapsulate sub-functions of the component controller. Multiple custom controllers can be defined in a component. Custom controllers are instantiated automatically by the Web Dynpro framework and the instantiation order is undefined; therefore, the coding in a custom controller should
