Methods of the Local Controller Interface 

 All methods that can be changed - that is, methods that can be implemented by the application developer - are listed on the Methods tab of each controller. When double-clicking the method name, you switch to an ABAP Editor which enables you to implement the source code.

 

In addition to the changeable methods, the local interface of each controller provides several methods which can be used but whose implementations cannot be edited by the application developer. It depends on the type and the implementation state of a controller when these methods are available in the interface.

 Since all methods of this group cannot be changed, they are not displayed on the Methods tab of the corresponding controller. However, you can display the existing method by double-clicking the reference type IF_.................. of the attribute WD_THIS on the Attributes tab.
