Web Dynpro Application
Another important
task of the window is to establish the connection between the structured view
group (or at least one individual view) and a URL that can be called by the
user. The window is also a unit called by a user using a
Web Dynpro
application. In
general, only one view is displayed on the screen at a time. In the simplest
case, the Web Dynpro application calls the view specified as the start view
(default) within the window. The user can navigate from this
start view to a subsequent view.
The Web Dynpro
application is an independent object in the object list of the ABAP Workbench.
For more information about creating and editing an application, see the tools
manual in the section
Web Dynpro
Application. For more information about the URL, see the section URL of a Web Dynpro
Application.

When you create a Web Dynpro
application, an appropriate node is automatically created in the ICF tree (see
the section Initial
Configuration Settings in
Web Dynpro for ABAP
Configuration).
The connection between a Web Dynpro window and a Web Dynpro application is established by the interface view of a window. Exactly one interface view is automatically assigned to each window of a component and this interface view contains a default plug by default.

You can
display each interface
view in the ABAP Workbench.
The interface views
do not only connect the application to the window, but they and their plugs
have several more functions. As a part of the
component
interface, they are also used when multiple components are to communicate
with each other. This is the reason why they are described in more detail in
several sections of the second part of the programming guide.
