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 on creating and editing an application, refer to the tools manual in chapter Web Dynpro Application. For more information on the URL, refer to chapter URL of a Web Dynpro Application.
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.
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 chapters of the second part of the programming manual.
