Navigation Modeler
Features
The Navigation Modeler is a graphical Web Dynpro tool of the SAP NetWeaver Developer Studio. It supports you when designing and implementing the user interface elements, views, navigation, and application entities involved in the navigation. The view that displays the work area of the Navigation Modeler, and within which the individual elements are displayed, is the Diagram View.
The Application Modeler provides support when you create and change the following entities of a Web Dynpro application; as well as an introduction to the terminology, the descriptions also feature a categorization of the entities in the architecture of Web Dynpro applications.
· View Set
· View
· Plug
· Link
You can create several views or view sets for a Web Dynpro application. The editing area of the Navigation Modeler expands automatically if there is insufficient space for the display. The Overview tab is available for complex applications. It allows you to navigate within the graphical tool: Drag the viewer to the position where you want to edit.

The size of the Navigation Modeler editor is then increased so that it fills the entire Web Dynpro perspective window. To revert to the original size, double-click the Diagram View bar again.
Views, view sets, plugs, and links must only be created using the Navigation Modeler. Use the Web Dynpro Explorer to display defined Web Dynpro entities. To create the views you can also use the Data Modeler; the main focus of this tool is on data flow definition.
