Referencing a Model 
The Web Dynpro Component provides interfaces for the data flow between the various Web Dynpro entities. To reference a Model you must define a model usage.
You have already created the Web Dynpro component and the model to be referenced.
To define a model usage, proceed as follows:
...
1.
In the Web Dynpro
Explorer view, choose the context menu entry
Add for the node
Used Models.
2. Choose one of the models already defined from the dialog box and choose OK to close. Save the changes.
In the Web Dynpro
Explorer, the referenced model is displayed as an element of the subnode
Used Models.
