Adding Model References 

Since you can create more than one WD model for a WD project at designtime, you have to define a model usage for the reference. This reference selects the corresponding service API at runtime to be the valid one for running the application.

Prerequisites

●      You have created a WD project.

●      You have defined the WD model.

●      A WD component is available for which you can define the model reference.

Procedure

       1.      In the Web Dynpro Explorer view, choose the context menu entry Add on the Used Models node of the WD component.

       2.      Choose one of the models you already had defined.

Result

In the Web Dynpro Explorer view, the model reference is displayed as a logical application unit of the Used Models subnode.
