Calling a Web Dynpro Application Using Parameters 

Use

The URL parameters of a Web Dynpro application are defined by the main component.

The component’s window has an inbound plug. This inbound plug can have parameters, which have to be specified as URL parameters.

Default values that are overwritten by the URL parameters can be set in the application for these parameters. If neither a default value nor a URL parameter is specified, a runtime error is triggered.

Procedure

...

       1.      In the component, switch to the window editor.

Here you can change the predefined inbound plug or create a new inbound plug.

                            a.      Specify the plug as a startup plug (Start).

                            b.      The data type should be string since data conversion and data checking are currently not performed.

                            c.      Activate the component.

       2.      For the application, specify the component to be called, the window, and the startup plug. You can now specify the parameters.

Apart from the default parameters, the startup plug parameters are also available and can be assigned a default value. If no default value is specified, the parameters have to be specified as URL parameters when calling the application.

       3.      Call the application.

The URL parameter overwrites the application parameter.
