Calling a Web Dynpro Application

In a Web Dynpro application, the component 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.

 

To create a new inbound plug, specify plug as a startup and data type should be a string. Activate the component.
