[ABAP] Service Calls in a Web Dynpro Application

Service Calls in a Web Dynpro Application

Use

A service call is used to call an existing function module or methods of an existing class within a Web Dynpro component. This is particularly useful with reference to assistance classes or proxy classes of Web services.

Prerequisites

If you want to use the service call to include an existing function module in your Web Dynpro application, you can access function modules that are available in the system.

Features

To simplify the creation process, you have an extensive wizard at your disposal. With the help of this wizard, all the required context elements are automatically generated in a controller you have selected. Also, the wizard automatically creates a method in this controller that calls the function modules and ensures parameter transfer. See also Create Service Call.
