Procedure documentationActivate ICF Service of Web Dynpro App

 

To call a Web Dynpro app, you use a dedicated URL, which accesses your back-end system.

A component called the Internet Communication Framework (ICF) runs on your back-end system. The URL calls a service in the ICF (ICF Service). The ICF service executes one or more ABAP programs to compile the requested data and returns it to the web browser.

Each Web Dynpro app uses its own ICF service.

For security reasons, all ICF services initially are inactive and have to be activated first.

Note Note

We recommend that you only activate the services for the apps you want to use.

End of the note.
