This section describes the dialogs that you can use in ABAP to communicate with program users. It explains how to pass data between user dialogs and ABAP programs, how to define user dialogs within your programs, and how to process user input.

Currently, ABAP programs with type 1 (executable programs), M (module pools), and F (function groups) can contain their own user dialogs. In the future, it is planned to allow classes in ABAP Objects also to have screens.
