Video Lesson 9.6: Screen

In this lesson you will learn how to design and program simple screens with
input/output fields and pushbuttons.

Features of Screens

A screen not only consists of its layout with input/output fields, pushbuttons and other screen elements, but also a processing logic.

 (source code excerpts that are processed as the pre-/postprocessing of the screen display).

The layout can be designed very flexibly, with:

• input fields,
• output fields,
• radio buttons,
• check fields and,
• most importantly, pushbuttons with which the corresponding functions of the program can be executed.

Screen Sequence

• You start a screen sequence by calling up the first screen from the processing block of your program.
• After a screen is processed, the statically or dynamically defined screen sequence is processed.
• You call a screen in your program using the ABAP statement “CALL SCREEN <screen number>”
