Summary

A subscreen is a screen that is displayed in a specified area of another screen(the “main” screen). A subscreen cannot be displayed by itself.

To include a subscreen in a predefined area on the “main” screen, use the “CALL

SUBSCREEN” statement in the “main” screen‟s PBO event.

If the subscreen contains any PAI code, use the “CALL SUBSCREEN” statement

in the PAI event of the “main” screen. A subscreen is created just like any other screen of an online program. The only

difference is the screen type specified in the Screen Attributes section of the

Screen Painter. The screen type for a subscreen is appropriately called

“Subscreen”.

The following ABAP/4 statements cannot be used in a subscreen‟s PBO or PAImodules (instead, they must be used in the “main” screen): SET PF-STATUS,

SET TITLEBAR, SET SCREEN, LEAVE TO SCREEN,CALL SCREEN.
