PBO of the Selection Screen

In the PBO of the selection screen, the

AT SELECTION-SCREEN OUTPUT

event is triggered. This event block allows you to modify the selection screen directly before it is displayed.

Example

PARAMETERS: TEST1(10) MODIF ID SC1,
            TEST2(10) MODIF ID SC2,
            TEST3(10) MODIF ID SC1,
            TEST4(10) MODIF ID SC2.
AT SELECTION-SCREEN OUTPUT.
LOOP AT SCREEN.
  IF SCREEN-GROUP1 = 'SC1'.
    SCREEN-INTENSIFIED = '1'.
    MODIFY SCREEN.
    CONTINUE.
  ENDIF.
  IF SCREEN-GROUP1 = 'SC2'.
    SCREEN-INTENSIFIED = '0'.
    MODIFY SCREEN.
  ENDIF.
ENDLOOP.

The parameters TEST1 and TEST3 are assigned to the modification group SC1, while TEST2 and TEST4 are assigned to group SC2. During the AT SELECTION-SCREEN OUTPUT event, the INTENSIFIED field of internal table SCREEN is set to 1 or 0, depending on the contents of the GROUP1 field.
