Hi,

Use this type of logic. Though this code is for selection-screen, but you can use this type of logic for screens by using screen table and implement this logic in PAI.

REPORT z_sdn.
 
PARAMETERS:
  p_num RADIOBUTTON GROUP rad1 DEFAULT 'X' USER-COMMAND abc,
  p_char RADIOBUTTON GROUP rad1.
 
PARAMETERS:
  p_num1 TYPE i MODIF ID num,
  p_num2 TYPE i MODIF ID num,
  p_char1 TYPE c MODIF ID chr,
  p_char2 TYPE c MODIF ID chr.
 
 
AT SELECTION-SCREEN OUTPUT.
  IF p_num EQ 'X'.
    LOOP AT SCREEN.
      IF screen-group1 EQ 'CHR'.
        screen-active = 0.
        MODIFY SCREEN.
      ENDIF.
    ENDLOOP.
  ELSE.
    LOOP AT SCREEN.
      IF screen-group1 EQ 'NUM'.
        screen-active = 0.
        MODIFY SCREEN.
      ENDIF.
    ENDLOOP.
  ENDIF.

Thanks,

My requirement is to update a customized field of a selection screen.

I found there are two ways

1. Including the field so_where,so_flds,so_expr,

2. SUBMIT.......WITH FREE SELECTIONS AND USE THE FUNCTION MODULE 'FREE_SELECTIONS_RANGE_2_EX'

BUT I DON'T HAVE ANY IDEA HOW TO USE THAT.

CAN ANY ONE HELP ME PROVIDING SAMPLE CODE ON THAT.
