Enabling and disabling fields on selection screen

Former Member — Fri, 03 Apr 2009 11:24:30 GMT

Hi there experts...

I Have the following code, but i need to do add more conditions but I'm not able to do so.

PARAMETERS: ch_alv AS CHECKBOX DEFAULT 'X' USER-COMMAND cmd.
PARAMETERS: ch_tot AS CHECKBOX DEFAULT 'X' USER-COMMAND cmd MODIF ID cht.
PARAMETERS: rb1 RADIOBUTTON GROUP rb1 DEFAULT 'X' MODIF ID rbg.
PARAMETERS: rb2 RADIOBUTTON GROUP rb1 MODIF ID rbg.

AT SELECTION-SCREEN OUTPUT.

  LOOP AT SCREEN.
    IF CH_TOT = 'X'. 
      IF SCREEN-GROUP1  = 'RBG'.
        SCREEN-INPUT = 1. 
      ENDIF.
    ELSE. 
      IF SCREEN-GROUP1  = 'RBG'.
        SCREEN-INPUT = 0. 
      ENDIF.
    ENDIF.
    MODIFY SCREEN.
  ENDLOOP.

Now what I want is to only enable ch_tot, rb1 and rb2 parameters if ch_alv is checked, but I want to maintain the condition of enable RBG only if ch_tot is checked.

Can it be done?

Thanks

Check this.



PARAMETERS : ch_alv AS CHECKBOX USER-COMMAND abcd.
PARAMETERS: ch_tot AS CHECKBOX USER-COMMAND abcd MODIF ID abc.

parameters : p_param1(10) TYPE c modif id abc.
parameters : p_param2(10) TYPE c modif id abc.

AT SELECTION-SCREEN OUTPUT.
  LOOP AT SCREEN.
    IF ch_alv  = 'X'.
      IF screen-group1  = 'ABC'.
        screen-input = 1.
      ENDIF.
    ELSE.
      IF screen-group1  = 'ABC'.
        screen-input = 0.
      ENDIF.
    ENDIF.
    MODIFY SCREEN.
  ENDLOOP.

Hi,

after passing screen-input value, Use MODIFY SCREEN.

NOTE: Now what I want is to only enable ch_tot, rb1 and rb2 parameters if ch_alv is checked, but I want to maintain the condition of enable RBG only if ch_tot is checked.

Can it be done? How?
