Hi Friends:

I got a scenario.I've 2 radio buttons on selection screen. When I click on first, it should make one filed as mandatory. When I click on second, it should make the prior field non-mandatory & make other field mandatory.I tried doing that. When I made first field mandatory & tried to click on the second radio button, it gave the error"fill in all the required fields". Plz help.

Hi,

U cannot do like that...u can default it as obligatory..

do like this..

parameters : p_case RADIOBUTTON GROUP grp USER-COMMAND app DEFAULT 'X',

p_test like mara-matnr.

parameters : p_case1 RADIOBUTTON GROUP grp

p_test1 like mara-werks.

IF p_case IS NOT INITIAL .

LOOP AT SCREEN.

CASE screen-name.

WHEN 'P_TEST' .

screen-input = 1.

MODIFY SCREEN.

WHEN 'P_TEST1'

screen-input = 0.

MODIFY SCREEN.

ENDCASE.

ENDLOOP.

ELSE.

LOOP AT SCREEN.

CASE screen-name.

WHEN 'P_TEST' .

screen-input = 0.

MODIFY SCREEN.

WHEN 'P_TEST1'

screen-input = 1.

MODIFY SCREEN.

ENDCASE.

ENDLOOP.

START-OF-SELECTION.

IF P_cASE IS NOT INITIAL.

IF P_TEST IS INITIAL..

THROW ERROR MESSAGE.

ENDIF.

ELSEIF P_CASE1 IS NOT INITIAL.

IF P_TEST1 IS INITIAL..

Hey hi!

Mandatory as in you want the fields under the selected radio button to be displayed and rest all should be disabled.. then if so.. this is the code..

firstly select all the fields under a radio button into a single group, and give a function code to the radio button and then write the loop at screen statement..

LOOP AT SCREEN.

IF SCREEN-GROUP1 = 'V1'. (The field is taken under a grp V1)

IF ZTAB2-VASTHU = 'X'. (The radio button name ZTAB2-VASTHU)

SCREEN-OUTPUT = 0.

SCREEN-INPUT = 1.

ELSE.

SCREEN-OUTPUT = 1.

SCREEN-INPUT = 0.

ENDIF.

MODIFY SCREEN.

ENDLOOP.

I used this in my requirement.. hope this will be helpful..

Regards,

Abhishek.

Hi Gaurav,

Write your code like this..

********************************

TABLES:

sscrfields.

PARAMETERS:

p_chk1 TYPE c RADIOBUTTON GROUP gr1 DEFAULT 'X',

p_mat TYPE matnr,

p_chk2 TYPE c RADIOBUTTON GROUP gr1,

p_wrk TYPE werks_d.

AT SELECTION-SCREEN.

IF sscrfields-ucomm EQ 'ONLI'.

IF p_chk1 EQ 'X' AND p_mat IS INITIAL.

MESSAGE 'Enter p_mat' TYPE 'E'.

ELSEIF p_chk2 EQ 'X' AND p_wrk IS INITIAL.

MESSAGE 'Enter p_wrk' TYPE 'E'.

ENDIF.

Abhishek..

The code which you have given, will not be able to make the field Mandatory.

It will only help us to either disable or enable giving input to the field, it will not make the input mandatory.

Hi,

You can use screen-required = 1. in the loop

to make a field mandatory.

TABLES sscrfields.

find the sample code.

<Code>

SELECTION-SCREEN BEGIN OF BLOCK b1 WITH FRAME NO INTERVALS.

PARAMETERS: a(10) TYPE c MODIF ID sc3 ,

b(10) TYPE c MODIF ID sc2 .

SELECTION-SCREEN END OF BLOCK b1.

SELECTION-SCREEN SKIP.

PARAMETERS: rad1 RADIOBUTTON GROUP rad1 USER-COMMAND ucomm,

rad2 RADIOBUTTON GROUP rad1.

AT SELECTION-SCREEN OUTPUT.

IF rad2 = 'X'.

LOOP AT SCREEN.

IF screen-group1 = 'SC3'.

screen-intensified = 1.

screen-active = 1.

screen-display_3d = 1.

screen-required = 1.

MODIFY SCREEN.

ENDIF.

IF screen-group1 = 'SC2'.

screen-intensified = 0.

screen-active = 1.

MODIFY SCREEN.

ENDIF.

ENDLOOP.

ENDIF.

IF rad1 = 'X'.

LOOP AT SCREEN.

IF screen-group1 = 'SC3'.

screen-intensified = 0.

screen-active = 1.

screen-display_3d = 1.

screen-required = 0.

MODIFY SCREEN.

ENDIF.

IF screen-group1 = 'SC2'.

screen-intensified = 1.

screen-active = 1.

screen-required = 1.

MODIFY SCREEN.

ENDIF.

ENDLOOP.

ENDIF.
