Hi check the forum for loop at screen, there you can find the solution...

you will be using at selection screen event and loop at structure SCREEN.

Is there no way to to use group keyword in check boxes as used by radio buttons..

[former_member156446]

as far as I know there is not option for checkboxes like groups for radio buttons.

but you can give a same Modif ID for all the checkboxes.

No, there is no way to assign a Group to Checkboxes. However if you insist to use use checkbox instead of radiobuttons, you will have to program this in AT SELECTION-SCREEN event by assigning a user command to each check box so that it triggers a PAI and there you can check which check box was selected and uncehck the rest of the checkboxes.

PARAMETERS : chk_1 AS CHECKBOX USER-COMMAND usr1.
PARAMETERS : chk_2 AS CHECKBOX USER-COMMAND usr2.
PARAMETERS : chk_3 AS CHECKBOX USER-COMMAND usr3.
PARAMETERS : chk_4 AS CHECKBOX USER-COMMAND usr4.


AT SELECTION-SCREEN.

  CASE sy-ucomm.
    WHEN 'USR1'.
      CLEAR : chk_2, chk_3, chk_4.
    WHEN 'USR2'.
      CLEAR : chk_1, chk_3, chk_4.
    WHEN 'USR3'.
      CLEAR : chk_1, chk_2, chk_4.
    WHEN 'USR4'.
      CLEAR : chk_1, chk_2, chk_3.
  ENDCASE.

But I would still recommend you use radiobutton

does it mean, that only one checkbox can be selected at a time? than why don't you use radiobuttons (instead of checkboxes)? The funcionality you need will come automatically...

use AT SELECTION-SCREEN on output.

event

and by using

loop at screen .

modify screen.

endloop.

and by using screen structure you can achieve it.

Hi,

Advait is correct..use radiobuttons instead...have a look at the below sample code..

IF p_pserv IS INITIAL.

LOOP AT SCREEN.

CASE screen-name.

WHEN 'P_PFILE1'.

screen-input = 0.

MODIFY SCREEN.

WHEN 'P_PFILE2'.

screen-input = 0.

MODIFY SCREEN.

WHEN 'P_ERRFL1'.

screen-input = 0.

MODIFY SCREEN.

WHEN 'P_ERRFL2'.

screen-input = 0.

MODIFY SCREEN.

ENDCASE.

ENDLOOP.

ELSE.

LOOP AT SCREEN.

CASE screen-name.

WHEN 'P_AFILE1'.

screen-input = 0.

MODIFY SCREEN.

WHEN 'P_AFILE2'.

screen-input = 0.

MODIFY SCREEN.

WHEN 'P_AERFL1'.

screen-input = 0.

MODIFY SCREEN.

WHEN 'P_AERFL2'.

screen-input = 0.

MODIFY SCREEN.

ENDCASE.

ENDLOOP.

ENDIF.

Hello,

Its better to use radio buttons rather than going for the check boxes.
