Selection Screen

[Former Member]

I have a Check box P_CAT8. If this check box is checked, then 2 fields LIFNR and BELNR will me enabled and they are mandatory. But, without giving values in these 2 fields, if I again uncheck the check box, these fields should become disabled again. can anybody tell me how to handle this?

Hi Priyanka ,

You will have to use the event at selection screen output and inside this

loop at screen .

• YOUR CODE TO ENABLE/DISABLE A FEILD

endloop.

Hello,

Check this code:

[code]PARAMETERS: SP_CHECK AS CHECKBOX USER-COMMAND CHECK.
SELECT-OPTIONS: SO_MATNR FOR MARA-MATNR MODIF ID GRP.

AT SELECTION-SCREEN OUTPUT.
  IF SP_CHECK IS INITIAL.
    LOOP AT SCREEN.
      IF SCREEN-GROUP1 = 'GRP'.
        SCREEN-INPUT = '0'.
        SCREEN-OUTPUT = '1'.
        MODIFY SCREEN.
      ENDIF.
    ENDLOOP.
    CLEAR: SO_MATNR.
    REFRESH: SO_MATNR.
  ENDIF.

AT SELECTION-SCREEN ON SP_CHECK.
  PERFORM MATERIAL_CHECK.

FORM MATERIAL_CHECK.

  IF NOT SP_CHECK IS INITIAL.
    IF SO_MATNR[] IS INITIAL.
      LOOP AT SCREEN.
        IF SCREEN-NAME = 'SO_MATNR-LOW'.
          SCREEN-INPUT = '1'.
          SCREEN-OUTPUT = '0'.
          SCREEN-REQUIRED = '1'.
          MODIFY SCREEN.
        ENDIF.
      ENDLOOP.
    ENDIF.
  ENDIF.
ENDFORM.                    " MATERIAL_CHECK

Hi Priyanka,

You need to use the LOOP AT SCREEN logic over here, in the AT SELECTION SCREEN Event,

IF  P_CAT8 = 'X'.
 LOOP AT SCREEN.

 ENDLOOP.
Endif.

in my opinion this scenario is not possible .

cause i have checked the box so now the code has to show that these are the mandatory fields so without entering any fields if i try to process the screen then an error is triggerd saying to fill the screen ,

we cannot bypass once the system throws this error message .

we cannot make them disable .

parameters : p_cat8 as checkbox user-command r  modif id abc.


PARAMETERS: p_lifnr like lfa1-lifnr modif id def.

PARAMETERS: p_belnr like mseg-belnr modif id def.

at selection-screen output.

if p_cat8 ne ' '.
loop at screen.
if screen-group1 = 'DEF'.
screen-input = '1'.
screen-required = '1'.
modify screen.
endif.
endloop.

else.

loop at screen.
if screen-group1 = 'DEF'.
screen-required = '0'.
screen-input = '0'.
modify screen.
endif.
endloop.

endif.
