Hi,

For validating a selection screen field, u should consider the header table that is a must.

Eg: My selection screen field is marc-matnr.

U have to see whether the matnr in marc is having any check table if so u have to refer the check table not marc.

So to validate this fiedl.

SELECT-OPTIONS: s_matnr LIEK mara-matnr.

AT SELECTION SCREEN ON s_matnr.

IF NOT s_matnr[] IS INITIAL.

select matnr from mara

into mara-matnr

where matnr = s_matnr.

IF sy-subrc NE 0.

MESSAGE i128.

LEAVE LIST-PROCESSING.

ENDIF.

Hope this solves ur query.

Thanks,

Shankar

Try using at selection-screen output .

loop at screen .

make the screen visible.

endloop.

Check the sap help that is best with examples also.

Check transaction DWDM for selection screen examples or ABApdocu.

Please reward if useful.

Hi,

Say if the Two radio buttons are R1 and R2:

You can write:

If r1 = 'X'.

loop at screen.

if <Field name> = f1 or F2 ...

.........................

......................

modify screen.

endloop.

Put your cursor on LOOP press F1, it will take you to correct SAP documentation.

You can Modify the fields which you wants to hide based on the selected Radio button.

endif.

Hi Sanjana,

U can use the AT SELECTION-SCREEN event to do the necessary validation and checks..so in your case if a particular is mandatory for rd1 and not for rd2..in that case please take out the obligatory clause from the parameter and do the validation in the above event..basically if rd1 is selected and the particular parameter is blank ..display an error message.

check this sample code.

REPORT ztest.

TABLES: mara,vbak.

PARAMETERS: r_m RADIOBUTTON GROUP g1 DEFAULT 'X' USER-COMMAND ABC,

r_s RADIOBUTTON GROUP g1.

parameters: p_matnr like mara-matnr,

p_vbeln like vbak-vbeln.

AT SELECTION-SCREEN OUTPUT.

IF r_m = 'X'.

LOOP AT SCREEN.

IF screen-name = 'P_VBELN'.

screen-input = 0.

MODIFY SCREEN.

ENDIF.

ENDLOOP.

ELSE.

LOOP AT SCREEN.

IF screen-name = 'P_MATNR'.

screen-input = 0.

MODIFY SCREEN.

ENDIF.

ENDLOOP.

ENDIF.

AT SELECTION-SCREEN.

<b> IF sy-ucomm = 'ONLI'.</b>

IF r_m = 'X'.

IF P_matnr IS INITIAL.

MESSAGE e000(zz) WITH 'error'.

ENDIF.

Regards,

Priyanka.<b></b>
