Selection-Screen field enable/disable

Former Member — Wed, 14 May 2008 12:31:29 GMT

Hi,

I have developed a report with a selection-screen.

In the selection-screen there are five fields.

The last field should remain disabled (display only) and if the value of the 4th field is 'P',should the last field become editable.

Please advise, how to do it.

I have tried the following code:

LOOP AT SCREEN.

IF screen-group1 = 'SC2'.

screen-input = '0'.

MODIFY SCREEN.

ENDIF.

ENDLOOP.

but this code doesnt work for the event "At selection-screen".

It works for "At selection-screen output".

Thanks in advance.

Regards,

Tejas

Hi Tejas,

First define your selection-screen. In the AT SELECTION-SCREEN OUTPUT event, check for the value of the third field and if is satisfies your condition, perform the below code, which you have given.

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

LOOP AT SCREEN.

IF screen-group1 = 'SC2'.

screen-input = '0'.

MODIFY SCREEN.

ENDIF.

ENDLOOP.

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

Hope this is helpful to you. If you need further information, revert back.

Reward all the helpful answers.

Hi,

It will work in at selection-screen output. But you need to press ENTER.

Check the below code.

parameters: p_char type c,

p_num type i.

at selection-screen output.

loop at screen.

if screen-name = 'P_NUM'.

if p_char = 'P'.

screen-input = 1.

else.

screen-input = 0.

endif.

modify screen.

endloop.
