Setting screen field attributes

[Former Member]

Hello ,

I am working on a code where I am required to set the field attribute to

Output Only OR  Input possible depending upon certain conditions.

Does anyone know how to go about to get this functionality ?

I have a vivid idea that we will have to access the attributes in the PBO module of the screen but how ?

Hi,

You need to use the loop at screen command in the PBO.

Have a look here :

Hi Shubhendu,

We can set the field I/O dynamically. If you are working specifically with module pool programming, could you please give a brief desciption of the issue being faced.

You can try the below code and check output for your reference

" when you check a single check box - the other two will get disabled.

tables screen.

parameters: w1 as checkbox modif id 1 user-command flag,
             w2 as checkbox modif id 2 user-command flag1,
             w3 as checkbox modif id 3 user-command flag2.

at selection-screen output.

IF w1 = 'X' .
loop at screen.
   if screen-group1 = '2' or screen-group1 = '3'.
     screen-input = '0'.
endif.
modify screen.
endloop.



elseif w2 = 'X'.

   loop at screen.
   if screen-group1 = '1' or screen-group1 = '3'.
     screen-input = '0'.
endif.
modify screen.
endloop.


elseif w3 = 'X'.

loop at screen.
   if screen-group1 = '1' or screen-group1 = '2'.
     screen-input = '0'.
endif.
modify screen.
endloop.

ENDIF.
