set the function code to list box. once you select the list box field, the function code will be triggered, after that PBO will trigger ,based on the value you can disable the screen field in PBO using loop at screen.

loop at screen.
if list_field = '1233'.
 if screen-name = 'SCREENFIELD'.
 screen-input  = 0.
 modify screen.
endif.
endif.

endloop.

Hi Pranu,

As Vijay has specified the sample code for you to disable the field in the module pool


loop at screen.
if list_field = '1233'.
 if screen-name = 'SCREENFIELD'.
 screen-input  = 0.
 modify screen.
endif.
endif.
 
endloop.

Inside the Loop just k set a Flag = 1 and then after if again check the Flag to disable the other field.


data: flag type i.  " decalare it in the Top include

loop at screen.
if list_field = '1233'.
 if screen-name = 'SCREENFIELD'.
 flag = 1
 screen-input  = 0.
 modify screen.
endif.
if flag = 1.
  if screen-name = 'XXXX' OR
   screen-name = 'YYY'.

     screen-input  = 0.   "----" This will disable your radio button where XXX and YYY is your radio buttons
      modify screen.


  endif.
endif.
endif.
 
endloop.

Thanks,

Chidanand

using the screen group you can disable/enable the elements with minimal coding.

i hope you know about screen groups, click on any field in the attributes popup you can see group1,2,3,4

loop at screen.
if list_field = '1233'.
 if screen-group1 = 'GRP1'.  "<--assign the screen group to all the elements which you want 
 screen-input  = 0.
 modify screen.
endif.
endif.
 
endloop.

Hi,

This is Ur Code.

loop at screen.

IF ZATC_TOUR1-ACCOMODATION = 'GUEST HOUSE'.

if screen-group1 = 'G1' and screen-group2 = 'G2'.

screen-input = 0.

modify screen.

endif.

endloop.

Change it as :

IF ZATC_TOUR1-ACCOMODATION = 'GUEST HOUSE'.

loop at screen.

if screen-group1 = 'G1' OR screen-group2 = 'G2'.

screen-input = 0.

modify screen.

endif.

endloop.

endif.

In the If Condition change AND as OR.
