Hi,

You nee dto use following logic in PAI of the program.

check the value for first listbox.If its populated, then loop at screen.

and set the second list box screen field as active.

Eg:

if listbox1 = 'yes' or listbox1 = 'No'.

loop at screen.

If screen-name = 'listbox2'.

screen-active = '1'.

else

screen-activ = '0'.

endif.

modify screen.

endif.

basically you are enabling or disabling t he field.Screen is a structure that at runtime holds values for all screen fields properties.

HI Siva,

Once you assign a function code to a list box in Screen painter automatic Event(PAI thus PBO) is triggered

Check the below thread

populate drop down menu based on entry in another field
