Hello,

I ahve requirement where the fields on selection screen should be displayed dynamically ? For example there are three fields on screen. Now those fields should be dispalyed on screen only if program matches certain logic.

I know that buttons in application toolbar can be displayed dynamically but not sure about screen fields ?

Please help.

Hi,

You will have to use AT SELECTION-SCREEN OUTPUT EVENT and in this event you will have to use LOOP AT SCREEN.

Hi,

Put your logic in the AT selection-screen output.

Use the ACTIVE field of the structure SCREEN to hide (active = space) or display ( active = 1) the fields on the selection screen.

hi,

make visible the screen field which will come default and other field should be invisible

AT SELECTION-SCREEN. IF you want to change the screen display, modify the internal table SCREEN of that screen field.

in selection screen

AT selection screen.

if <some condition>

loop at screen.

if <screen field> = field name.

invisible = 'x'.

endif,

modofy screen.

endloop.

screen internal table contains all information regarding screen.

please check and let me know if have found any problrm
