Select-Option display only

Hi Folks,

I want to display all the values for a select-option in the selection screen (value are coming from a database table) but restrict user from entering the values.

For that i have made a MODIF ID and have hidden it using the code below:

AT SELECTION-SCREEN OUTPUT.

LOOP AT SCREEN.

IF screen-group1 = 'HID'.

screen-input = 0.

ENDIF.

MODIFY SCREEN.

ENDLOOP.

Problem:

But the problem now is the select Option i am not able to see all value as the button "" is inactive.

The code is

But i am not able to view values expect "2".

Please let me know how to view all values of S_bukrs.

Thanks a lot in Advance!!
