Thanks, works fine for report with a selection screen, but i have a dynpro and therefore no parameter clause.

Declare a variable with the same name as the dropdown box in TOP INCLUDE. And then, in the PBO module set the default value you want to this variable. Hope this helps.

hi,

TYPE-POOLS: vrm.

DATA: name TYPE vrm_id,

list TYPE vrm_values,

value LIKE LINE OF list.

PARAMETERS: ps_parm(10) AS LISTBOX VISIBLE LENGTH 10.

AT SELECTION-SCREEN OUTPUT.

name = 'PS_PARM'.

value-text = 'Line 1'.

APPEND value TO list.

Hi Rainer ,

In the PBO afte the FM has been called assign the default value to the screen parameter.

I feel this should work.

Hi ..

For Eg:

The Listbox field in the Screen Painter is MARA-MTART.

Then to Populate a Default value.

1) Declare the Global variable in the Program. Top include:

TABLES MARA.

2) In the PBO module called from the Screen put a Default value in this variable.

MARA-MTART = 'ROH'.

This value appears as default value in Checkbox.

Or in the Screen Painter :

Open the attributes of the Listbox

Enter the Default value in the TEXT attribute..

reward if Helpful.

Hi thanks, works fine. Is there any chance of getting rid of the empty line in the selection values? It seems t be there by default but rather to have an empty line would prefer something like "0 None".

U've to make the parameter as <b>OBLIGATORY</b> to get rid of the empty line.
