hi,

You can Assign the default value in the INITIALIZATION event.

And You can Apply validations on the field in

AT SE:ECTION-SCREEN OUTPUT.

This Event is triggered after the initialization but before the display of the Screen.

Hope this will help.

Try this code:

report z_demo.

TYPE-POOLS: vrm.

DATA: name TYPE vrm_id, list TYPE vrm_values, value LIKE LINE OF list.

TABLES: sscrfields.

PARAMETERS: ps_parm AS LISTBOX VISIBLE LENGTH 10

USER-COMMAND abc.

PARAMETERS: p_bwart like T156-BWART.

INITIALIZATION.

name = 'PS_PARM'.

value-key = '1'. value-text = 'Tradable to Spare'.

APPEND value TO list.

value-key = '2'. value-text = 'Spare to Tradable'.

APPEND value TO list.

AT SELECTION-SCREEN OUTPUT.

CALL FUNCTION 'VRM_SET_VALUES'

EXPORTING

id = name

values = list.

if ps_parm = 1.

p_bwart = '099'.

else.

clear p_bwart.

endif.

LOOP AT SCREEN.

IF ps_parm = 1.

IF screen-name = 'P_BWART' .

screen-INPUT = 0.

ENDIF.

MODIFY SCREEN.

elseIF ps_parm = 2.

IF screen-name = 'P_BWART' .

screen-INPUT = 1.

ENDIF.

MODIFY SCREEN.

endif.

ENDLOOP.

AT SELECTION-SCREEN.

IF sscrfields-ucomm = 'ABC'.

ENDIF.

START-OF-SELECTION.

WRITE: / 'Parameter:', ps_parm.

Similarly u can do this for Material Description makt-maKTX also.
