FM VRM_SET_VALUE To List Box

In my report I created alternative Bill of material (Stlal) from table mast as listbox and that list box must contain 01 to 06 no.s. How to do that? I am using F.M VRM_SET_VALUE.

This example may help you:

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-KEY = '1'.
VALUE-TEXT = 'LINE 1'.
APPEND VALUE TO LIST.
VALUE-KEY = '2'.
VALUE-TEXT = 'LINE 2'.
APPEND VALUE TO LIST.
CALL FUNCTION 'VRM_SET_VALUES'
EXPORTING
ID = NAME
VALUES = LIST.
START-OF-SELECTION.
WRITE: / 'PARAMETER:', PS_PARM.
