Hi Shiek,

LIST BOX in SELECTION SCREEN

List Box is created in selection screen using PARAMETERS staement

with AS LISTBOX addition other attributes like VISIBLE LENGTH (width of listbox)

can be specified with the declaration.

PARAMETERS name(n) AS LISTBOX VISIBLE LENGTH n.

Here n is an integer and name is the name of parameter.

To populate the value list we use the FM VRM_SET_VALUES and the

selection screen event AT SELECTION-SCREEN OUTPUT is used to write the code to fill it.

VRM_SET_VALUES

The function module VRM_SET_VALUES is used to fill the value list associated with a List Box .This FM uses types which are declared in type group VRM. So

we should declare TYPE-POOLS VRM before using this FM.

Some important types declared in the VRM type group are

VRM_ID

It refers to the name of the input/output field associated with list box

VRM_VALUES

It refers to the internal table consisting of two fields TEXT(80C) and KEY(40)C

that will be used to create the list values.

CALL FUNCTION 'VRM_SET_VALUES'

EXPORTING

ID = name of screen element ,it is of TYPE VRM_ID

VALUES = internal table containing values,of TYPE VRM_VALUES

hi Sheik, try this code, it works.

Check the following code:

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.
