use the fn module "VRM_SET_VALUES".

example:

DATA: NAME TYPE VRM_ID,

LIST TYPE VRM_VALUES,

VALUE LIKE LINE OF LIST.

REFRESH LIST.

NAME = 'ABC'.

MOVE: '1' TO VALUE-KEY,

'ABCD' TO VALUE-TEXT.

APPEND VALUE TO LIST.

MOVE: '2' TO VALUE-KEY,

'XYZS' TO VALUE-TEXT.

APPEND VALUE TO LIST.

CALL FUNCTION 'VRM_SET_VALUES'

EXPORTING

ID = NAME

VALUES = LIST.

Hi,

REPORT ZLIST.

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.

Also Chek this link for a sample code:

You can use function module VRM_SET_VALUES for this.

Check the sample program: DEMO_DYNPRO_DROPDOWN_LISTBOX,

in SE51 with screen: 0100. and

RSDEMO_DROPDOWN_LISTBOX

Hi,

Another example:


report ad_test.

type-pools: vrm.
data: it_val type vrm_values,
      w_line like line of it_val.
parameters p_bukrs like t001-bukrs as listbox
           visible length 25 obligatory.

initialization.
  select bukrs butxt from t001 into (w_line-key, w_line-text).
    append w_line to it_val.
    check p_bukrs is initial.
    p_bukrs = w_line-key.
  endselect.

at selection-screen output.
  call function 'VRM_SET_VALUES'
       exporting
            id     = 'P_BUKRS'
            values = it_val.

end-of-selection.
  write: / 'Company Code:', p_bukrs.

Hi Kokwei,

Take this simple example..

This is a simple eg. of Static List Box..

REPORT  ZSATLISTBOX.
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.
*populate the list with the value you want-------

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 the FM VRM_SET_VALUES-----------------------

CALL FUNCTION 'VRM_SET_VALUES'
 EXPORTING ID = NAME 
 VALUES = LIST.
*print The selected one---------------------------
START-OF-SELECTION.
WRITE: / 'PARAMETER:', PS_PARM.

Hi Kokwei,

1. I suppose u are doing in module pool.

2. we have to do things :

a) write some code in pai

b) write some code in a module

3. in pai

PROCESS AFTER INPUT.

PROCESS ON VALUE-REQUEST.

field mylistab module abc.

(where mylisttab = field screen - listbox name)

and abc = module (where we will write code)

4. code for module abc.

MODULE abc INPUT.

DATA : BEGIN OF itab OCCURS 0,

bukrs LIKE t001-bukrs,

butxt LIKE t001-butxt,

END OF itab.

SELECT * FROM t001 INTO CORRESPONDING FIELDS OF TABLE itab.

CALL FUNCTION 'F4IF_INT_TABLE_VALUE_REQUEST'

EXPORTING

retfield = 'BUKRS'

value_org = 'S'

dynprofield = 'MYLISTTAB'

dynpprog = sy-repid

dynpnr = sy-dynnr

TABLES

value_tab = itab

EXCEPTIONS

parameter_error = 1

no_values_found = 2

OTHERS = 3.

ENDMODULE. " abc INPUT

amit m.

Hi Kokwei,

Could u explain ur requirement more clearly....

A dropdown box offers the user a predefined set of input values from which to choose. It is not possible to type a entry into a dropdown box, instead, the user must use one of the values from the list.

Anjali

Hi,

There is one way i just found. But not sure if this is ur requirement.

GO to screen painter, create an Input/output field.

In the attributes:

NAME: MARA-MTART

Dropdown: Listbox.

call this screen in ur program>

Eg:

report test.

Call screen 100.

Here, you will get all the entries in MARA-MTART.

Let us know if this is ur requirement.

Also, tell us what is it that u want in your list box.

Regards,

Anjali

THERE IS A FM TO TRANSFER VALUES TO A LIST BOX.

VRM_SET_VALUES

Populates listbox parameter (like value 1 value 2 value 3 value 4 ) with values for selection

EXAMPLE

report z.

type-pools: vrm.

data: it_val type vrm_values,

w_line like line of it_val.

parameters p_bukrs like t001-bukrs as listbox

visible length 25 obligatory.

initialization.

select bukrs butxt from t001 into (w_line-key, w_line-text).

append w_line to it_val.

check p_bukrs is initial.

p_bukrs = w_line-key.

endselect.

at selection-screen output.

call function 'VRM_SET_VALUES'

exporting

id = 'P_BUKRS'

values = it_val.

end-of-selection.

write: / 'Company Code:', p_bukrs.

IF THIS FINDS USEFUL PLEASE REWARD POINTS.

REGARDS,

ANOOP.

Hello Kokwei,

Please first activate the screen with the listbox in the Layout Editor.

Then to populate the listbox, the input field with the listbox needs to be declared in your program with a datatype in DDIC (transaction SE11) with a domain that has a value list ("single vals" under the tab "Value Range").

Then when you activate and run the program, the listbox is automatically populated (at runtime) with the values from the value list.

I just tested this with a domain of type INT4, restricted to the values 1, 2, 3.

Kind regards,

Michael Kraemer
