Here is the example code

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.

Hi,

In your report declare

TYPE-POOL : VRM.

DATA: ws_name TYPE vrm_id,

ws_list TYPE vrm_values,

ws_value LIKE LINE OF ws_list,

ws_name2 TYPE vrm_id.

Under PBO event.

ws_value-key = '1'.

ws_value-text = 'YES'.

APPEND ws_value TO ws_list.

ws_value-key = '2'.

ws_value-text = 'NO'.

APPEND ws_value TO ws_list.

ws_name = your list box field name .

CALL FUNCTION 'VRM_SET_VALUES'

EXPORTING

id = ws_name

values = ws_list

EXCEPTIONS

id_illegal_name = 1

OTHERS = 2.

Don't forget to reward if useful....

good

this is the flow logiv under POV.*

process on value-request.

field wa_scr1-auart module create_dropdown_box1.

this is the code under the above mentioned module *

module create_dropdown_box1 input.

select distinct auart into corresponding fields of table it_auart from TVAK.

sort it_auart by auart.

call function 'F4IF_INT_TABLE_VALUE_REQUEST'

exporting

retfield = 'AUART'

value_org = 'S'

tables

value_tab = it_auart

exceptions

parameter_error = 1

no_values_found = 2

others = 3.

IF sy-subrc 0.

...

ENDIF.

endmodule. " CREATE_DROPDOWN_BOX1

declaration of the it_auart. *

types: begin of t_auart,

auart type auart,

end of t_auart.

data: it_auart type standard table of t_auart.

What actually this code is doing is that we are declaring a module "create_dropdown_box1" under POV.

Whenever we do that ,the POV is triggered at PBO and the module is executed.

On the execution of the module,the function 'F4IF_INT_TABLE_VALUE_REQUEST' populates the drop-down with the values in the internal table it_auart here.

thanks

PROCESS ON VALUE-REQUEST.

FIELD ifmtp-form_type MODULE fm_drop.

MODULE fm_drop INPUT.

CLEAR ifmtp.

REFRESH ifmtp.

ifmtp-form_type = 'C'.

APPEND ifmtp.

ifmtp-form_type = 'F'.

APPEND ifmtp.

ifmtp-form_type = 'H'.

APPEND ifmtp.

CALL FUNCTION 'F4IF_INT_TABLE_VALUE_REQUEST'

EXPORTING

retfield = 'FORM_TYPE'

value_org = 'S'

TABLES

value_tab = ifmtp.

IF sy-subrc <> 0.

MESSAGE ID SY-MSGID TYPE SY-MSGTY NUMBER SY-MSGNO
WITH SY-MSGV1 SY-MSGV2 SY-MSGV3 SY-MSGV4.

ENDIF.

ENDMODULE. " fm_drop INPUT

here ifmtp-form_type is my field which i have declared as listbox....

this is my dexlaration in TOP Module

DATA : BEGIN OF ifmtp OCCURS 0,

form_type LIKE zform_track_mast-form_type,

END OF ifmtp.

reward if usefull......
