in PBO, use the FM VRM_SET_VALUES for getting the drop down.

CALL FUNCTION 'VRM_SET_VALUES'

EXPORTING

id = V_id -> field fro which u want drop down

values = it_values[] -> values that u need to display in the dropdown

EXCEPTIONS

id_illegal_name = 1

OTHERS = 2.

IF sy-subrc <> 0.

MESSAGE ID SY-MSGID TYPE SY-MSGTY NUMBER SY-MSGNO

WITH SY-MSGV1 SY-MSGV2 SY-MSGV3 SY-MSGV4.

ENDIF.

also in the layout set the property of the field to drop down with key.

Hi,

In the Layout go to Attributes of the field and in Drop Down select List Box and in the PBO use FM 'VRM_SET_VALUES' to populate your list box.

Cheers

try below example in PBO


name = 'PS_PARM'.  " List Control Name
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.

Hi,

Check the below code.

TYPE-POOLS: VRM.

DATA:V_NUM TYPE I.

DATA:NAME TYPE VRM_ID,

LIST TYPE VRM_VALUES,

VALUE LIKE LINE OF LIST.

DATA:I_WORKPATTERN LIKE ZWORKPAT OCCURS 0 WITH HEADER LINE.

DATA:ZPATTXT(60).

MODULE WORKPATTERN_LISTBOX OUTPUT.

NAME = 'P9434-ZWORKPATTERN'. --> Screen Field

IF V_NUM IS INITIAL.

CLEAR I_WORKPATTERN.

REFRESH I_WORKPATTERN.

SELECT *

FROM ZWORKPAT --> List box contents from the z table

INTO TABLE I_WORKPATTERN.

IF NOT I_WORKPATTERN[] IS INITIAL.

LOOP AT I_WORKPATTERN.

VALUE-KEY = I_WORKPATTERN-ZWORKPATTERN.

VALUE-TEXT = I_WORKPATTERN-ZWORKPATTERN.

APPEND VALUE TO LIST.

ENDLOOP.

ENDIF.

CALL FUNCTION 'VRM_SET_VALUES'

EXPORTING

ID = NAME

VALUES = LIST

EXCEPTIONS

ID_ILLEGAL_NAME = 1

OTHERS = 2.

IF SY-SUBRC 0.

CLEAR SY-SUBRC.

ENDIF.

V_NUM = V_NUM + 1.

ENDIF.

jus try to debug and check where the values are being populated from. if it being populated from an internal table u can the two values here. U need to check in the PBOof the screen.
