Default Value From Dropdown list

Former Member — Thu, 25 Dec 2008 09:44:29 GMT

i have a field in screen 1000..where i'm using vrm_set_values to get dropdown list for the field..for removing the balnk value i made it mandatory..but i'm not able to get default value in the screen field..even though i'm assigning it a value..how to do it?

SELECT * FROM ZESCHEME INTO TABLE IT_ZSCHEME.

IF IT_ZSCHEME IS INITIAL.

LOOP AT IT_ZSCHEME.

SVID = 'ZEPRE_M-SCHEME'.

SVALUE-KEY = IT_ZSCHEME-SCHEME.

APPEND SVALUE TO SVALUES.

ENDLOOP.

ENDIF.

CALL FUNCTION 'VRM_SET_VALUES'

EXPORTING

ID = SVID

VALUES = SVALUES

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.

IF ZEPRE_M-SCHEME IS INITIAL.

ZEPRE_M-SCHEME = 'FREE'.

ENDIF.

is this the right approch to do?

i hope ur Internal table SVALUES needs to be structured n populated properly..

chek out this code:

THE TOP INCLUDE:

TYPES: begin of stru_t161t,

BSTYP type t161t-BSTYP,

BSART type t161t-BSART,

BATXT type BATXT,

end of stru_t161t.

types : BEGIN OF STRU_TEXT, "STRUCTURE FOR FUNCTION MODULE

KEY(40) TYPE C, " FOR DROPDOWN BOX

TEXT(80) TYPE C,

END OF STRU_TEXT.

data : it_t161t type TABLE OF stru_t161t,

wa_t161t type stru_t161t,

it_text type TABLE OF STRU_TEXT,

wa_text type STRU_TEXT.

IN THE PBO:

MODULE STATUS_1000 OUTPUT.

SELECT

BSTYP

BSART

BATXT

into table it_t161t

from t161t

where bstyp = 'B'

and SPRAS = 'E'.

clear wa_text.

refresh it_text.

loop at it_t161t into wa_t161t.

move wa_t161t-bsart to wa_text-key.

move wa_t161t-batxt to wa_text-text.

append wa_text to it_text.

endloop.

CALL FUNCTION 'VRM_SET_VALUES'

EXPORTING

ID = 'V_DRPDWN' "'V_DRPDWN' is the screen name of the dropdown field

VALUES = it_text

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.

ENDMODULE. " STATUS_1000 OUTPUT

In the vrm_set_values, to put something as default values, you must use the id = ' ' for that particular value.

Check out the following code. I think this will help you.

PARAMETERS: p_day TYPE char4 AS LISTBOX VISIBLE LENGTH 6 OBLIGATORY.

TYPE-POOLS: vrm.

DATA: l_sid TYPE vrm_id,

l_i_val TYPE vrm_values,

l_val LIKE LINE OF l_i_val.

INITIALIZATION.

l_sid = 'p_day'.

l_val-key = '0'.

l_val-text = 'SUN'.

APPEND l_val TO l_i_val.

l_val-key = '1'.

l_val-text = 'MON'.

APPEND l_val TO l_i_val.

l_val-key = '2'.

l_val-text = 'TUE'.

APPEND l_val TO l_i_val.

CALL FUNCTION 'VRM_SET_VALUES'

EXPORTING

id = l_sid

values = l_i_val

EXCEPTIONS

id_illegal_name = 1

OTHERS = 2.

IF sy-subrc = 0.

ENDIF.
