Need a drop down for a selection screen

Former Member — Thu, 18 Jan 2007 09:30:53 GMT

HI all,

I need a drop down for a selection screen.

say for eg: Field is MARA-MTART (Material Type). The selection is optional and the dropdown should be using check table: T134

How to get a dropdown? I think a function module is used , but I dont remember the name.

Kindly reply.

Thanks in advance.

Hi ,

The FM is VRM_SET_VALUES.

here is a sample program which does the same


type-pools : VRM.
tables : T134.
Data : it_1 type VRM_VALUES ,
       v_index type i ,
       wa like line of it_1.

parameter : s_MTART LIKE T134-MTART AS LISTBOX  VISIBLE
               LENGTH 6  OBLIGATORY.
INITIALIZATION.
clear v_index.


select MTART INTO T134-MTART from T134.
wa-KEY = T134-MTART.
append wa to it_1.
ENdselect.


CALL FUNCTION 'VRM_SET_VALUES'
  EXPORTING
    ID                    = 'S_MTART'
    VALUES                = it_1
* 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.

Please optamize the select statement and a better option would be selecting data from T134T , as you get the description also , populate the description in TEXT field if the table it_1

Arun

Use FM 'VRM_SET_VALUES'

Ex:

TYPE-POOLS: vrm.

data:

ws_cnt type i,

ws_list_values type vrm_values,

ws_list_line like line of ws_list_values.

data: begin of ws_tab,

<field> like <table-field>,

end of ws_tsact.

data: i_tab like ws_tab occurs 0 with header line.

data: ws_text like <table-field>.

selection-screen: begin of line.

selection-screen: comment (31) <text> for field par_comm.

PARAMETERS: <field_name> AS LISTBOX VISIBLE LENGTH 20.

selection-screen: end of line.

append 'create' 'change' 'delete' to i_tab.

LOOP AT i_tab INTO ws_tab.

ws_cnt = ws_cnt + 1.

ws_list_line-key = ws_cnt.

ws_list_line-text = ws_tab-field.

APPEND ws_list_line TO ws_list_values.

ENDLOOP.

CALL FUNCTION 'VRM_SET_VALUES'

EXPORTING

id = 'PAR_COMM'

values = ws_list_values.

ENDIF.

Hi jayasree,

check this,

TABLES : mara,

t134.

TYPE-POOLS: vrm.

DATA: name TYPE vrm_id,

w_mtart LIKE mara-mtart,

list TYPE vrm_values,

value LIKE LINE OF list.

PARAMETERS: p_mtart LIKE mara-mtart AS LISTBOX VISIBLE LENGTH 10.

AT SELECTION-SCREEN OUTPUT.

name = 'P_MTART'.

SELECT mtart

UP TO 10 ROWS

FROM t134

INTO w_mtart.

value-key = W_MTART.

value-text = W_MTART.

APPEND value TO list.

CLEAR W_MTART.

ENDSELECT.

CALL FUNCTION 'VRM_SET_VALUES'

EXPORTING

id = name

values = list.

START-OF-SELECTION.

WRITE: / 'PARAMETER:', p_mtart.
