How to multiply two collumn in collection.

Question

hi
i am using collection for creating a bill .Now i want to calculate Total Amount = Quantity * Rate .
Here APEX_ITEM.TEXT(9,a.c008) c008 is use for Quantity,
This is use for Rate APEX_ITEM.SELECT_LIST_FROM_QUERY(10,a.c009,'SELECT RATE D, RATE R FROM ITEM_DETAILS WHERE ITEM_NAME =''' || a.c006|| '''',) c009,
This is use for Total Amount Column APEX_ITEM.TEXT(11,a.c010) c010
This is my Collection code
select APEX_ITEM.HIDDEN(1,SEQ_ID),
APEX_ITEM.TEXT(2,a.c001) c001,
APEX_ITEM.TEXT(3,a.c002) c002,
APEX_ITEM.TEXT(4,a.c003) c003,
APEX_ITEM.TEXT(5,a.c004) c004,
APEX_ITEM.SELECT_LIST_FROM_QUERY(6,a.c005,'SELECT ITEM_GROUP D,ITEM_GROUP R FROM ITEM_GROUP_DETAILS order by ITEM_GROUP',
'style="width:110px" '
||'onchange="get_select_list_xml(this,''f7_'|| LPAD (seq_id, 4, '0')
||''')"',
'YES',
'0',
'-Select-',
'f6_'|| LPAD (seq_id, 4, '0'),
NULL,
'NO') c005,
APEX_ITEM.SELECT_LIST_FROM_QUERY(7,a.c006,'SELECT ITEM_NAME D,ITEM_NAME R FROM ITEM_DETAILS WHERE ITEM_GROUP =''' || a.c005|| '''' ,
'style="width:110px"'
||'onchange="get_select_list_xml21(this,''f10_'|| LPAD (seq_id, 4, '0')
||''')"',
'YES',
'0',
'-Select Name -',
'f7_' || LPAD (seq_id, 4, '0'),
NULL,
'NO') c006,
APEX_ITEM.TEXT(8,a.c007) c007,
APEX_ITEM.TEXT(9,a.c008) c008,
APEX_ITEM.SELECT_LIST_FROM_QUERY(10,a.c009,'SELECT RATE D, RATE R FROM ITEM_DETAILS WHERE ITEM_NAME =''' || a.c006|| '''',
'style="width:110px"',
'YES',
'0',
'-Select Rate -',
'f10_' || LPAD (seq_id, 4, '0'),
NULL,
'NO') c009,
APEX_ITEM.TEXT(11,a.c010) c010
FROM APEX_collections a
where a.collection_name = 'ABC'
For With out Refresh I am using
<script>
function amtItems(){
function getVal(item){
if($x(item).value != "")
return parseFloat($x(item).value);
else
return 0;
$x('c010').value = getVal('c008') * getVal('c009');
</script>
How Can i Multiply Quantity * Rate in to total Amount Column Without Refresh.
How can i use onBlur="javascript:amtItems()" in collection.
Thanks

Hi,
Call a PERFORM in ur form with 2 Using paramters (&RESBD-MENGE(C)&, &RESBD-GPREIS&) and use another changing parameter to get the value after multiplying above two. Define this PERFORM in driver program.
Eg:
In Script:
DEFINE : &tot_value&
PERFORM z_total_value IN PROGRAM z_cal_total USING &RESBD-MENGE& &RESBD-GPREIS&
                                    changing &tot_value&
In Program z_cal_total:
FORM z_total_value using in_tab structure itcsy
                           changing out_tab structure itcsy.
data : lv_menge TYPE resbd-menge,
          lv_gpreis TYPE resbd-gpreis,
          lv_total TYPE resbd-menge.
READ table in_tab with KEY name = 'RESBD-MENGE'.
IF sy-subrc EQ 0
  lv_menge = in_tab-value.
ENDIF.
READ table in_tab with KEY name = 'RESBD-GPREIS'.
IF sy-subrc EQ 0
  lv_gpreis = in_tab-value.
ENDIF.
READ table out_tab with KEY name = 'TOT_VLAUE'.
IF sy-subrc EQ 0.
  lv_total = lv_menge * lv_gperis.
   out_tab-value = lv_total.
MODIFY out_tab transporting fields value.
ENDIF.
ENDFORM.
Hope it helps!!
