odd compute value

I'm getting some very exaggerated numbers from the following compute statement.
COMPUTE MARGIN_GOAL/P11BM = (PROJECTED_SALES * GM_PERC); AS 'Margin,Goal $'

If I run it in SQL against our iSeries, I get a very small number compared to the number webfocus is showing.


Here's an except from my master file, if it's any help. I figure it may have something to do with this packed decimal value.

FIELDNAME=PROJECTED_SALES, ALIAS=PROJECTED_SALES, USAGE=P22.6, ACTUAL=P11,
MISSING=ON, $
FIELDNAME=GM_PERC, ALIAS=GM_PERC, USAGE=P7.3, ACTUAL=P8,
MISSING=ON, $

Jason

can you post the whole script you run?
both the SQL statement and the FEX.

As Frank asks. If you are computing, this occurs after an aggregation occurs if any 'by' statements, and if you have joins involdve you could be 'multiplying the data occurances.

Leah's may be right,
I think that what could be happening is it's aggregating PROJECTED_SALES, then aggregating GM_PERC, then multiplying. kind of a silly order of operations. If this is true, is there any way to make it do the aggregation on the multiplied value?

my fex is massive (1000 loc), but here's a short excerpt, I hope it gets the point across.
TABLE FILE MATRIX_ORDERS_TBL
SUM
EXT_SALES_DOLLARS/P11BM AS 'Sales,Actual'
COMPUTE MARGIN_GOAL/P11BM = (PROJECTED_SALES * GM_PERC); AS 'Margin,Goal $'
BY HIGHEST YEARMONTH AS 'Month'
yields 40,000,000,000 or so.

Sql:
SELECT
yearmonth,
sum(projected_sales*gm_perc)
FROM
SQLPROD.MATRIX_ORDERS_TBL
where
yearmonth = 200709
group by
yearmonth;

yields:
200709 5,379,209.191409199

I would like to see what the result in the FEX would be if you do

DEFINE FILE XXX
MARGIN_GOAL/P11BM = (PROJECTED_SALES * GM_PERC);
END

and then use the defined field MARGIN_GOAL in your request.

thanks for the thoughts folks. I went ahead and ran a performance monitor on the database to catch all the sql requests.

It shows the request as
SUM(PROJECTED_SALES)
SUM(GM_PERC)

SO, it's doing exactly as leah mentioned. I'm going to have to do the calculation at the row level of the database.

Thanks!
