Weighted average

[#1]

Hi all,

I have build a report which works fine, except fot the total column.

Report purpose: I have 2 trucks which bring goods to my customers. I need to know how well they are loaded, so that they are not driving around only half full.

Here is the problem:

Dimension: TruckID

Expr1: sum(DeliveredWeight)

Expr2: total count(DISTINCT VoyageNr)

Expr3: MaxLoad                                                  --> this comes from a seperate table where I my TruckID is unique key

Expr4: sum(DeliveredWeight) / total count(DISTINCT VoyageNr) / MaxLoad

This all works fine, except for the totals colums. For Expr4 the result is wrong.

This is the table:

The total where it says 24,67% should be 46,83%

(16 * 9 + 20 * 14) = 424

198,558 / 424 = 46,83

I've been trying different things with aggregation, but i can't get this result.

any help will greatly appreciated.

Kind regards,

Yves
