Problem with totals

[Hitman1981]

Hello,

I am an amateur, and I am approaching qlikview, I  am having a problem with the totals.

The data is calculated with a simple sum().

As you can see in the image there is a sum problem, the strange thing is that the total is right, while the lines are wrong, because there are products that are added both in the first line and in the second row. 

what I ask, if it is possible to repartition the total in the rows in percentage and never exceeding the "CARICATO" column.

I apologize in advance for my basic level English.
