Cumulative Sum on the previous commun Columns

[RanOuerg]

Hello,

i need help to solve this issue , i've tested many codes but still not working on QlikView scripting, I have a data base with Country, Material , Qty

I need to calculate the cumulative Qty for all the previous rows if the key(Country, Material) is equal to the previous one than i do the sum like the example marked in Yellow here bellow row by row.

i used Peek but it doesn't work well for my case

Is there any solution to apply this rules in the chart area?

Thank you in advance!

In the Load script you can do a 

If(Country=Peek(Country) and Material=Peek(Material), RangeSum(Qty,Peek(CumulativeQty)), Qty) as CumulativeQty,

Just make sure that you have ordered the rows with an "Order By".

In a chart, you can do something similar using Above() instead of Peek().

Hello Henric,
