sum of rows aggregation for subtotal

Dear QlikView community,

My issue is that I am trying to take into account the volumes of the different years for the price quality expression. I have enclosed my files, which might make it easier to comprehend the crux.

These are the steps that I am undertaking:

1. Calculate unitary prices (sales / volume) for both years, only taking into account prices of materials, which exist in both years. ==>works fine

2. Volume 2012 * Unitary Price 2011 (this column will then be used to calculate the overall price quality) . ==> works fine

3. Difference (2012 sales - Volume 2012 * Unitary Price 2011) ==>please see the different subtotals

4. Price Quality (Difference / Volume 2012 * Unitary Price 2011) ==>given that QV takes the wrong difference subtotal, my result at subtotal level is incorrect.

I should really get an aggregation on the difference column, which I could reuse for the Price Quality calculation.

My overall price quality for this scenario, as defined by step 4, should not be 8.70% (this is just from Excel) but rather:

1'300 / 4'785 = 27.20%

Basically you need to add a sum(aggr( ... , Material)) around your Difference expression. See attached qvw.
