Cumulative Sum - Dimension Problem

[#1]

Hi, friends from QlikView community. I'm a newbie here, but I trained day or two with cumulative sums.

I have a dataset with 6 dimensions:

- Year (Rok): 2014, 2013,02012 ...

- Month (Obdobie): 1.12.2014, 1.11.2014, 1.10.2014 ....

- Series (Seria): Plan / Reality (Uctovnictvo)

- Code (Kód): AZZZ, B07VRA, D01TSC ... - types of incomes and costs

- Phase (Faza): B01REAL, B02MIMOREAL .. - codes of Phases, in which incomes/ costs occur

- Amount (Ciastka) in EUR

I designed a dashboard (sheet) with a cumulative chart of a calculated expression (D01TSC-AZZZ)/AZZZ.

Expression is here:

((Rangesum(Above(total Sum({$<[Kód]={D01TSČ}>}Čiastka),0,RowNo(total))))

+(Rangesum(Above(total Sum({$<[Kód]={AZZZ}>}Čiastka),0,RowNo(total)))))/

(-1*(Rangesum(Above(total Sum({$<[Kód]={AZZZ}>}Čiastka),0,RowNo(total)))))

Everything works fine (I'm very proud of me :-)), but only when I select only one of the crucial dimension Series.

If I select both (Plan AND Reality), data are not identic with previous situation.

Situation Nr.1: Series = Plan, Cumulative result for Dec 2013 = 18,00% - OK

Situation Nr.2: Series = Uctovnictvo, Cumulative result for Dec 2013 = 47,28% - OK

Situation Nr.3: Series = Plan AND Uctovnictvo, Cumulative results for Dec 2013 differ from above

The problem causes something wrong in manipulating dimensions in the expression, but I can't find it out 😞

Can U help me, pls. ?

Thanks in advance.
