Pivot Table

[kprotrka]

I have one pivot table where I am using following formula:

sum(Aggr(Count(DISTINCT {<[Abrechnungsplanhilfe.VORRAT]-={'Endabgerechnet', 'Erledigt'}>} [Abrechnungsplanhilfe.VORRAT]), [Abrechnungsplanhilfe.OIDVARTKOMBI]))

The total result is OK, but wrong splitted. For example,offen i wrong at the beginning, but after the filtering the offen I get the right value.

First screenshot is wrong and the second one is correct.

What is the reason for that?
