Cumulative sum measure

Hello,

 I have the following cumulative sum measure which is built like that:

ArticleRank = RANKX(ALL(vdimarticle_v2),[Calculation KPI],,DESC,Dense)

PercentageofTotal = 
var TotalKPI = CALCULATE([Calculation KPI],ALL(dimarticle))
RETURN
 DIVIDE([Calculation KPI],TotalKPI)

CumulativeSumTop102 = 
var Top10Table = CALCULATETABLE(
                                  dimarticle_v2,
                                  FILTER(
                                    ALL(dimarticle_v2),
                                    [ArticleRank]<=30
                                  )
)
var CurrentArticleSum = [PercentageofTotal]
RETURN
    CALCULATE(
        [PercentageofTotal],
        FILTER(
            Top10Table,
            [PercentageofTotal]>=CurrentArticleSum
        )
    )

It works as follows, it ranks articles based on quantity and then it takes quantity of the first article and divides it by total quatity, for second article, it takes quantity of the first article + quantity of the second article and then  divides it by total quantity etc.

But I have problem if I filter sth on table dimarticle, because than measure shows incorrect numbers, do You know how to avoid this situation so allow users filtering on the table and make this cuulativesum be adjusted accordingly to the filters?

Thank you in advance,

Natalia
