DAX Measure (Dynamic Cumulative Sum)

[Anonymous]

I want to create the cumulative total based on the rank (in this case a Measure Count), unfortunately I can't get it to work with this attempt. I always get the total and not the running total.
Do you have any idea how to do it?

Lines_Cum = 

VAR CURRENTRANK = [COUNT]

RETURN

SUMX(

    FILTER(

        ALL(FAKTWA_DAT),

        Currentrank <= MAXX(FaktWA_DAT,[Count])

        ),

        [LINES]

)

COUNT = RANKX(ALL(FaktWA_DAT),[AS_Index],,ASC,DENSE)-1

@Anonymous Try:

Lines_Cum = 

VAR CURRENTRANK = [COUNT]

RETURN

SUMX(

    FILTER(

        ALL(FAKTWA_DAT),

        [Count] <= Currentrank 

        ),

        [LINES]

)

unfortunately it didn't work, I found another solution. (Index made in PQ and then SUMX with AS_LINES (dynamic Lines) but it only works for counts smaller than 1000. After that, the working memory has problems and displays an error message. 

Lines_Cum = 

SUMX(

        

    FILTER(

        ALL(FAKTWA_DAT),

        FaktWA_DAT[Index] <= MAX(FaktWA_DAT[Index])

        )

    ,[AS_Lines]

)
