Dynamic currency conversion running total

[stefans2403]

Hi all,

I'm trying to calculate running total of a column while at the same time I'm doing currency conversion.

Here is my data:

So, for example here I have a date slicer placed on 01/31/2017. In this case, 2015 amount should divide 'Amount' with rate of a last date in that year or slicer date (for 2015 it should take rate of 12/31/2015, for 2016 rate of 12/31/2016 and for 2017 rate for 01/31/2017). That is what I got in 'Amount EUR per Year' column, but for some reason Total is wrong:

So basically at the end I need to calculate running total of 'Amount EUR per Year' column:

How could I manage this?

Here is the sample PBIX file.

Thanks!

This is what I managed to calcuate:

Amount Cumulative = 
CALCULATE (
    SUM('dwh FactGLbs'[Amount]),
    FILTER ( ALLEXCEPT(DimDate,DimDate[Year] ), 'DimDate'[Date] <= MAX ( 'DimDate'[Date] ))
)

and conversion:

Amount Cummulative EUR = 
VAR CurrentExchangeRate =
    CALCULATE (
        MAX ( 'dwh DimCurrencyExchangeRate'[Exchange Rate] ),
        LASTNONBLANK (
            DimDate[Date],
            MAX ( 'dwh DimCurrencyExchangeRate'[Exchange Rate] )
        )
    )
RETURN
    DIVIDE( [Amount Cummulative], CurrentExchangeRate )

but the thing is that I am not getting desired ExchangeRate.

Using this formula, for example, Running Total for 2016 is calculated using SUM('dwh FactGLbs'[Amount]) but is dividied by ExchangeRate of 31/12/2016.

I need Amount Cummulative EUR for 2016 to be calculated like: (SUM('dwh FactGLbs'[Amount] for 2015) * ExchangeRate of 31/12/2015 )+(SUM('dwh FactGLbs'[Amount] for 2016) * ExchangeRate of 31/12/2016 ), etc.

Does anyone have an idea?
