Wrong Column Totals (Matrix)

[marcofalzone]

I wrote a DAX measure that convert a YTD balance to a common currency (EUR). The measure works well when a single company is selected (1 currency) but generates a wrong Total column when I try to select 2 or more companies (currencies).

Act_Eur_Ytd = 
VAR NUMERATOR = [Act_Lc_Ytd]
VAR DENUMERATOR = CALCULATE(AVERAGE('Facts'[Avg_Ytd_Fx_Rate]), ENDOFMONTH('Calendar_Table'[Date].[Date]))
RETURN ROUND(DIVIDE(NUMERATOR,DENUMERATOR),2)

Example:

The expected output of the matrix is:

The current behavior of measure Act_Eur_Ytd is:

When Company 1 alone is selected, Numerator properly sums EUR amounts and divides them by 1

When Company 2 alone is selected, Numerator properly sums CNY amounts and divides them by 0.1

When both companies are selected, Numerator sums EUR + CNY (wrong) and divides by an average (wrong).

The exchange rate is linked to calendar, in order to convert at the latest average rate of the selected Month/Year.

In order to give a better context, I attach the real life example, with source data.

I appreciate the help of the community to properly correct the syntax of my DAX measure.

Thank you.

Hi , @marcofalzone 

Thanks for your provided sample .pbix file .

According to your description, the total is wrong because it not get the summation of the columns.

You can try to use this measure :

Act_Eur_Ytd Test = 
var _t =ADDCOLUMNS( CROSSJOIN(VALUES('Company'[CompanyString]), VALUES('PL_Mapping'[PLRowDescr])) , "Act_Eur_Ytd" , [Act_Eur_Ytd])
return
SUMX(_t ,[Act_Eur_Ytd])

Then we can get the right total:

Thank you for your time and sharing, and thank you for your support and understanding of PowerBI!
