Total for currency converted values are wrong

[stevevincent16]

Monthly values for currency converted values are correctly shown in a matrix, but the total shown is wrong.

I have the local currency and other currencies to convert to. Everything is showing fine for local currencies, but the totals when converting to another currency using SUMX is wrong.

Here is the DAX I used:

**Prior Year Sales =

var _selectedYear = SELECTEDVALUE('Main Calendar'[Date].[Year])

var _priorYear = _selectedYear-1

var _priorYearSales = DIVIDE(CALCULATE(SUM(FactSales[Realized Sales]),

    ALL('Main Calendar'[Date].[Year]),

    YEAR(FactSales[Calendar Year / Month])=_priorYear),

    Scale[Scale Value])

var _convertedPriorYearSales =

CALCULATE(SUMX(

        'Exchange Rates Type C Extended With Future Rates',

        _priorYearSales*'Exchange Rates Type C Extended With Future Rates'[Exchange Rate]

    )+0, ALL('Main Calendar'[Date].[Year]), YEAR(FactSales[Calendar Year / Month])=_priorYear

    )

RETURN

SWITCH(TRUE(),

    SELECTEDVALUE('Format'[Format])="Local Currency", _priorYearSales,

   _convertedPriorYearSales

)

Hi , @stevevincent16 

According to your descrioption, the total in your Matrix is wrong in the _convertedPriorYearSales.

For this may cause the logic in your _convertedPriorYearSales calculation due to the filter context is difference, it is common in Power BI Desktop.

For to solve the wrong total , you can create a separate measure for the _convertedPriorYearSales:

convertedPriorYearSales =

CALCULATE(SUMX(

        'Exchange Rates Type C Extended With Future Rates',

        _priorYearSales*'Exchange Rates Type C Extended With Future Rates'[Exchange Rate]

    )+0, ALL('Main Calendar'[Date].[Year]), YEAR(FactSales[Calendar Year / Month])=_priorYear

    )

Then we can return this  instead of the _convertedPriorYearSales:
SUMX(VALUES('Table'[Month]),[convertedPriorYearSales ])

The 'Table'[Month] is the field you put on the table as the dimension.

If this method does not meet your needs, you can provide us with your special sample data and the desired output sample data in the form of tables, so that we can better help you solve the problem. (You can also upload you sample .pbix [without sensitive data] to the OneDrive and share with the OneDrive link to me ! )

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