Exchange Rate Conversion with Date Range

Hey FaizanRao ,

first of all you have to fix the data type in the CurrencyRate table. The value should be a decimal number, the dates should be dates.

Then you can add the following calculated column to the SalesData table:

Value in CurrencyRate =
VAR vRowCurrency = SalesData[Currency]
VAR vRowDate = SalesData[Date]
VAR vRowValue = SalesData[Value]
VAR vExchangeRate =
    CALCULATE(
        MAX( CurrencyRate[Value] ),
        ALL( CurrencyRate ),
        CurrencyRate[Attribute] = vRowCurrency
            && CurrencyRate[Date From] <= vRowDate
            && CurrencyRate[Date To] >= vRowDate
    )
RETURN
    vRowValue * vExchangeRate

Hi FaizanRao 

We couldn't show dynamc results in calcualted columns, try to build a measure to show dynamic results in table visual by slicer.

Firstly we build an unrelated Currency table by dax.

CurrencySlicer = VALUES(CurrencyRate[Currency])

Build a slicer by this table. Then create measures.

Value in Select Currency Rate = 
VAR _CurrencyRate =
    CALCULATE (
        SUM ( CurrencyRate[Rate] ),
        FILTER (
            ALL ( CurrencyRate ),
            CurrencyRate[Date From] <= MAX ( SalesData[Date] )
                && CurrencyRate[Date To] >= MAX ( SalesData[Date] )
                && CurrencyRate[Currency] = MAX ( SalesData[Currency] )
        )
    )
VAR _SelectCurrency =
    SELECTEDVALUE ( CurrencySlicer[Currency] )
VAR _SelectRate =
    CALCULATE (
        SUM ( CurrencyRate[Rate] ),
        FILTER (
            ALL ( CurrencyRate ),
            CurrencyRate[Date From] <= MAX ( SalesData[Date] )
                && CurrencyRate[Date To] >= MAX ( SalesData[Date] )
                && CurrencyRate[Currency] = _SelectCurrency
        )
    )
RETURN
    IF (
        HASONEFILTER ( CurrencySlicer[Currency] ),
        DIVIDE ( SUM ( SalesData[Value] ), _CurrencyRate ) * _SelectRate,
        DIVIDE ( SUM ( SalesData[Value] ), _CurrencyRate )
    )

Select Currency Rate = 
VAR _SelectCurrency =
    SELECTEDVALUE ( CurrencySlicer[Currency] )
VAR _SelectRate =
    CALCULATE (
        SUM ( CurrencyRate[Rate] ),
        FILTER (
            ALL ( CurrencyRate ),
            CurrencyRate[Date From] <= MAX ( SalesData[Date] )
                && CurrencyRate[Date To] >= MAX ( SalesData[Date] )
                && CurrencyRate[Currency] = _SelectCurrency
        )
    )
VAR _RMRate =
    CALCULATE (
        SUM ( CurrencyRate[Rate] ),
        FILTER (
            ALL ( CurrencyRate ),
            CurrencyRate[Date From] <= MAX ( SalesData[Date] )
                && CurrencyRate[Date To] >= MAX ( SalesData[Date] )
                && CurrencyRate[Currency] = "RM"
        )
    )
RETURN
    IF ( HASONEFILTER ( CurrencySlicer[Currency] ), _SelectRate, _RMRate )

Result is as below.

By default, measures will show values in RM rate and RM rate in date range.

If we select Currency in slicer, such as USD, measures will show values in USD rate and USD rate in date range.
