Currency Conversion Calculation: use most recent conversion rate to replace rate in future

[Anonymous]

Hi everyone,

I am creating a measure to convert currency. The logic of currency conversion is that if the opportunity has a future close date, then use the most recent exchange rate.

But my measure doesn't show any conversion rate when there is a future close date.

ConversionRate = CALCULATE(IF(ISBLANK(CALCULATE(FIRSTNONBLANK(VALUES('Dated Conversion Rate'[ConversionRate]), 'Dated Conversion Rate'[ConversionRate]), FILTER('Dated Conversion Rate','Dated Conversion Rate'[StartDate] = FIRSTDATE('Opportunity'[CloseDate]) && 'Dated Conversion Rate'[IsoCode] = FIRSTNONBLANK('Opportunity' [CurrencyIsoCode], 'Opportunity' [CurrencyIsoCode])))), LOOKUPVALUE('Currency Type'[ConversionRate], 'Currency Type'[IsoCode], FIRSTNONBLANK('Opportunity' [CurrencyIsoCode], 'Opportunity' [CurrencyIsoCode])), CALCULATE(FIRSTNONBLANK(VALUES('Dated Conversion Rate'[ConversionRate]), 'Dated Conversion Rate'[ConversionRate]), FILTER('Dated Conversion Rate','Dated Conversion Rate'[StartDate] = FIRSTDATE('Opportunity'[CloseDate]) && 'Dated Conversion Rate'[IsoCode] = FIRSTNONBLANK('Opportunity' [CurrencyIsoCode], 'Opportunity'[CurrencyIsoCode])))))

CloseDate is located in the opportunity table; NNARR revenue is located in the opportunity product table and Startdate is the key to link opportunity table and date table.

The date models between table used:

Thanks!

Hi  @Anonymous ,

Your formula is too poorly readable,  so I suggest you split it into multiple measures and check for problems.
