Currency Exchange rate today only

‎02-24-2017 05:48 AM

Hello,

 

I have what seems to be a tricky task using DAX in Power BI.

 

I have 3 columns

 

Date

Amount

exchange rate

 

I need todays exchange rate only to calculate historical revenue. I dont want to use tomorrows exchange rate to calculate tomorrows revenue.

 

Amount / exchange rate (today) = Revenue

 

The 4th Column or Measure Revenue must only use todays exchange rate.

 

Please help I've tried everything and it seems over complicated.

Thank you for working this one out. Much appreciated. The following is a very good solution:

 

Ex Rate = MAXX(FILTER(ALL('price'),'price'[creation_time]=TODAY() &&'price'[currency]=EARLIER('price'[currency])),'price'[EX Rate])

 

followed by for if you have multiple currencies in your data when calculating revenue:

 

Current / Ex Rate =
var temp= MAXX(FILTER(ALL('price'),'price'[creation_time]=TODAY() &&'price'[currency]=EARLIER('price'[currency])),'price'[EX Rate])
return
IF('price'[strRefKey]= "DKK"||
'price'[strRefKey]= "NOK"||
'price'[strRefKey]= "SEK"||
'price'[strRefKey]= "ISK",'price'[Amount] / temp ,
BLANK()
)
