Convert currency

I need to convert the 'amount' column in the below table to EUR (currency is GBP at the moment), and then to merge the table with another that is already in EURO.  So far I have not been able to do ...

    This will work if you get rid of all of your non-GBP exchange rates. Do you need those? If you do, sure some more DAX magic can get you there.

     

    Column = LOOKUPVALUE(ExchangeRates[ExchangeRate],ExchangeRates[CurrencyCode],"GBP",ExchangeRates[StartTime],MAX(ExchangeRates[StartTime]))

    Oh wait, here is the additional DAX magic that will let you keep your other currency codes.

     

    Column = LOOKUPVALUE(ExchangeRates[ExchangeRate],ExchangeRates[CurrencyCode],"GBP",ExchangeRates[StartTime],CALCULATE(MAX(ExchangeRates[StartTime]),ExchangeRates[CurrencyCode]="GBP"))

Hello Greg_Deckler,

 

Sorry for not answering before, my client started requesting things afar from the agreement. 

 

The data are as follows:

 

Fact Table with sales by invoice line:

https://www.dropbox.com/s/hz5nc6kqda4wbv9/Daily%20Revenue%20by%20invoice%20item%20Original.xlsx?dl=0

 

Exchange rate table:

 

DateUSD
01-ene-1919.6512
02-ene-1919.6512
03-ene-1919.5878
04-ene-1919.6073
05-ene-1919.6073
06-ene-1919.6073
07-ene-1919.4902
08-ene-1919.3479
09-ene-1919.3479
10-ene-1919.2456
11-ene-1919.1236
12-ene-1919.1236
13-ene-1919.1236
14-ene-1919.1236
15-ene-1919.0064

 

In excel I would do it just easily with =vlookup convert all sales in MXP to USD based on the invoice date and bring the sales already in USD to the same column to have a total in USD, e.g.

https://www.dropbox.com/s/jvwex5u8o0l7mo9/Daily%20Revenue%20by%20invoice%20item.xlsx?dl=0

 

In this way the last column would show Sales in USD converted at the invoice date, not at month end.

 

When I use LOOUPVALUE my problem is when assigning the current date in SEARCH VALUE doesn't recognize the row context and get the error: "A table of multiple values was supplied where a single value was expected".

 

LOOKUPVALUE (
    EXCHANGERATES[RATE],
    EXCHANGERATES[DATE], DATE ( 2019, 1, 12 ),
    EXCHANGERATES[CURRENCY], "MXP"
)
 
Could you please advice?
 
Thanks a lot,
 
Fernando

    Hi Greg_Deckler,

     

    So as you can see, my intent here is to be able to convert each individual invoice based on its date's exchange rate, not one final convertion at month end with only one exchange rate.

     

    Could you advise on a way to do it?

     

    Thank you for your help.

     

    Fernando

      Hello Greg_Deckler,

       

      Sorry to insist. I'd just only like to know if there is a way I can solve my problem of currency conversion in Power BI.

       

      Thanks and regards,

       

      Fernando
