Using LOOKUPVALUE for currency conversion
Hi thanks for readingI'm using 3 tables for this operation.
Date table
Exchange - to USD
| Currency | Date | Value |
| GBP | October of 2021 | 1.34 |
Data
| Coin | DateData | Income |
| GBP | October of 2021 | 200000 |
The 3 of them are related (One direction).
To accoplish this I have the following calculated column:
USD = DIVIDE(Data[Income],
LOOKUPVALUE(Exchange[Value],
Exchange[Date],Data[DateData],
Exchange[Currency],Data[Coin]
),0
)
But is working correctly just on a few rows, most of them are 0.
I made another column just with the LOOKUPVALUE and returns blank rows, hence the zeros.
Nonetheless I checked many examples and the combination of date and currency do exist.
I trimmed the GBP' field in both tables and nothing changed.
Any ideas are welcomed.
Best regards.
Anonymous , for the missing records, means blank or 0, do you have a conversion rate for that date. I doubt that at first .
The second data table might have timestamp , that can be checked by changing data type to datetime and use format with time, there should not be any time other than 12 AM
if that is case create a date like
Date = [datetime].date
or
Date = date(year([datetime]),month([datetime]),day([datetime]))In power query
DateTime.Date([datetime])
Can you share a pbix after removing sensitive data.

Thanks amitchandak, evidently the issue was in the dates. So I just transformed both to test and the Dax expression worked.
Best of luck!
