dynamic computation based on slicer

[Aleli]

Hi,

Can anyone suggest a simpler way to show converted amount to USD?

Currently, here's what I have:

Table 1 - COUNTRY, YEAR, MONTH, INCOME (in local currency)

Table 2 - YEAR, MONTH, LOCAL CURRENCY, EXCHANGE RATE (to convert local currency to USD)

Year Slicer from 2013 to 2017 -- Whatever is selected will be treated as "CURRENT YEAR" (CY), and will be compared against the "PRIOR YEAR" (PY = CY-1) income.

My goals:

Present CY and PY figures in a bar chart. X-axis=COUNTRY, Y-axis=INCOME

Add a new slicer that will give the user an option whether to use current year or prior year exchange rate

I believe only the CY figure should change, depending on the exchange rate year slicer.

Many thanks!

There are a few approaches, depending on your data.

If you have monthly data for all months and every month as exchange rate data too, you can do this.

create a calendar table that contains the months (with a unique ID)

Join the 2 data tables (Table 1, Table 2) to this one common calendar table.

When you filter from the calendar table by month, both table 1 and table 2 will be filtered.  You can then "harvest" the exchange rate with something like this

Rate To Use = Max(Table2[Exchange Rate])

As long as you only have every month covered once and always once, this formula will give you the exchange rate.

To work out the conversion, you could use something like this

Income Local Currency = sum(table1[Income])

Converted Rate = sumx(Calendar,[Income Local Currency] * [Rate To Use])
