Multiple Currencies

[David Somers Harris]

What is the recommended way for keeping track of finances in multiple
currencies?

I have assets, liabilities and expenses etc. in two countries, and came up
with a hierarchy like this:

Assets
- Canada
- - Current Assets
- - Etc.
- Japan
- - Current Assets
- - Etc.
Expenses
- Canada
- - Clothing
- - Etc.
- Japan
- - Clothing
- -Etc.
Etc.

The problem is though that when I want to run reports (e.g. expense report)
it shows everything, but I'm only interested in one country at a time. Is
there a better way of doing this, perhaps from an account hierarchy
perspective or a reports setting perspective?
