3825122 - How are Exchange Rates Calculated for My Audit Rules?

I would like to be able to set a daily amount limit for my employees that is based on the country where they are traveling.  For example:  If an employee travels to the US, their total daily spend on meals should be $75.00.  When they travel to Germany, their total daily spend should be 50.00 EUR.  And, so forth.  I have added currency to my Amount-Daily total audit Rule, but it is not triggering correctly.  How can I set this up so that travelers can have different daily spend limits in different countries?

We have an Audit Rule set up that will stop users from spending more than their daily limit on meals, and it doesn't seem to work when they travel to another country. The Audit Rule is stopping them from submitting, but they are within their daily limit. How are these exchange rates calculated? , KBA , CON-CA-ADM , Administration , Problem
