how does AR premier handle multi currency invoices

I need to understand multi currency, Our unpaid stock invoices are  recording @ one Euro rate from the inventory account when the stock in being sold from inventory at the value of the invoice in the system unpaid as it is unpaid. What happens in myob? once the invoice is paid with a different Euro currency value and balance of the stock that that has yet to be sold in MYOB? 

Does it take the invoice completely into stock at the initial currency converted (to AUD) rate, and no change occurs when the invoice is paid at a different value?
