Sales orders in foreign amount - exchange rate depends on the contract with the bank
We are a Euro based Cie selling in multiple currencies: GBP, USD, ...
Due to the fact that some sales take a lot of time between the sale and the payment we handle our currency exchange risks by fixing the currency rate with a banking contract.
Since there is no standard way to change the currency rate on the order once the order is entered I was wondering how others handle this?
Any ideas are much appreciated.
