We are adding weight or volume based charges automatically on Customer orders when new customer order line is created. There is charge type and charge price per liter or kg defined in Sales Charge Type. Charge price in Sales Charge type is always defined in Site base currency. We have customers that are ordering in different currencies. For those we have agreed fixed charge prices per kg or liter in the currency customer is using. How can we defined those other currency charge prices. In standard solution it is always doing charge price conversion from base currency to order currency with daily exchange rate. In this case that order currency charge price is not fixed. It is changing every day.
