>> No, you haven't done anything wrong. Every transaction has a transaction currency that's used to balance the transaction. That currency is determined by the account from which the transaction is created, and in this case it's EUR, so GnuCash needs to know the value in EUR of the bank charge. Just use the same exchange rate that you used to convert the EUR payment to GBP.


Read it again: "That currency is determined by the account from which the TRANSACTION IS CREATED." Once the transaction is created its currency is immutable. It matters not a whit in what account one modifies it from.
