After you have set up your bank accounts, you may need to post a banking transaction involving an account with a currency code.
Open the General Journal window.
On a journal line, enter the account with the currency code first in either the Account No. field or the Bal. Account No. field.
Enter the amount in the Amount field with or without a sign; an amount without a sign is a debit, and an amount with a minus sign is a credit.
Click Posting, Post.
