Non-Monetary Bank Account
If you enter a foreign currency voucher and you or the system assigns a non-monetary bank account, the bank account currency must be the same as the base currency of the voucher.
For example, assume the company base currency is USD. You enter a foreign currency voucher in EUR. The bank account associated with the voucher must have a currency of USD.
You can change the bank account to any non-monetary bank account that has the same domestic currency as the voucher company. You can then pay any foreign currency voucher from that bank account, provided it is in the transaction currency of the voucher.
