foreign wire payments

Folks,

Can I know how to handle the below request?

A supplier will invoice us in a foreign currency and we book the payable on our ledger in the foreign currency. When payment is due, we create an FX wire in the Bank's CashPro system. The payment value is input in the foreign currency and we are given a conversion rate. Bnak transfers the payment in the foreign currency and debits our bank account for the USD value.

Please let me know how to configure this.
