You have a down payment request and supplier invoice posted in foreign currency.
After you clear the down payment request with a payment, system generates the down payment in your company currency.
Since the exchange rate used in down payment and supplier invoice are different, when you clear down payment with supplier invoice, they may be balances.

There are two options:
Option A: You can use payment difference in the clearing of down payment and supplier invoice.
Option B: In case you insist to avoid any payment difference posted in clearing, please cancel the supplier invoice. Maintain the exchange rate as the same as used in down payment (Just the clearing of down payment request with payment).
Create the supplier invoice again and clear it with the down payment.
