Vendor Amount
The field shows the amount you have applied using the grid on the Payment Entry form, unless you are entering a prepayment.
In multicurrency ledgers, the payment amount is converted from the vendor currency to the bank currency using the exchange rate information contained on the Rate Override form. To change the exchange information for a selected payment, open the Rate Override form by clicking the Rates button at the bottom of the Payment Entry form.
If you are entering a prepayment, you use this field to type the amount you are prepaying. If you have a multicurrency ledger, enter the amount in the vendor currency — not in the bank currency. The amount is converted to the bank currency for the check amount, using the rates shown on the Rate Override form.
