Explanation
When yousubmit a "payment process request", you can enable the Apply credits up to zero amount payment option. Enabling the option causes the payment process to apply credits when the credits reduce the payment amount below zero.
The following scenario illustratethe impact of this option.
Credit Amount Greater Than Invoice Amount
An invoice for 200 USD and a credit memo for 225 USD are due for payment.
The following table describes the payment processing that occurs based on the setting for the Apply credits upto zero amount payment option.
Assume that the "Apply Credits Up to Zero Amount" option is enabled.
Payment processing applies 200 USD of the credit memo to the invoice and creates a payment for 0 USD. The remaining credit is 25 USD.
