When I select a vendor or vendor class to pay invoices with a particular Due Date, any credits are picked up without manually applying them to an invoice. I have used that option. I prefer top control the situation. I apply the credits to one or more invoices manually and then select the invoice(s) for payment.
I had a situation of GP2015 auto-applying, that the zeroed-out invoices did not show on the remittance stub.
