Topic: Allocate Customer Payment module
I am confused about this allocate customer Payment option. There is a customer that is supposed to have a nil balance, but on checking it, it is showing -3500.00 which was allocated. how do I revert this and what is the function of allocate Customer Payment.
Secondly how do I make the forms update automatically. I am using ver. 2.3.11 and when I void a payment and try to post again, it will be telling me "the reference has been used before". how do I change this?
