Hi
we had a customer who placed an order and paid in full - easy: prepayment & receipt payment against invoice.
Then same customer added to the order - multiple times which resulted in 3 further pre-payment invoices.
Now same customer has changed his mind and cancelled 2 of the additions = 2 invoices.
I have tried crediting but am getting following error message:
My questions:
a) how do I fix this. I understand it is a rounding error due to the multiple pre-payment invoices but it won't let me fix the problem.
b) can I actually - after a) - credit only one of the pre-payment invoices or do I need to credit the lot and re-post?
Thank you for your help
