Why do I have to allocate credit notes against an invoice?
A supplier shows open invoices and credit notes, I want my remittance to show the invoices and credits as separate items, so when I am making a payment I want to be able to select open credit notes to be included in the payment and shown as such.

Hi Stephen,

We originally thought that it would be confusing for novice users to see
credit notes listed when they were recording invoice payments which is why
we require credit notes to be allocated to the invoice as a separate
transaction. However, I can see why it is more convenient for advanced
users to be allocate to both invoices and credit notes - I'll note that as
a feature request in our development system.

It would be much more useful !
Many thanks
