[Dolibarr-user] credit note / cancellation to Suppliers?

[Torsten Appelhagen]

Hi again,

Recently we bought something with prepayment. I entered an order, 
created the invoice, paid, and did the bank transaction.

So far so good.

But after a few days the supplier told us he is unable to deliver and 
we'll get our money back (which happened).

Now I need to do a formal cancellation of the supplier's invoice with a 
new financial transaction to clean up, but I don't find any option to do 
so - where is it or how is this meant to be done?

A side question would be handling of credit at a supplier. Last month an 
invoice was charged twice, and we agreed to set it up with their next 
invoice.
Seemlingly I can't do so also. I made a "dummy invoice" now to have 
balances in sync with the bank account, but I will have to remember it 
and reopen/correct this invoice to be the next "real" one...? :(
