My accountant tells me in Belgium, nobody does it but he can not say if it was forbidden. Indeed it is the quite logical otherwise there will be any notion of debit/credit because it can be replaced with positive/negative. Also that's why the credit note is called a credit note because it does credit. > >> For me the current cancelation functionality can be removed as it will > >> now implemented by a credit note (which is defined by a record with a > >> negative total amount).

It is needed otherwise I can not use Tryton in Belgium at least. More over, it is been 7 years Tryton does credit without any complaint. Negative debit/credit is the *special* case. In my accounting courses, my teacher never spoke about negative debit/credit indeed if I had put one in my exercise, I would have failed. -- Cédric Krier - B2CK SPRL Email/Jabber: cedric.kr...@b2ck.com Tel: +32 472 54 46 59 Website: http://www.b2ck.com/
