This doesn't say that invoice and credit note must have a different sequence. But of course, customization of the invoice numbering will still be possible.

So I don't see that it is a requirement to have separated sequences for each kind. -- Cédric Krier - B2CK SPRL Email/Jabber: [email protected] Tel: +32 472 54 46 59 Website: http://www.b2ck.com/
