Cancellation already exists, it is not activate on the posted customer invoice (but on supplier) because it is not allowed in every country. Of course, a standard module that makes the fine tune to activate it is welcomed. > Maybe these informations will help you to figure out if it is really > possible to remove the invoice and credit note type and only to keep the > out/in part. > > I took a look into the SAP documentation and i found there the even 8 > cases[4]: > ininvoice, outinvoice. increditnote, outcreditnote, > ininvoicecancelation, outinvoicecancelation, increditnotecancelation, > outcreditnotecancelation As already stated having invoice/credit note distinction prevents to put in the same document both kind of lines. And in case of such mixed document it is name is not so trivial to determine. But we can keep the numbering distinction using the total sign. About the cancelation sub-type, I don't think we have to create a new document (record in invoice table) for that. The current design is to create a cancelation move linked to the invoice. If a specific number is needed for customer cancelation, I guess the module (I talk above) could add an other field to hold the number and the invoice report could be customized to use this number. > I think we should investigate this topic really precise before making a > decision. > > To your questions about the sequences i can say that it is common to > have different sequences for credit notes and invoices but that it is > (not yet) a legal requirement.

Yes it seems any way that we will have to keep for migration purpose the two sequence field invoice/credit note. Just like we will have to keep it for the taxes. -- Cédric Krier - B2CK SPRL Email/Jabber: [email protected] Tel: +32 472 54 46 59 Website: http://www.b2ck.com/
