Such types are really a big constraint that prevent us to generate mixed documents (half invoice and half credit note). So the idea will be to migrate the credit note to negate the quantity and keep in type only 'in' / 'out' (aka 'supplier' / 'customer'). The only difficulty will be for the sequence. Until now, we have the possibility to use different sequences for invoice and credit note. I think the way to manage such change will be to warn early enough users that such configuration will no more be possible in the future and so people should configure the next fiscalyear by using unique sequence for both types in prevision of the future migration.We need both sequences in Spain as it is a legal requirement [1]. Yet, it should not be all that difficult to choose the sequence depending on the sign of the invoice.So what do you think?It has some advantages and simplifies things. Specially makes supporting the negative quantities/amounts from sales much simpler.

If I understand correctly this document in fact there is other cases where different sequences are mandatory (rectifications, intragroup invoices, something about the travel agencies, etc). So wouldn't it be more clever to put the sequence on the invoice andlet the user decide what is the right sequence to use?
The question that arise is how can the system infer the correct sequence when generating the invoice from another document. In your case it seems to be linked both to the kind of operation (rectifications) or party involved (intra group) or maybe even other things (I saw a mention of "natural year" (año natural) but I don't understand it) … -- Nicolas Évrard - B2CK SPRL E-mail/Jabber: [email protected] Tel: +32 472 54 46 59 Website: http://www.b2ck.com/
