Invoice correction design

[Łukasz Drozdowski <drozdowskilukasz@gmail.com>]

Hello everybody.

I'm new here and ubl is new subject to me so I've got basic question. How do you desing Invoice correction (or adjustment may be better word)? I mean the document which is referenced to original invoice number and doubles invoice fields: original value and new value.

Let me know if I can find this information somewhere online.

Best regards,
