Final settlement invoice (ROZ) must reference prior advance invoices
Faktura rozliczeniowa (ROZ) wymaga referencji do faktur zaliczkowych
Problem
Settlement invoice (ROZ) has no FakturaZaliczkowa section referencing an earlier advance invoice. Where advances did not cover the full payment, Art. 106f sec. 3 of the VAT Act requires the KSeF numbers of the advance invoices; where no advance invoice was issued (e.g. payment and delivery in the same month, Art. 106b sec. 1a), the missing reference is acceptable.
How to Fix
If an advance invoice was issued earlier, link the settlement invoice to it by entering its KSeF number in the FakturaZaliczkowa section. If there was no advance, the ROZ marker without this section is correct — the warning may be ignored or the rule disabled.
