A credit note must contain a reference to the original invoice, all corrected and corrective lines, and the reason for the correction. A corrected line is the original invoice line with a negative sign, and cannot be modified. A corrective line is the original invoice line with a positive sign, which can be modified.

A corrective invoice with a positive amount is treated as a credit note.
