Notes

A correction invoice is issued by suppliers to correct errors in a previously issued e-invoice, apply discounts, or account for returns. From a structural perspective, the Polish B2B system offers two distinct methods for issuing correction invoices.
1. Provide Original and Corrected line.
  A correction invoice includes two versions of the same line item: the original incorrect line showing negated amounts, prices, and quantities that need correction, and the corrected line containing the updated amounts, prices, and quantities. The invoice total reflects the difference between the original and corrected invoice.
2. Provide one delta line. This option is currently not supported.
  In this case, the invoice line displays the differences in amounts, prices, and quantities between the original incorrect data and the corrected data. Negative values indicate prices that were initially too high or goods that were returned. Positive values indicate prices that were initially too low.
