Line net must not be negative on standard invoice
Kwota netto wiersza nie może być ujemna na fakturze standardowej
Problem
On a standard (non-correction) invoice, the line net amount (P_11 — net amount) is negative. Negative amounts are only allowed on correction invoices.
How to Fix
Correct the line net amount — negative amounts are not allowed on VAT, UPR, or ZAL invoices. If you need a correction, issue a correction invoice (KOR).
