Unit net price must be positive
Cena jednostkowa netto musi być dodatnia
Problem
The unit net price (P_9A — net price) on the invoice line must be positive. A negative or zero price is not acceptable on standard invoices.
How to Fix
Correct the unit net price on the indicated line — it must be greater than zero. Negative prices are allowed only on correction invoices.
