Unit gross price must be positive
Cena jednostkowa brutto musi być dodatnia
Problem
The unit gross price (P_9B — gross price) on the invoice line must be positive. A negative or zero gross price is not acceptable on standard invoices.
How to Fix
Correct the unit gross price on the indicated line — it must be greater than zero. Negative prices are allowed only on correction invoices.
