Invoice date gap too large (P_6 vs P_1 > 30 days)

Zbyt duża różnica między datą sprzedaży a datą wystawienia

Problem

Gap between delivery/service date (P_6 — sale date) and invoice issue date (P_1 — issue date) exceeds 30 days. The invoice should be issued closer to the transaction date.

How to Fix

Check the dates on the invoice — the issue date (P_1) and sale date (P_6) should not differ by more than 30 days.
