KSEF-BUS-127 INFERRED Error
Invalid boolean field format
Niepoprawny format pola logicznego
Problem
A boolean field on the invoice has a value other than '1' (Yes) or '2' (No). In FA(3), boolean fields (e.g. P_16, P_17, P_18, P_18A) must have one of these two values when present.
How to Fix
Check boolean fields (e.g. P_16, P_17, P_18, P_18A) — each should have value '1' (Yes) or '2' (No) when present. Values like 'true', 'false', 'tak', 'nie', '0' are rejected by the XSD (TWybor1_2).

Boolean fields P_16–P_23 (XSD type TWybor1_2)
Pola logiczne P_16–P_23 (typ XSD TWybor1_2)
“Fields P_16 to P_23 accept only values "1" (yes) or "2" (no). XSD type TWybor1_2 restricts the value to enumeration {1, 2}. Brochure FA(3), Table 29 lists annotation fields with this type: P_16 (cash method), P_17 (self-billing), P_18 (reverse charge), P_18A (MPP), P_19 (exemption), P_22 (EU), P_23 (related parties).”
