BR-TMP-3 — EN 16931 rule

In a CII invoice, when the item price base quantity (BT-149) appears on both the gross and net price, the values (and their unit codes, BT-150) must be identical.

Rule: BR-TMP-3 — official EN 16931 / XRechnung rule
Severity: error
Detected by: tier 3 — KoSIT validator (authoritative)
Reachability: Only reachable when validating your own XML — normbill-generated documents cannot trigger it

The CII serializer writes BasisQuantity on the gross price when a gross/discount block exists, otherwise on the net price — never on both.

How to fix it

Align BasisQuantity and its unit code between GrossPriceProductTradePrice and NetPriceProductTradePrice.
