PEPPOL-EN16931-R130 Price base unit code must match invoiced quantity unit code

Under Peppol rule PEPPOL-EN16931-R130, whenever an invoice line specifies an item price base quantity unit of measure code in BT-150 (unitCode on BaseQuantity), its value must be identical to the invoiced quantity unit of measure code in BT-130 (unitCode on InvoicedQuantity). In electronic trade, mixing different units of measure on the same line (such as billing quantity in "H87" pieces while pricing in "KGM" kilograms without conversion) creates ambiguity in automated pricing calculations. Both unitCode attributes must share the same UN/ECE Rec 20 / Rec 21 code.

XRechnung 3.0

Context and Significance

Mismatched unit codes between invoiced quantity (BT-130) and price base quantity (BT-150) violate Peppol rule PEPPOL-EN16931-R130.

Solution

In your ERP product catalog or unit conversion settings, align the unit of measure of the price base quantity with the line item billing unit. In UBL 2.1 syntax, ensure that <cbc:BaseQuantity unitCode="H87"> shares the exact same unitCode attribute as <cbc:InvoicedQuantity unitCode="H87">. In UN/CEFACT CII syntax, ensure that <ram:BasisQuantity unitCode="H87"> under <ram:NetPriceProductTradePrice> matches <ram:BilledQuantity unitCode="H87">. If 1:1 unit pricing applies, you may omit the BaseQuantity tag entirely.
