Base quantity MUST be a positive number above zero.

Why it fails

The item price base quantity (BT-149) is zero or negative.

How to fix it

It must be greater than zero. Omit it entirely when the price is per single unit rather than sending 0.

What the validator checks

CII — context —

not(ram:BasisQuantity) or xs:decimal(ram:BasisQuantity) > 0

UBL — context —

not(cac:Price/cbc:BaseQuantity) or xs:decimal(cac:Price/cbc:BaseQuantity) > 0
