BR-37

Each Document level charge (BG-21) shall have a Document level charge VAT category code (BT-102).

What does this rule mean?

A document-level charge (BG-21) is missing its VAT category (BT-102).

Every charge must state its VAT category so it feeds the VAT breakdown correctly.

BG-21
Document level charges (group)
BT-102
Document level charge VAT category code
Official rule message (standard)

Each Document level charge (BG-21) shall have a Document level charge VAT category code (BT-102).

Where the rule applies

Syntax: CII · UBL

The same rule, expressed twice: UBL and CII name the same fields with different paths. Running a CII file against the UBL rules is why you get errors that mean nothing.

UBL

  • /ubl:Invoice/cac:AllowanceCharge[cbc:ChargeIndicator = true()] | /cn:CreditNote/cac:AllowanceCharge[cbc:ChargeIndicator = true()]

CII

  • //ram:ApplicableHeaderTradeSettlement/ram:SpecifiedTradeAllowanceCharge/ram:ChargeIndicator[udt:Indicator='true']

Technical test

The rule passes when this Schematron expression holds true:

(../ram:CategoryTradeTax[upper-case(ram:TypeCode) = 'VAT']/ram:CategoryCode)
