What does BR-AG-06 mean? In a Document level allowance (BG-20) where the Document level allowance VAT category code (BT-95) is "IPSI" the Document level allowance VAT rate (BT-96) shall be 0 (zero) or greater than zero.

Why did my invoice fail BR-AG-06?

In a document level allowance (BG-20) whose VAT category code (BT-95) is "IPSI" (code M), the allowance VAT rate (BT-96) must be zero or greater than zero. Missing or negative rates on an IPSI allowance are invalid. In UBL the rate is cac:AllowanceCharge/cac:TaxCategory/cbc:Percent.
