In a VAT breakdown (ibg-23) where VAT category code (ibt-118) is "Zero rated" the VAT category taxable amount (ibt-116) MUST equal the sum of Invoice line net amount (ibt-131) minus the sum of Document level allowance amounts (ibt-92) plus the sum of Document level charge amounts (ibt-99) where the VAT category codes (ibt-151, ibt-95, ibt-102) are "Zero rated".
What the rule checks
As the rule set's publisher wrote it. The rule runs on every element the context matches, and fails where the test is false; the validator reports the line of that element.
