BR-AG-08
For each different value of VAT category rate (BT-119) where the VAT category code (BT-118) is "IPSI", the VAT category taxable amount (BT-116) in a VAT breakdown (BG-23) shall equal the sum of Invoice line net amounts (BT-131) plus the sum of document level charge amounts (BT-99) minus the sum of document level allowance amounts (BT-92) where the VAT category code (BT-151, BT-102, BT-95) is "IPSI" and the VAT rate (BT-152, BT-103, BT-96) equals the VAT category rate (BT-119).
What does this rule mean?
The taxable amount (BT-116) of a breakdown in category M (IPSI, Ceuta and Melilla) does not match the lines, allowances and charges at that rate.
IPSI has several rates and each rate gets its own breakdown, so the sum is per rate (BT-119), not per category.

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
/*/cac:TaxTotal/cac:TaxSubtotal/cac:TaxCategory[normalize-space(cbc:ID) = 'M'][cac:TaxScheme/normalize-space(upper-case(cbc:ID))='VAT']
CII
//rsm:SupplyChainTradeTransaction/ram:ApplicableHeaderTradeSettlement/ram:ApplicableTradeTax[ram:CategoryCode = 'M'][upper-case(ram:TypeCode) = 'VAT']
Technical test
The rule passes when this Schematron expression holds true:
every $rate in ../ram:RateApplicablePercent/xs:decimal(.) satisfies (../ram:BasisAmount = (round(sum(/rsm:CrossIndustryInvoice/rsm:SupplyChainTradeTransaction/ram:IncludedSupplyChainTradeLineItem/ram:SpecifiedLineTradeSettlement[ram:ApplicableTradeTax/ram:CategoryCode = 'M' and ram:ApplicableTradeTax/xs:decimal(ram:RateApplicablePercent) =$rate]/ram:SpecifiedTradeSettlementLineMonetarySummation/xs:decimal(ram:LineTotalAmount)) * 10 * 10) div 100 + round(sum(/rsm:CrossIndustryInvoice/rsm:SupplyChainTradeTransaction/ram:ApplicableHeaderTradeSettlement/ram:SpecifiedTradeAllowanceCharge[ram:ChargeIndicator/udt:Indicator=true() and ram:CategoryTradeTax/ram:CategoryCode='M' and ram:CategoryTradeTax/xs:decimal(ram:RateApplicablePercent)=$rate]/xs:decimal(ram:ActualAmount[1])) * 10 * 10) div 100 - round(sum(/rsm:CrossIndustryInvoice/rsm:SupplyChainTradeTransaction/ram:ApplicableHeaderTradeSettlement/ram:SpecifiedTradeAllowanceCharge[ram:ChargeIndicator/udt:Indicator=false() and ram:CategoryTradeTax/ram:CategoryCode='M' and ram:CategoryTradeTax/xs:decimal(ram:RateApplicablePercent)=$rate]/xs:decimal(ram:ActualAmount[1])) * 10 * 10) div 100))How to fix it
Touches amounts, VAT or IBAN. We never change these automatically — correct them in your source data.
Recompute per rate: the line net amounts (BT-131) at that rate, plus charges (BT-99), less allowances (BT-92).
