NO-R-001
For Norwegian suppliers, a VAT number MUST be the country code prefix NO followed by a valid Norwegian organization number (nine numbers) followed by the letters MVA.
What does this rule mean?
A Norwegian seller VAT number is not in the form NO<9 digits>MVA.
Norway composes the country code NO, the nine-digit organisation number and the suffix MVA.

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:AccountingSupplierParty/cac:Party[$supplierCountry = 'NO']
CII
ram:SellerTradeParty[$supplierCountry = 'NO']
Technical test
The rule passes when this Schematron expression holds true:
ram:SpecifiedTaxRegistration[ram:ID/@schemeID = 'VAT']/substring(ram:ID, 1, 2)='NO' and matches(ram:SpecifiedTaxRegistration[ram:ID/@schemeID = 'VAT']/substring(ram:ID,3) , '^[0-9]{9}MVA$')
and u:mod11(substring(ram:SpecifiedTaxRegistration[ram:ID/@schemeID = 'VAT']/ram:ID, 3, 9)) or not(ram:SpecifiedTaxRegistration[ram:ID/@schemeID = 'VAT']/substring(ram:ID, 1, 2)='NO')How to fix it
