PEPPOL-COMMON-R043
Belgian enterprise number MUST be stated in the correct format.
What does this rule mean?
An identifier declared as a Belgian enterprise number does not match the required format.
The scheme identifier promises the value comes from that register, so Peppol checks it: Ten digits with a modulo-97 check (KBO/BCE). If the format is wrong the receiver cannot resolve the party.
Official rule message (standard)
Belgian enterprise number MUST be stated in the correct format.
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
cbc:EndpointID[@schemeID = '0208'] | cac:PartyIdentification/cbc:ID[@schemeID = '0208'] | cbc:CompanyID[@schemeID = '0208']
CII
ram:URIID[@schemeID = '0208'] | ram:ID[@schemeID = '0208'] | ram:GlobalID[@schemeID = '0208']
Technical test
The rule passes when this Schematron expression holds true:
matches(normalize-space(), '^[0-9]{10}$') and u:mod97-0208(normalize-space())How to fix it
