What it means
In UBL the specification identifier (BT-24) is cbc:CustomizationID. For the Dutch NLCIUS it must start with urn:cen.eu:en16931:2017#compliant#urn:fdc:nen.nl:nlcius:v1.0. The rule only checks the beginning, so text after it does not cause this rule to fail. Leading and trailing whitespace is removed and internal runs of whitespace are collapsed to one space before comparison. This rule checks cbc:CustomizationID elements that are present; it does not check that the element exists.
Why it matters
This code tells the recipient which rule set the invoice is intended to follow.
How to fix it
Choose the output format NLCIUS or SI-UBL 2.0 in your invoicing software and export again. If you build the XML yourself, set cbc:CustomizationID to the identifier above. If the invoice is not meant for the Dutch NLCIUS, check it against the rule set of its own format instead.
