What it means
The rule warns when the payment terms block (cac:PaymentTerms) of the invoice or credit note holds a cac:SettlementPeriod. In UBL this is a period during which the payment terms apply, such as the days in which an early payment discount can be taken. EN 16931 carries payment terms only as text (BT-20). Some rule sets apply this rule to the same UBL element in the same way. This is a warning.
Why it matters
EN 16931 does not use cac:SettlementPeriod in cac:PaymentTerms.
How to fix it
Write the terms in words in the payment terms text (BT-20), for example the discount percentage and the number of days it is available. Then delete cac:SettlementPeriod from cac:PaymentTerms in the XML. If your invoicing software has a separate field for early payment terms, copy its content into the payment terms text and leave the period empty. Check the corrected file again.
