Warning

UBL-CR-516: A line should not have its own VAT point date

In short

Warning: worth checking.

UBL-CR-516 means an invoice or credit note line contains a tax point date (cbc:TaxPointDate), which EN 16931 does not use at line level. It is a warning. Remove the date from the line; if a VAT point date applies to the whole document, use the document-level field.

What it means

The rule checks every cac:InvoiceLine in a UBL invoice and every cac:CreditNoteLine in a UBL credit note for cbc:TaxPointDate. It does not check the document-level VAT point date (BT-7).

Why it matters

EN 16931 provides a VAT point date (BT-7) for the whole document rather than a separate date on each line.

How to fix it

Delete cbc:TaxPointDate from cac:InvoiceLine or cac:CreditNoteLine. If a VAT point date applies to the whole invoice or credit note, put it in cbc:TaxPointDate directly under the document root (BT-7). Do not simply move different line dates into that single field. Recheck the file.
