What it means
The invoicing period start date (BT-73), when present, must be a valid date with a year from 2000 to 2099. In UBL invoices and credit notes, this is cac:InvoicePeriod/cbc:StartDate at document level, not within an individual line.
Why it matters
The start date tells your buyer when the period covered by the document begins. It needs to be a valid date within the year range allowed by this rule.
How to fix it
Find the document-level billing or service period and check its start date, including the year, month and day. Correct it against the period you are billing for. If your software copies it from a contract or subscription record, check that source too. Export the corrected file and check it again.
