How to fix BR-TMP-6
Datumsangaben in UBL müssen im Format JJJJ-MM-TT (YYYY-MM-DD) übermittelt werden.
XRechnung rule from the KoSIT XRechnung 3.0 schematron (German CIUS of EN 16931). It applies only to invoices whose specification identifier (BT-24) is XRechnung. Such files are checked against EN 16931 and the KoSIT XRechnung rules instead of the full Peppol BIS rule set. Check your file with the XRechnung validator.
What this rule checks
UBL only. Dates must be written as YYYY-MM-DD without time or time zone. The rule checks cbc:IssueDate, cbc:DueDate, cbc:StartDate, cbc:EndDate, cbc:ActualDeliveryDate, cbc:TaxPointDate and cbc:PaymentDueDate.
How to fix it
Write all dates as plain YYYY-MM-DD, e.g. 2026-10-15. Remove time parts and offsets such as T00:00:00 or +02:00.
