BR-CO-19: Invoicing period (BG-14) without start and end date

What does this mean?

If the invoicing period (BG-14) is used, its start date (BT-73) or end date (BT-74) shall be filled, or both. The period in the invoice has neither. In UBL the value added tax point date code (BT-8) in cac:InvoicePeriod is sufficient as an alternative.

Typical causes

The period element was created empty, e.g. because the generating system always writes it.
The dates are stated elsewhere, e.g. only in a note.

How to fix the error

State the start date (BT-73) and/or end date (BT-74) of the period, or omit the period entirely if there is none.
CII: ram:ApplicableHeaderTradeSettlement/ram:BillingSpecifiedPeriod with ram:StartDateTime or ram:EndDateTime, UBL: cac:InvoicePeriod with cbc:StartDate or cbc:EndDate.
Generate and validate the invoice again.

In E-Rechnungsfreund

In the invoice form, expert view ("Experte"), section "Datum & Zeiträume" (dates and periods), fill in the fields "Abrechnungszeitraum Start (BT-73)" and/or "Abrechnungszeitraum Ende (BT-74)" (billing period start/end). If both are empty, no period is written to the XML. Then validate the invoice again.
