BR-CO-19 and BR-CO-20: a period needs a start date or an end date

The same conditional check at two levels. If a period group is used at all, at least one of its two dates must be filled, and both may be. BR-CO-19 covers the document level Invoicing period (BG-14) and BR-CO-20 covers the Invoice line period (BG-26). An empty period group is the failure case. Omitting the group entirely is not.

BR-CO-19

If Invoicing period (BG-14) is used, the Invoicing period start date (BT-73) or the Invoicing period end date (BT-74) shall be filled, or both.

About the BR-CO family

Calculation and consistency rules. These check that the totals on the invoice add up and agree with the line items and VAT breakdown.

Related rules

A validator reports one code at a time. These check the same fields, so they are the ones most likely to fire on the same invoice.

  • BR-29 If both Invoicing period start date (BT-73) and Invoicing period end date (BT-74) are given then the Invoicing period end date (BT-74) shall be later or equal to the Invoicing period start date (BT-73).
  • BR-30 If both Invoice line period start date (BT-134) and Invoice line period end date (BT-135) are given then the Invoice line period end date (BT-135) shall be later or equal to the Invoice line period start date (BT-134).
