CII-DT-071: Leave the description out of the invoicing period

In short

Fatal: fails the selected checks.

CII-DT-071 means the invoicing period contains a free-text Description element, which is not allowed. Fix it by removing the text from the period and putting any wording in an invoice note instead.

What it means

The invoicing period (BG-14), or the period on a line (BG-26), sits in BillingSpecifiedPeriod and may hold only a start date and an end date. This rule checks that there is no Description element, a free text that describes the period.

Why it matters

EN 16931 describes a period by its dates alone, so a file with a text description inside the period does not meet the standard. It fails and is rejected.

How to fix it

Delete the Description element from BillingSpecifiedPeriod. If the wording matters, such as 'Monthly support', put it in an invoice note (BT-22) or in a note on the line it belongs to (BT-127). Make sure the start and end dates are filled in, as they now carry the period.

The rule as published

Description shall not be used.
