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 Name element, a name given to the period.
Why it matters
EN 16931 describes a period by its dates alone, so a file that gives the period a name does not meet the standard. It fails and is rejected.
How to fix it
Delete the Name element from BillingSpecifiedPeriod. If the name matters to the buyer, such as a billing quarter, put it in an invoice note (BT-22) instead. Make sure the start and end dates are filled in, as they now carry the period.
