What it means
The invoice contains an invoicing period (BG-14) but neither its start date (BT-73) nor its end date (BT-74) is filled in.
Why it matters
An empty period tells the recipient nothing about when the goods or services were supplied, which they may need for VAT.
How to fix it
Enter the start date, the end date or both for the period the invoice covers, or remove the empty period if it does not apply.
The rule as published
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. Business terms: BG-14, BT-73, BT-74
