What it means
The invoice does not state a date of supply through any of the three allowed fields: actual delivery date (BT-72), invoicing period (BG-14), or a per-line invoice line period (BG-26).
How to fix it
Add BT-72 (actual delivery date), or an invoicing period, or per-line invoice line periods -- whichever your source system has available.
