For DDS with the status external (created outside Polygon One), fields such as country, submitted on, supplier country, and plot data may be empty — only the reference number and verification number are captured.
From the DDS detail view, you can submit a DDS in draft status to TRACES directly. The “Verify status in TRACES” feature is currently in preparation and not yet available.
For customs clearance, both the DDS reference number and the verification number are required. Both are included in the export file and the PDF version.
