Goods line has no classification
Enter a valid digits-only HS code on the item or configure the permitted default.

Enter the item GTIN and review the VAT Posting Setup reverse-charge classification.

Confirm the status-polling Job Queue entry is running. Then use manual Refresh Status.
Received document cannot match a vendor
Confirm:
- The supplier TIN is present.
- Exactly one vendor has that TIN.
- The vendor is not duplicated.
- The document parsed successfully.
Document cannot be resubmitted
Refresh the status first. TCA must explicitly report whether resubmission is allowed.
Registration outcome unknown
Do not send again immediately. Check the TCA portal and reconcile the TCA document identifier to avoid duplicate filing.
