How to fix DTDC "COD is not allowed for DOX Shipments" error?
This error appears when you try to book a COD shipment through DTDC while the document type is set to DOX (Document).
Why this happens: DTDC doesn't allow Cash on Delivery on Document-type shipments. COD is only permitted for Non-Document (packages).
How to fix:
- Open ILS → Logistics Configuration → DTDC → Edit.

- Change Document type to Non-Document.
- Click Save and retry the shipment.
