Lowe's Code DT: Shortage or Special Order Sales (SOS) shortage deduction (Tracking Code DT / AD, DN, DMH).
Lowe's Tracking Code DT (appearing in Vendor Inquiry with Deduction # prefixes AD + 6 digits for standard Shortage, DN + 6 digits for Auto-Shortage, or DMH + 5 digits / DM + 6 digits for Special Order Sales [SOS] Shortage) means Lowe's recorded receiving fewer units at a Regional Distribution Center (RDC), Flatbed DC (FDC), or store than billed on your invoice. In Lowe's Vendor Inquiry, disputing a deduction is called submitting a 'Chargeback' response.
Why Lowe's issues Code DT.
- Lowe's RDC or cross-dock facility missed scanning cartons during unload
- Part of the shipment was separated at a Lowe's cross-dock (VPXD) or arrived on a second trailer
- Special Order Sales (SOS) shipment was delivered to a store, but the store delayed posting the receipt
- EDI 810 invoice quantity exceeded actual shipped cases
Documents that win.
- Signed Proof of Delivery (POD) for Prepaid shipments or signed Proof of Pickup (POPU) / BOL for Collect shipments
- Advance Ship Notice (EDI 856) and packing list
- Original Purchase Order and Vendor Invoice (select 'Display QTY - POD Attached' or 'VPXD (CROSSDOCK) - POD/POPU/ASN Attached' in Vendor Inquiry)
