Lowe's Code PRC: Cost difference / auto-cost difference deduction (Tracking Code PRC / AD, DN).
Lowe's Tracking Code PRC (paired with Deduction # prefix AD + 6 digits for standard Cost Difference or DN + 6 digits for Auto-Cost Difference) means the unit price on your EDI 810 invoice exceeded the unit cost on Lowe's Purchase Order. To win a dispute in Vendor Inquiry, select 'Display PRC - Price Sheet Attached' or 'Price Sheet and POD/POPU Attached' and upload proof of the approved cost.
Why Lowe's issues Code PRC.
- Approved cost increase was not updated on open POs in LoweLink before the order shipped
- Case-pack vs. each unit-of-measure pricing discrepancy on the invoice
- Temporary promotional cost reduction was applied to a non-promotional PO
Documents that win.
- Approved Lowe's price sheet / cost-change confirmation showing the effective date
- Original Purchase Order and Vendor Invoice
- Signed POD/POPU proving the ship date fell within the approved price effective window
