Lowe's Code 6NO: 6NO contractual allowance deduction (Tracking Code 6NO / DM######P).
Lowe's Tracking Code 6NO (appearing with Deduction # DM + 6 digits and DM + 6 digits + P in the deduction list) is a contractual Lowe's allowance program deduction. Because Lowe's does not automatically display line-item calculations on allowance deductions in Vendor Inquiry, suppliers must first open a support ticket in LoweLink to request the calculation backup before disputing any overcharge.
Why Lowe's issues Code 6NO.
- Allowance percentage was calculated on gross purchases instead of net purchases
- Allowance was double-deducted (taken both off-invoice and via DM######P)
- Outdated contract rate applied after an agreement renewal
Documents that win.
- Line-item allowance backup obtained via a Lowe's Vendor Gateway support ticket
- Signed Lowe's Vendor Agreement showing exact 6NO allowance terms
- Invoices proving off-invoice discounts if double-deducted
