If you receive a late ASN chargeback, it's worth reviewing the full transaction trail: when the 856 was created, when it was transmitted, when Walmart received it, and whether an acknowledgment or other receipt confirmation was returned. Those timestamps help determine whether the issue was a timing problem, a transmission issue, or a mismatch in the shipment details.
Walmart’s requirements vary by program and routing guide, so the most reliable resource is the current guidance tied to your specific supplier agreement.
