Why Amazon (Vendor Central) code ASN-ACC deductions happen
EDI 856 ASN did not match the receipt at Amazon FC — wrong carton count, wrong UPC, wrong unit count per carton, or wrong PO reference. In practice, this is rarely a single root cause. Amazon (Vendor Central)'s receiving and audit systems flag asn accuracy chargeback the moment a discrepancy hits the threshold — so even a clean shipment can take a deduction if the paperwork or the EDI handshake doesn't reconcile cleanly on the retailer's side. That's why almost every code ASN-ACC packet hinges on documentation timing, not on whether the shipment was actually correct.
