GNC EDI Requirements

The ASN (Advance Shipping Notice) contains detailed information about the products that are being sent to GNC and as well as transportation information. For example, the numeric gross weight, SCAC code, carrier name, tracking number, date, mandatory carrier assignee, lot number, serial number and expiration date will be included in addition to data that comes from the purchase order.

GNC uses the SOPI format for ASN’s. SOPI stands for Shipment, Order, Pack (carton) and Item. SOPI is also known as “Pick and Pack” because more than one type of item can be packed into the same carton. GNC uses two types of SOPI ASN’s which are:

Small parcel shipments

Truck and non-small carrier shipments
