General Motors EDI Requirements

General Motors does two types of ASNs. Some suppliers send an ANSI 856 ASN and some suppliers send a DESADV ASN. In either case, the ASN (Advance Shipping Notice) will contain comprehensive information about the products that are being sent to General Motors and as well as transportation information. For example, the shipped date. Shipped time, gross weight, shipped quantity, SCAC code, trailer number, PRO number, number of packages, and cumulative quantity shipped will be included in addition to data that comes from the purchase order.

General Motors uses the SI format for ASN’s that follow the ASNSI standard. SI stands for Shipment and Item. The SI packing structure has one ship level which has one item level for each item number in the shipment.  Item quantities specified are the total for the shipment.

GM uses the DESADV for suppliers who follow the EDIFACT standard. The structure of the DESADV is similar to the SI format discussed above and most often has two levels which are the shipment and item level.
