General Motors EDI integration for automotive suppliers

A guide for suppliers connecting with General Motors, covering schedules, ship notices, error feedback and ERP integration.

Overview

Understanding General Motors integration

Who this is for: Production and service parts suppliers to General Motors plants and facilities, and the EDI teams that support them.

General Motors exchanges planning and shipping information with its suppliers electronically. Suppliers typically receive planning schedules with forecast and authorization data and shipping schedules with firm near-term requirements. They respond with advance ship notices for each shipment. General Motors can return application advice documents that report problems found in submitted documents, which gives suppliers a feedback loop for correcting errors.

As with other vehicle manufacturers, document accuracy has operational consequences. Ship notices must match physical shipments and container labels, and schedule updates need to reach production planning quickly. Suppliers serving plants in several countries may also work with different standards or versions.

General Motors provides supplier information through its supplier portal. Third-party sources note that the precise documents depend on the supplier's commodity, geography and supply model, so suppliers should confirm their requirements with General Motors directly.
