What is GMC EDI?

GMC EDI is the structured electronic data interchange framework enabling General Motors suppliers to exchange forecast, shipping schedule, ship notice, and invoice information across the automotive supply chain. It enforces OEM-mandated transaction sequencing, shipment data validation, and real-time ERP-to-WMS synchronization to maintain release-based production schedules, strict delivery windows, and trading partner compliance.

GMC EDI Compliance

Where does GMC compliance usually get stuck?

Most compliance issues happen when production schedules and EDI mappings are managed in disconnected workflows.

01

Are your 830 and 862 schedules mapped accurately?

Forecast and shipping schedule mismatches disrupt release-based production planning and can trigger GMC supplier non-compliance penalties.

Fix Gap
02

Does your ASN data match physical shipment labels?

Discrepancies between the 856 ship notice and barcode labels cause receiving delays, rejections, and chargebacks at GM receiving facilities.

Fix Gap
03

Is your invoice validation tied to ship notices?

Untracked variances between the 856 ship notice and 810 invoice delay payments and damage audit readiness.

Fix Gap
The Cogential IT Edge

Why Cogential IT Dominates GMC EDI Compliance

We deliver OEM-grade EDI precision others miss by aligning document logic, label data, and ERP workflows specifically for General Motors requirements.

Release-Schedule Mapping That Holds

We map 830 and 862 schedules directly into your ERP so forecast-to-ship workflows never drift from GMC release requirements.

ASN-Label Packing Slip Alignment

We synchronize the 856 ship notice with barcode labels and packing slips so physical shipments match digital records exactly.

Automotive ERP and WMS Sync

We connect GMC documents to QAD, SAP S/4HANA, Infor, Epicor, D365, SAP EWM, Manhattan, and Kinaxis without brittle middleware.

AS2 Transport Hardened for OEMs

We configure AS2 endpoints with signed receipts, encryption, and retry logic to keep GMC traffic moving without interruption.

Compliance Validation Before Go-Live

We run production-style simulation cycles against GMC rules so your first live transaction passes validation without rework or penalties.

Live Monitoring and Rapid Triage

Our operations team watches transaction queues, flags document failures, and resolves mapping errors before they impact production schedules.

Start Your GMC EDI Deployment

Let our engineers configure the mapping, labels, and AS2 flow while you scale automotive fulfillment.

label and ASN readiness

Keep barcode, carton, ASN, and invoice data aligned.

Barcode labels and packing slips must mirror the 856 ASN so GM can scan, receive, and reconcile every shipment accurately.

01

SSCC Barcode Validation

Confirm each carton label carries a valid, unique SSCC-18 barcode.

02

ASN Data Alignment

Match label quantities, part numbers, and ship dates to the 856 ship notice.

03

Packing Slip Consistency

Ensure printed packing slips reflect the same line details as the electronic ASN.

04

Invoice Reconciliation

Tie the 810 invoice back to ASN and label shipment references.
