Automotive OEMs and suppliers manage hundreds of thousands of part numbers across global plants. Without centralized governance, material duplicates accumulate—industry studies indicate that 18-25% of automotive parts catalogs contain redundant entries, inflating inventory costs and complicating just-in-time delivery.
Tier 1 suppliers connect to multiple OEMs, each with unique vendor codes and requirements. When vendor data is fragmented across systems, EDI transmissions fail, call-offs become inaccurate, and supplier scorecards lose credibility. Inconsistent payment terms create cash flow disputes.
OEMs, dealers, fleet operators, and aftermarket distributors each require distinct pricing, delivery, and billing configurations. Inconsistent customer hierarchies lead to incorrect pricing, missed rebates, and invoice disputes that strain critical commercial relationships.
Automotive enterprises operate 50-200+ interfaces connecting ERP, MES, PLM, supplier portals, and OEM systems. A single field mismatch—wrong unit of measure, missing plant assignment, or outdated vendor code—can cascade through the entire interface chain, halting production across multiple sites.
A Tier 1 supplier received inaccurate EDI call-offs from an OEM because the vendor master in the OEM's system had an outdated delivery schedule. The supplier built up inventory based on incorrect forecasts, while the OEM's actual demand was 40% lower.
An automotive component manufacturer's interface to a customer portal failed silently for 72 hours. The material master lacked a required plant assignment for the new production site, so all delivery confirmations were rejected by the OEM's system.
An interface transmitted purchase orders using 'EA' (each) while the supplier's system expected 'PC' (piece). For months, order quantities appeared correct but the receiving system interpreted them incorrectly, causing systematic over-delivery.
After an ERP upgrade, vendor codes were reformatted from 6 to 10 digits. Legacy interfaces continued sending old formats. Purchase orders, delivery schedules, and invoices couldn't be matched—suppliers weren't paid for weeks.
We document every interface touchpoint, identifying which master data objects flow between systems and where synchronization gaps create failure risks.
Establish golden records for materials, vendors, and customers with consistent field standards, units of measure, and code formats across all connected systems.
Implement SAP MDG workflows with automotive-specific validation rules—ensuring new materials have required plant assignments, vendor records include EDI configurations, and customer hierarchies support complex pricing.
Design master data change processes that automatically validate impact on downstream interfaces before activation, preventing silent failures.
Deploy real-time data quality dashboards tracking master data completeness, consistency across systems, and interface health metrics.
