Introduction
In ERP consulting, predictable results come from structure, governance, and execution discipline. When a leading automotive supplier approached us, their challenge was clear: align ERP LN configuration with a modern, pull-based supply chain strategy while standardizing EDI communication across multiple plants and suppliers.
Our mission was to redesign their planning and procurement backbone — ensuring that processes, systems, and data spoke the same language.
Context & Challenge
The client operates globally in the automotive manufacturing sector, producing precision mechanical components for Tier-1 suppliers and OEMs. Despite a mature ERP environment, core processes still relied heavily on manual effort and fragmented logic.
Key challenges included:
- Limited use of EDI in procurement and fulfillment
- Inconsistent supply and forecast processes across sites
- High manual effort in shipping, invoicing, and order handling
- Lack of pull-based planning integration in the ERP LN kernel
Without addressing these gaps, efficiency, scalability, and supplier responsiveness were at risk — directly impacting delivery reliability and production flow.
Our Approach & Key Deliverables
Our consultants structured the project around governance, phased execution, and continuous validation. The transformation started with redefining the planning model through value streams and decoupling points — forming the foundation for a hybrid push/pull environment.
Main deliverables and initiatives:
- Pull-based planning logic: ERP kernel enhancement supporting value streams and decoupling zones.
- Transition to purchase schedules: Replacing single POs with scalable release management.
- EDI integration: Multi-party onboarding for internal and external suppliers via ION middleware and Automotive Exchange.
- Forecast framework: Item-level forecast upload and automated Slim4 integration.
- Invoicing logic redesign: Multi-party invoice flow with packaging surcharge automation.
Each deliverable was directly tied to client value: higher visibility, reduced manual work, and improved synchronization between business and system behavior.
Risks, Challenges & Lessons Learned
No ERP transformation comes without complexity. During execution, several critical risks emerged:
Main challenges and mitigations:
- EDI not supporting pull logic → Designed and mapped new EDIFACT message flows for purchase schedules and ASNs.
- Internal vs. external supplier discrepancies → Standardized the process model to unify requirements.
- Forecast integration gaps → Implemented Slim4 upload with item-based planning windows.
- Kernel limitations → Change request initiated early, enabling the kernel redesign phase.
Lessons learned:
- Integrating EDI from the beginning prevents late-phase rework.
- Forecast logic must be decoupled at both process and system level.
- A value-stream approach is critical to maintain flexibility in hybrid supply chains.
The PMO emphasized continuous steering sessions and early validation to ensure transparency and predictable outcomes — proving that governance is as vital as technical expertise.
Results & Impact
The redesigned model provided both measurable and qualitative improvements across the supply chain:
Operational results:
- Automated forecast uploads and schedule releases
- Reduced manual effort in procurement and shipping
- Higher data accuracy and planning transparency
Strategic impact:
- Strengthened supplier collaboration and communication
- Improved responsiveness to customer demand changes
- Established a scalable framework for future EDI rollouts
In short, the project moved the client from fragmented processes to an integrated supply chain where demand, forecast, and system execution are fully aligned.
Conclusion
This initiative reinforced that successful ERP consulting is not about technology alone — it’s about designing clarity, predictability, and trust into every process. For this automotive manufacturer, the shift to pull-based planning and unified EDI logic marks a sustainable step forward toward operational excellence.
As we continue to support their rollout and supplier expansion, the project stands as a testament to the value of structure, governance, and long-term partnership in ERP transformation.
