Integrating ERP and MES: A High-Level Overview of Digital Infrastructure Architecture

Introduction

ERP integration remains the most requested topic in digital transformation initiatives. However, the traditional approach of using solution stacks as digital infrastructure creates limitations that prevent organizations from achieving true digital maturity. This article explores how unified namespace architecture enables seamless ERP-MES integration while building scalable, event-driven digital infrastructure.

The Fundamental Problem with Traditional Integration Approaches

Solution Stacks vs. Digital Infrastructure

Traditional Vendor Approach: Most vendors (SAP, Rockwell, Schneider, Siemens) advocate using their solution stack as digital infrastructure:

• SAP recommends BTP with PCO, Leonardo, and S4 HANA
• Rockwell promotes FactoryTalk ecosystem
• Siemens suggests their integrated automation suite

The Critical Limitation: Solution stacks are not digital infrastructure. They cannot solve every manufacturing issue in an organization, inevitably requiring integration with "smart things" outside their ecosystem.

The Alternative: Agnostic Digital Infrastructure

Technology-Based Approach:

• Unified namespace architecture
• Open edge-driven, report-by-exception protocols
• Lightweight communication protocols
• Gateway-based legacy system integration
• Functional, informational, and definitional namespaces

Key Benefits:

• Contextualized Data: Semantic hierarchy for data organization
• Normalized Structure: All data points relate to each other
• Machine Learning Ready: Normalized data enables pattern recognition
• Vendor Agnostic: No lock-in to specific solution providers

Real-World Integration Experience

Industry Evidence

Based on 230+ active client implementations, several consistent patterns emerge:

Universal Integration Reality:

• 100% of active projects have some form of ERP integration
• All integrations are custom-built and limited to specific data needs
• Plant floor focus: Successful implementations start on the plant floor and work up
• Operations-driven: Only ERP data that operations cares about is integrated

Key Data Points Typically Integrated:

• Inventory levels and material availability
• Order status and production schedules
• Production and consumption of finished goods
• Product definitions and specifications

Events vs. Transactions: The Fundamental Difference

ERP Systems: Transaction-Based

Transaction Characteristics:

• Multiple events coalesced into single database record
• Single timestamp for entire transaction
• "Near real-time" processing approach
• Designed for business logic and reporting

Example Transaction:

Job Record:
- Job Status: Complete
- Start Time: 08:00
- End Time: 12:00
- Produced Quantity: 150
- Rejected Quantity: 3
- OEE: 87%
- Timestamp: 12:05 (when record was inserted)

Manufacturing Systems: Event-Based

Event Characteristics:

• Single data point change with precise timestamp
• Real-time data capture
• Immediate response capability
• Designed for process control and monitoring

Example Events:

Events:
- 08:00:15 - Job Status Changed: Started
- 10:30:22 - Reject Count Incremented: 1
- 12:00:03 - Job Status Changed: Complete
- 12:00:05 - Final Count Updated: 150

Functional Namespace Creation:

• Reference raw events from multiple sources
• Apply business logic within functions, not in data pipes
• Create reusable, composable business functions

Informational Namespace Assembly:

• Combine functional outputs for specific use cases
• Enable ad-hoc data consumption and analysis
• Support real-time decision-making requirements
