Automated batch record integration with ERP for material traceability

I wanted to share our successful implementation of automated electronic batch record integration between Honeywell MES and our SAP ERP system. This project was driven by our quality team’s need for complete material genealogy tracking during compliance audits.

Previously, we were manually reconciling batch records between systems at month-end, which consumed about 40 hours of quality engineer time and created significant risk during audit preparation. With FDA inspections requiring full material traceability from raw material receipt through finished goods shipment, we needed a real-time automated solution.

We implemented an API-based integration using the HM 2023.1 material management API that synchronizes batch record data bidirectionally. The solution captures lot numbers, material consumption, and process parameters from the shop floor and pushes them to SAP in near real-time. This has reduced our audit prep time from 3 days to about 4 hours and gives us complete confidence in our material genealogy data.

I can speak to the audit impact since I work with the integration team. Our most recent FDA inspection was significantly smoother than previous years. The auditors actually complimented our ability to instantly trace any finished goods lot back through all process steps to raw material suppliers.

We demonstrated the genealogy tracking by selecting a random finished product lot and within minutes showed the complete material flow including supplier certificates, receiving inspection results, production batch records, and quality release documentation. Previously this would have taken hours of searching through paper records and spreadsheets. The automated system also eliminated the transcription errors we occasionally had with manual data entry, which gives auditors more confidence in data integrity.

Let me provide a comprehensive overview of how we implemented this solution and the key architectural decisions that made it successful.

Electronic Batch Record (EBR) Architecture: We designed the batch record structure in HM to mirror our paper batch record format, which made regulatory acceptance easier. Each EBR contains sections for material identification, process parameters, quality checkpoints, and operator signatures. The material management module automatically populates lot numbers and quantities as materials are consumed at each process step. This creates a complete digital record that satisfies 21 CFR Part 11 requirements for electronic records.

API-Based Integration Framework: We built the integration using the HM 2023.1 REST API for material management operations. The architecture uses a middleware layer running on our integration server that orchestrates the data flow between HM and SAP. This middleware handles the transformation of HM batch record data into SAP-compatible formats and manages the bidirectional synchronization. We chose REST APIs over direct database integration to maintain system integrity and ensure we’re using supported interfaces that won’t break during upgrades.

Material Genealogy Tracking Implementation: The genealogy tracking captures parent-child relationships at multiple levels. When raw materials are issued to a batch, the system records the supplier lot numbers. As materials move through processing steps, we track transformations including blending, reactions, and packaging operations. Each transformation creates genealogy links showing which input lots contributed to which output lots. This creates a complete traceable chain from raw material receipt through finished goods shipment.

The genealogy data structure includes lot number, material code, quantity, unit of measure, process step, timestamp, and operator ID for every material movement. We also capture equipment IDs and process parameters like temperature and pressure that are critical for batch record completeness. All of this data flows to SAP where it’s stored in custom tables linked to SAP batch records.

Compliance Audit Automation: The real value emerged during our first audit after implementation. We created several pre-built queries that auditors commonly request: forward traceability (where did this raw material lot go?), backward traceability (what raw materials are in this finished goods lot?), and cross-lot analysis (which batches used material from a specific supplier?). These queries execute in seconds by joining the genealogy tables in SAP.

We also implemented automated batch record completeness checks that run nightly. The system verifies that every production batch has all required data elements, flags any missing signatures or quality results, and generates exception reports. This proactive validation means we catch and correct issues immediately rather than discovering gaps during audit prep.

The compliance team now maintains an always-audit-ready state instead of scrambling for weeks before inspections. Our audit preparation time dropped from 3 days to 4 hours because we’re just reviewing the automated reports rather than manually compiling data. The automated genealogy tracking has also enabled faster response to customer quality inquiries and potential recall scenarios - we can now identify affected lots within minutes instead of days.

Did you use standard SAP APIs or custom BAPIs for the ERP integration? We’re evaluating a similar project and trying to determine whether to leverage existing SAP Process Industries interfaces or build custom integration points. Also curious about your error handling strategy when either system is temporarily unavailable.

How has this impacted your actual audit process? You mentioned reducing prep time, but I’m curious about the auditor experience and whether they’ve accepted the automated genealogy tracking without requesting additional manual verification.

We sync several key data elements: raw material lot numbers and quantities consumed per batch, in-process material transformations and yields, quality test results linked to specific lots, and equipment usage records with timestamps. The synchronization happens every 15 minutes during production shifts and hourly during non-production periods.

The critical design decision was making the integration bidirectional - not just pushing data from MES to ERP, but also pulling material master data and lot status updates back from SAP. This ensures both systems maintain consistency and operators see real-time material holds or quality flags from the ERP side.

This is exactly what we need to implement. Can you share more details about how you structured the API integration? Specifically, what data points are you synchronizing and at what frequency? We’re also working toward eliminating manual batch record reconciliation.
