SAP C4C & S/4HANA Integration with Apache Camel
Seamless bidirectional integration between SAP Cloud for Customer (C4C) and SAP S/4HANA using Apache Camel — synchronising accounts, opportunities, and order confirmations across the CRM and ERP systems in near real-time.
Project Overview
The Challenge
The client ran C4C for sales and S/4HANA for finance and fulfilment as completely separate systems. Sales reps had no visibility into stock or credit limits. Finance had no view of pipeline. Data was reconciled manually in weekly exports, causing billing delays and lost deals.
Our Solution
We implemented an Apache Camel integration layer deployed on Apache Karaf. SOAP/OData adapters connect to both systems. Camel routes handle account master sync, opportunity-to-quote flow, and order confirmation callbacks. A dead-letter channel with retry logic ensures zero data loss on transient failures. All messages are logged to a central audit store.
The Results
End-to-end lead-to-cash cycle cut from 5 days to same-day. Zero manual reconciliation for account and order data. Sales team gained real-time stock and pricing visibility inside C4C. Finance reporting accuracy improved to 99.8%. System processes ~2,000 messages/day with 99.95% uptime.
