In today’s interconnected enterprise landscape, seamless integration between legacy SAP Business Suite systems and modern cloud applications is critical for business agility. The SAP Integration Suite serves as a cloud-based integration platform that bridges on-premise SAP Business Suite systems with various SAP and non-SAP cloud services, enabling real-time data exchange and process orchestration.
This article provides a comprehensive guide on setting up SAP Integration Suite to connect with SAP Business Suite, ensuring smooth, secure, and scalable integration.
¶ Understanding SAP Business Suite and SAP Integration Suite
-
SAP Business Suite: A set of integrated business applications running on-premise, including SAP ERP, CRM, SCM, and others. These systems form the backbone of many enterprises but are traditionally siloed.
-
SAP Integration Suite: A cloud-based Integration Platform as a Service (iPaaS) offering capabilities for application, data, and process integration across hybrid landscapes.
Integrating SAP Business Suite with SAP Integration Suite enables organizations to leverage cloud innovation without disrupting their core business processes.
- Acts as a secure tunnel between on-premise SAP Business Suite and SAP Integration Suite.
- Enables secure, firewall-friendly communication.
- Ensures that only authorized traffic flows between cloud and on-premise systems.
- Cloud environment where integration artifacts (iFlows) are designed, deployed, and managed.
- Provides adapters and tools to connect with SAP Business Suite using protocols like IDoc, RFC, SOAP, and OData.
- The on-premise backend system to be integrated.
- Must have appropriate components installed and configured to support integration (e.g., SAP Gateway for OData, SAP PI/PO if applicable).
- Ensure SAP Business Suite system is patched and running on supported versions.
- Activate necessary services like OData or SOAP web services.
- Configure users and roles for secure communication.
- Enable and configure RFC destinations if remote function calls are part of the integration.
- Install SAP Cloud Connector on-premise in the same network as SAP Business Suite.
- Connect Cloud Connector to the SAP Integration Suite tenant using tenant URL and credentials.
- Define backend systems (SAP Business Suite) in Cloud Connector with accessible hostnames and ports.
- Set access control policies to permit traffic only from SAP Integration Suite to required services.
- Access SAP BTP cockpit and create or use an existing Integration Suite service instance.
- Assign necessary roles and authorizations to developers and administrators.
- Configure destinations within SAP Integration Suite to point to SAP Business Suite backend through the Cloud Connector.
- Use the Cloud Integration design tool to create iFlows connecting SAP Business Suite to target systems.
- Select appropriate adapters (e.g., IDoc, RFC, SOAP, OData).
- Configure mappings, routing, and error handling.
¶ Step 5: Deploy and Test
- Deploy the iFlows to the Integration Suite tenant.
- Perform connectivity tests and data validation.
- Monitor message processing via the Integration Suite monitoring dashboard.
- Security: Use HTTPS, certificates, and OAuth for secure communication.
- Monitoring: Enable alerting and logging to promptly detect and resolve issues.
- Scalability: Design iFlows with modular components for reusability.
- Documentation: Maintain clear documentation of system connections and configurations.
- Version Control: Use transport management to track changes in integration artifacts.
- Hybrid Landscape Support: Combine on-premise stability with cloud agility.
- Faster Innovation: Leverage cloud services without disrupting core systems.
- Reduced Complexity: Centralize integration logic on a scalable platform.
- Improved Visibility: Real-time monitoring and analytics for integration processes.
- Enhanced Security: Controlled and secure data exchange across environments.
Setting up SAP Integration Suite with SAP Business Suite is a strategic move that allows organizations to modernize their IT landscapes while protecting existing investments. With secure connectivity via SAP Cloud Connector and flexible integration capabilities, businesses can achieve seamless hybrid integration, unlock new digital opportunities, and drive operational excellence.
