SAP BTP Customer Data Integration Architecture unifies customer and account data from Salesforce CRM, SAP S/4HANA Cloud, and non-SAP systems through a centralized integration hub. Data flows via Cloud Integration iFlows, Open Connectors, and Event Mesh into SAP HANA Cloud as a unified data layer, with API Management enforcing policies and rate limiting for secure access. SAP Build Process Automation orchestrates account approval workflows, while SAP Analytics Cloud delivers real-time customer insights dashboards. This architecture demonstrates how to break data silos across heterogeneous systems while maintaining governance, security, and scalability on SAP BTP.

Identity Authentication Service provides SSO and OAuth 2.0 security across all integration touchpoints.
