SAP Cloud Platform Integration (SAP CPI) is a robust, cloud-based middleware platform that facilitates integration between SAP and non-SAP applications in a hybrid environment. While SAP CPI provides out-of-the-box connectivity and basic message processing, mastering advanced integration patterns empowers architects and developers to build scalable, resilient, and maintainable integration solutions.
This article explores some of the most important advanced integration patterns supported in SAP CPI, enhancing enterprise integration scenarios.
Integration patterns are reusable solutions for common challenges in connecting disparate systems, managing data flow, and ensuring message reliability and consistency. They originate from the famous book “Enterprise Integration Patterns” by Gregor Hohpe and Bobby Woolf.
In SAP CPI, understanding and implementing these patterns help design flexible and efficient iFlows (integration flows) that align with business requirements.
Definition: Routes messages to different target systems or processes based on message content or attributes.
In SAP CPI:
Benefits:
Definition:
In SAP CPI:
Use Case: Processing bulk orders where each order line is processed individually but results are combined before final delivery.
Definition: Sends a request to multiple recipients in parallel (scatter) and waits for all responses to aggregate them (gather).
In SAP CPI:
Use Case: Query multiple backend systems simultaneously and combine results for consolidated reporting.
Definition: Enhances a message with additional data retrieved from an external system.
In SAP CPI:
Example: Add customer credit rating information from a credit bureau service during order processing.
Definition: Filters out unwanted messages based on criteria, preventing unnecessary downstream processing.
In SAP CPI:
Definition: Multiple consumers process messages concurrently from the same queue to improve throughput.
In SAP CPI:
Definition: Messages that cannot be processed are sent to a special queue or channel for later analysis.

Mastering advanced integration patterns in SAP CPI elevates the quality and robustness of enterprise integrations. These patterns provide standardized solutions to complex challenges in routing, transformation, error handling, and scalability. By leveraging these design patterns, SAP CPI developers can create efficient, reliable, and adaptable integration landscapes aligned with evolving business goals.
For SAP architects and developers, continuous learning and practical application of these patterns are essential to unlock the full potential of SAP CPI.
