In today’s dynamic enterprise landscapes, integration solutions must not only connect systems but also intelligently route messages based on context, content, or business rules. SAP Cloud Platform Integration (CPI), as part of the SAP Integration Suite, offers robust capabilities to implement message routing that supports complex integration scenarios efficiently.
This article introduces the concept of message routing in CPI and explores how to design, implement, and optimize routing logic within your integration flows.
Message routing in CPI refers to the logic that determines how and where an incoming message should be directed within an integration flow. Depending on specific conditions—such as message content, header values, or system parameters—a message may be routed to different receivers, processed in different ways, or even filtered out.
Routing is essential when:
SAP CPI provides several mechanisms for message routing:
Routes messages based on values found in the message body or headers.
Example Use Case:
How to Implement:
Routes messages based on header values, such as message type, sender system, or custom headers.
Example Use Case:
Region = US vs Region = EU.How to Implement:
Determines the target dynamically at runtime, often using scripts or variables.
Example Use Case:
How to Implement:
Sends the same message to multiple branches simultaneously for parallel processing.
Example Use Case:
How to Implement:
Scenario: You want to route incoming purchase orders based on the country of the buyer.
Start with a Sender adapter (e.g., HTTP or SFTP).
Use a Content Modifier to extract the Country field from the message payload and store it in a header.
Add a Router step:
Define conditions like:
/Order/Country = 'US'
/Order/Country = 'DE'
Connect each route to a different receiver or further processing logic.
Add End Message or Receiver Adapter to complete each branch.
Implementing message routing in SAP Cloud Platform Integration is a critical skill for building flexible and scalable integration scenarios. Whether it’s routing by content, headers, or dynamic logic, CPI provides a rich set of tools to ensure that each message reaches the right destination based on business context. By understanding the routing types and best practices, integration developers can design efficient flows that meet both technical and business requirements.
