  • Integration Flows
  • Adapters
  • Message Transformation and Mapping
  • Process Orchestration
  • Monitoring and Reporting

How does SAP CPI differ from SAP PI/PO?

  • Answer: SAP CPI is cloud-based, has lower infrastructure requirements, and supports agile integration. SAP PI/PO is on-premise and more suitable for complex, large-scale enterprise systems.

What is an Integration Flow (iFlow) in CPI?

  • Answer: An iFlow is a graphical design of an integration scenario in SAP CPI, enabling data flow between sender and receiver systems.

  • Answer: Common adapters include:
  • HTTP
  • SOAP
  • OData
  • FTP/SFTP
  • Mail
  • IDoc

Explain the role of Content Modifier in CPI?

  • Answer: The Content Modifier is used to modify or add message headers, properties, and payload during integration.

What is a Groovy Script in SAP CPI?

  • Answer: Groovy scripts are used for advanced data manipulation and custom logic that cannot be achieved through standard mapping.

What is a Message Mapping in CPI?

  • Data Store Select: Retrieve saved messages based on a condition.

How is error handling managed in SAP CPI?

  • Answer: Error handling is implemented using Exception
  • Subprocesses, Alerts, and Logging mechanisms.

What is an Externalized Parameter in CPI?

  • Answer: Externalized Parameters are used to define values that can be configured outside the iFlow, making it reusable and environment-independent.

Explain the use of Value Mapping in CPI?

  • Answer: Value Mapping translates values from one set to another, often used in scenarios with differing terminologies or formats between systems.

Scenario-Based Questions

How do you connect SAP CPI with a third-party system?

  • Answer: Use the appropriate adapters (e.g., HTTP, SOAP, or OData), configure endpoint URLs, authentication, and certificates if needed.

How would you monitor integration flows in SAP CPI?

  • Answer: Use the CPI Web UI’s Monitoring tab to track message processing, view logs, and manage alerts.

Describe a scenario where you used SAP CPI for a complex integration.

  • Answer: Example: “I integrated SAP SuccessFactors with a third-party payroll system using SOAP adapter, data transformation, and exception handling.”

What steps would you take to optimize an iFlow in CPI?

  • Answer: Steps include minimizing Groovy scripts, optimizing mappings, avoiding redundant steps, and using asynchronous processing when possible.

How do you implement API Management in SAP CPI?

  • Answer: Use the API Management component to expose, secure, and monitor APIs, while enabling policy-based control for authentication, throttling, and analytics.
