11. Explain Groovy Scripting in SAP CPI.
A: Groovy Scripting is used within an iFlow to perform complex message transformations and custom logic that cannot be achieved through graphical modelling.
12. What is MPL (Message Processing Log) in SAP CPI?
A: MPL is a log that tracks a message's progress and state throughout its lifecycle within CPI, helping with troubleshooting and performance analysis.
13. What is the difference between Message Mapping and XSLT Mapping?
A: Message Mapping is graphical and maps data from source to target.
XSLT Mapping uses XML Stylesheets and is typically used to transform XML data using XSL rules.
14. How do you handle errors in SAP CPI?
A: Error handling in SAP CPI can be managed using:
Exception Subprocesses: To handle specific errors within an iFlow.
Alerting: To notify responsible personnel.
Retry Mechanisms: Automatically retry failed message transmissions.
15. What is the difference between synchronous and asynchronous integration in SAP CPI?
A:
16. How do you secure messages in SAP CPI?

17. What is the use of Splitters in SAP CPI?
A: Splitters are used to split a single message into multiple smaller messages for parallel processing or further transformation.
18. How does SAP CPI integrate with SAP SuccessFactors?
A: SAP CPI provides pre-built integration content for connecting with SuccessFactors using specific adapters, such as the SuccessFactors OData Adapter, for seamless data exchange.
19. What is Message Persistence in SAP CPI?
A: Message Persistence refers to storing message data to ensure its availability in case of system failure or for reprocessing purposes.
20. What is Data Transformation in SAP CPI?
A: Data Transformation involves converting data from one format or structure to another as it passes between different systems during integration.
21. Explain the role of the Router in SAP CPI.
A: The Router is used for message routing based on conditions. It helps direct the message flow to different branches of an iFlow depending on predefined conditions.
22. What are the best practices for designing iFlows in SAP CPI?
A: Best practices include:
23. What is API Management in SAP Integration Suite?
A: SAP API Management, part of the SAP Business Technology Platform, allows you to manage, secure, and monitor APIs across the enterprise, ensuring smooth API-based integrations.
24. How does SAP CPI ensure GDPR compliance?
A: SAP CPI ensures GDPR compliance by providing data encryption, secure processing mechanisms, and access control to protect sensitive data.
25. What is the role of the ProcessDirect Adapter in SAP CPI?
A: The ProcessDirect Adapter is used for synchronous and asynchronous message exchange between different flows within the same CPI tenant.
26. How do you enable Trace for an iFlow in SAP CPI?
A: Tracing in SAP CPI can be enabled within the iFlow by setting the Log Level to Trace in the integration flow properties. This allows detailed logging of message payloads, headers, and properties during runtime.
27. What is an Integration Package in SAP CPI?
A: An Integration Package is a collection of multiple iFlows, message mappings, and other artifacts grouped together to manage and deploy integration scenarios.
28. How does the OData Adapter work in SAP CPI?
A: The OData Adapter in SAP CPI integrates with services using the OData protocol. It allows data to be sent and received from OData-compliant systems by performing operations like GET, POST, PUT, and DELETE.
29. What are Persisted Messages in SAP CPI?
A: Persisted messages are stored on disk space of CPI rather than in memory. This ensures that message data is not lost in case of a system restart or failure, providing reliability in processing.
30. Explain the concept of Message Versioning in SAP CPI.
A: Message Versioning in SAP Cloud Platform Integration (CPI) is a feature that allows you to manage different versions of your integration flows. This is particularly useful when you need to make updates or changes to an existing integration flow without disrupting the current operations.
31. What are Value Mappings in SAP CPI?
A: Value Mappings map different representations of the same data across systems, ensuring consistency in data transformation. For example, mapping currency codes between systems that use other standards.
32. What is the difference between SOAP and REST in SAP CPI?
A:
33. What is the use of Externalized Parameters in SAP CPI?
A: Externalized parameters allow you to change the configuration of an iFlow without modifying the underlying code. These parameters can be set outside the iFlow, enhancing flexibility during deployment.
34. What are Message Properties in SAP CPI?
A: Message properties in SAP CPI are metadata that accompany messages as they flow through the integration process. These properties are often used for routing, filtering, or custom processing logic.
35. How does SAP CPI handle Data Privacy?
A: SAP CPI provides robust features like encryption, secure communication channels, and access control to safeguard data privacy and ensure compliance with regulations like GDPR.
36. What are Integration Artifacts in SAP CPI?
A: Integration artifacts are individual components that constitute an integration scenario. These include iFlows, message mappings, scripts, adapters, and more.
37. Explain the Exception Subprocess in SAP CPI.
A: An Exception Subprocess is a mechanism to handle errors within an iFlow. It defines specific actions to be taken when an error occurs during message processing, such as sending alerts or retrying operations.
38. What is the Timer Process in SAP CPI?
A: The Timer Process is a start event in an iFlow that triggers the integration flow based on a scheduled time. It is useful for periodic tasks such as syncing data between systems.
39. What is the Local Integration Process in SAP CPI?
A: A Local Integration Process is a subprocess within an iFlow that can encapsulate a set of processing steps. It helps in reusing logic within the same iFlow, promoting modularity and code reuse.
40. What are the differences between a Polling and an Event-Driven Process in SAP CPI?
A:
A: Security certificates in CPI are configured in the Keystore. These certificates ensure secure communication channels, like HTTPS and FTPS, and enable digital message signing.
42. Explain the concept of Retry Mechanism in SAP CPI.
A: The CPI retry Mechanism automatically retries failed message processing steps, either due to temporary network issues or other system errors, ensuring the reliability of message delivery.
