SAP CPI.

SAP CPI is a cloud middleware platform designed to securely connect distinct systems across an enterprise. It enables seamless data exchange between SAP-to-SAP, SAP-to-Non-SAP, and on-premise-to-cloud architectures. It handles data transformations, message routing, and protocol translations in real time.

• SAP PI/PO (Process Integration / Process Orchestration): A traditional, on-premise middleware tool installed locally on an enterprise server infrastructure. • SAP CPI: A modern, cloud-native iPaaS (Integration Platform as a Service) hosted and fully maintained by SAP. It offers flexible subscription-based scaling and features pre-packaged, out-of-the-box integration content.

SAP CPI supports a wide array of built-in adapters out of the box to communicate with different endpoints. Supported Protocols & Adapters include: • Web Services / APIs: HTTPS, REST (OData), SOAP, RFC • File Transfers: SFTP, FTP, IDoc • Cloud Messaging: AMQP, JMS, Kafka, AS2, AS4, Mail

Security is handled natively through strict multilayer mechanisms managed inside the SAP Business Technology Platform (BTP): • Transport Security: Compulsory HTTPS, TLS encryption, and secure VPN routing via the SAP Cloud Connector. • Authentication: Supports Client Certificate Authentication, OAuth 2.0, Basic Authentication, and SAML assertions. • Message Level: Built-in cryptographic operations to sign, encrypt, decrypt, and verify message payloads.

The Discovery tab inside the SAP Integration Suite (available in the SAP BTP Trial Account) allows you to directly browse, explore, and clone those exact pre-packaged integration packages from the SAP Business Accelerator Hub.

SAP Open Connectors provide a built-in library of over 170+ preconfigured adapters for non-SAP cloud applications. Instead of building custom REST frameworks, developers use Open Connectors to instantly normalise APIs, credentials, and error handling for platforms like HubSpot, ServiceNow, and Amazon S3.

Third-party systems predominantly communicate via modern JSON payloads, while core SAP backends rely heavily on structural XML (IDocs/SOAP). CPI resolves this using built-in transformation blocks: • JSON to XML / XML to JSON Converters: Instantly flips the payload script. • Message Mapping: A graphical drag-and-drop structural map to align fields, supported by custom XSLT or Groovy scripts for high-complexity structural modifications.

Yes. By deploying the JDBC (Java Database Connectivity) Receiver Adapter, CPI can securely write to, update, or read data from standard third-party databases. Supported Non-SAP DBs include: • Microsoft SQL Server (Cloud & On-Premise) • PostgreSQL & MariaDB • Oracle Database & IBM DB2

CPI relies on the SAP Cloud Connector (SCC). The SCC acts as a secure, reverse-proxy agent installed locally within the private on-premise network. It opens a secure TLS tunnel up to SAP BTP, allowing CPI to safely route data to local non-SAP endpoints without the company having to expose public IP addresses or open standard inbound firewall ports.

CPI natively hooks into modern, third-party messaging queues using specialized event adapters. For example, the Kafka Adapter or the AMQP/JMS Adapters can be configured to consume or publish live data streams. This lets CPI act as a real-time message processor interacting with event platforms like Apache Kafka or RabbitMQ.

Groovy scripting is used to implement custom integration logic, manipulate message headers and properties, transform payloads, and handle complex data processing requirements in SAP CPI.

Message Mapping transforms source message structures into target message structures. It helps exchange data between applications with different formats and field requirements.

Synchronous integration waits for a response from the receiving system, whereas asynchronous integration processes messages independently without requiring an immediate response.

SAP Cloud Connector establishes a secure connection between SAP BTP cloud applications and on-premise systems without exposing internal systems directly to the public internet.

Value Mapping converts corresponding values between different systems. For example, it maps a customer status or country code from one application's format to another application's format.

SAP CPI provides monitoring capabilities to track message processing, identify failed integration flows, inspect error details, analyze message logs, and troubleshoot integration issues.

Java Message Service (JMS) is used for asynchronous message processing and temporary message storage. It helps manage message queues and supports reliable integration scenarios.

Partner Directory stores partner-specific configuration parameters, identifiers, and values that can be accessed dynamically during integration processing.

Deployment is the process of activating an Integration Flow so that it can execute in the SAP Cloud Integration runtime. It involves configuring required parameters, deploying the flow, and monitoring its execution.
