Introduction
SAP Business Technology Platform (BTP) offers powerful tools through the SAP Integration Suite to design, deploy, and manage integration flows. However, as systems grow, so does the complexity of integrations. This blog explores how pallets and adapters can be leveraged to build scalable, modular, and maintainable integration flows in SAP BTP.
Why Scalability Matters in Integration Design
Scalable integration flows are essential for:
Handling increasing data volumes. Supporting multiple systems and protocols. Reducing maintenance overhead. Improving performance and reliability.
What Are Pallets?
Pallets are reusable integration components that encapsulate common logic. Think of them as building blocks that can be reused across multiple integration flows.
Logging Pallet
Purpose: Captures and stores transaction details for auditing and debugging.
Contents:
Content Modifier: Extracts headers and payload metadata. Script Step (Groovy): Formats log message. Write to Data Store or external logging system. Transformation Pallet
Purpose: Applies business rules and transforms data formats. Contents:
Message Mapping: Converts data formats (e.g., JSON to XML).
Script Step (Groovy): Applies custom business logic. Content Modifier: Adds or modifies fields. Error Handling Pallet
Purpose: Manages exceptions and ensures graceful failure handling. Contents:
Exception Subprocess: Captures errors. Script Step: Extracts error details. Email or Webhook Adapter: Sends alerts. Logging Step: Records error context. Notification Pallet
Purpose: Sends alerts or notifications based on business events. Contents:
Content Modifier: Prepares notification message. Mail Adapter or Webhook Adapter: Sends notification.
Router: Determines notification conditions. Security Pallet
Purpose: Applies security checks or token validation. Contents:
Script Step: Validates JWT or API keys. Content Modifier: Extracts security headers. Router: Enforces access control.
You can create a pallet as a separate integration flow and invoke it using the Process Direct adapter, enabling loose coupling and reusability.
What Are Adapters?
Adapters are connectors that enable communication between SAP Integration Suite and external systems. They abstract the complexity of protocols and data formats, allowing developers to focus on business logic.
REST Adapter
Purpose: Communicates with RESTful APIs.
Features: Supports GET, POST, PUT, DELETE; handles JSON/XML; supports OAuth2, Basic Auth.
SOAP Adapter
Purpose: Communicates with legacy SOAP-based web services.
Features: Supports WSDL; handles XML/SOAP envelopes; supports WS-Security.
OData Adapter
Purpose: Interacts with SAP systems like S/4HANA using OData protocol.
Features: Supports CRUD operations; handles JSON/XML; supports OAuth2/SAML.
IDoc Adapter
Purpose: Sends or receives IDocs from SAP ERP systems.
Features: Supports ALE/EDI; handles structured IDoc formats; requires SAP connectivity.
JDBC Adapter
Purpose: Connects to relational databases.
Features: Executes SQL queries; supports Oracle, SQL Server, HANA; requires JDBC driver.
ProcessDirect Adapter
Purpose: Enables internal communication between integration flows.
Features: Lightweight; no network overhead; ideal for calling pallets.
SFTP Adapter
Purpose: Transfers files over secure FTP.
Features: Supports file polling, reading, writing; handles encryption and authentication.
Each adapter supports configuration options for authentication, headers, payload formats, and error handling.
Conclusion
Designing scalable integration flows in SAP BTP is not just about connecting systems — it’s about building a robust, future-proof architecture. By leveraging pallets and adapters, you can create modular, maintainable, and high-performing integration solutions that grow with your business.
