In the evolving landscape of SAP development, integrating various SAP BTP services smoothly is crucial for delivering end-to-end business solutions. One such powerful integration is between SAP Business Application Studio (BAS) and the SAP Integration Suite. This integration empowers developers to build, deploy, and manage integration flows, APIs, and extensions all within a modern, cloud-based development environment.
This article provides an overview of how to integrate BAS with SAP Integration Suite, highlighting best practices and typical use cases in the SAP ecosystem.
¶ Overview: SAP Business Application Studio and SAP Integration Suite
SAP Business Application Studio is a comprehensive cloud-based IDE tailored for SAP development. It supports multiple SAP technologies, including SAP Fiori, SAP Cloud Application Programming Model (CAP), and SAP Integration Suite development. BAS offers a developer-friendly environment with pre-configured Dev Spaces, rich editing, and built-in deployment tools.
SAP Integration Suite is SAP’s cloud-based integration platform as a service (iPaaS). It provides capabilities to connect SAP and non-SAP systems through:
- Integration Flows (iFlows)
- API Management
- Event Mesh (messaging)
- Open Connectors
- Process Integration and Orchestration
Together, BAS and SAP Integration Suite offer an integrated experience for developing both applications and integration artifacts.
- Unified Development Experience: Develop and test integration flows and APIs alongside application logic without switching tools.
- Streamlined DevOps: Automate deployment and version control through BAS integrated Git and CI/CD pipelines.
- Faster Time-to-Market: Rapidly prototype integrations with local testing and cloud deployment.
- Extensibility: Combine SAP UI5/Fiori apps or CAP services with Integration Suite’s powerful connectivity.
To start integrating BAS with SAP Integration Suite, ensure the following:
- Access to an SAP BTP subaccount with SAP Integration Suite enabled.
- SAP Business Application Studio workspace configured.
- Assigned user roles such as
IntegrationDeveloper and DevOps.
- Connectivity setup between BAS and Integration Suite via destination service or service keys.
- Open BAS and create a new Dev Space with the Integration Suite or Full Stack Cloud Application template. This template comes preloaded with tools for developing integration artifacts.
To interact with Integration Suite services:
- Create a Destination in SAP BTP Cockpit pointing to your SAP Integration Suite tenant.
- Configure authentication (OAuth2, Basic Auth, or API Key) in the destination.
- In BAS, bind the destination to your project environment to consume Integration Suite APIs securely.
You can develop integration content in BAS in various ways:
- Integration Flow (iFlow) Development: Use the Integration Suite web UI alongside BAS by linking them or manage deployment artifacts exported from BAS.
- API Management: Design APIs in BAS using OpenAPI specifications and deploy them to SAP Integration Suite.
- Event-Driven Development: Write functions or extensions in BAS that publish or subscribe to events on SAP Event Mesh within Integration Suite.
¶ Step 4: Test and Deploy from BAS
- Use local emulators and mock data to test integration flows or APIs.
- Deploy integration artifacts programmatically using CI/CD pipelines configured in BAS.
- Monitor deployments and runtime logs through BAS integrated terminals or SAP Integration Suite dashboards.
Imagine you are developing a CAP-based application in BAS that requires data synchronization with an on-premise ERP system.
- Build your CAP service and expose OData APIs.
- Develop an integration flow in SAP Integration Suite to connect to the on-premise system via Cloud Connector.
- Use BAS to orchestrate the integration flow deployment, manage API definitions, and write custom logic for event handling.
- This integrated approach accelerates development and ensures seamless communication between cloud and on-premise.
- Version Control: Use Git repositories integrated with BAS for all integration artifacts.
- Use Destinations: Manage endpoints securely and centrally in SAP BTP destinations.
- Automate Deployments: Implement CI/CD pipelines in BAS to automate delivery to SAP Integration Suite.
- Leverage Extensions: Use SAP Business Application Studio extensions to simplify Integration Suite development workflows.
Integrating SAP Business Application Studio with SAP Integration Suite streamlines the development lifecycle of modern SAP applications and integrations. This synergy enables developers to build robust, scalable, and secure business solutions leveraging SAP’s cloud-native technologies.
By adopting this integrated development approach, organizations can accelerate innovation, reduce complexity, and improve collaboration across development and integration teams.
