SAP Business Application Studio (BAS) is an SAP Business Technology Platform (SAP BTP) service that provides a modern development environment, easily accessible via an internet browser, designed for developing SAP solutions.
Business Application Studio (BAS)
The foundation of Business Application Studio (BAS) is the open-source Visual Studio Code (VS Code), developed by Microsoft and adopted by a wide community of developers. SAP took the flexible and powerful infrastructure of VS Code and built BAS by adding specific extensions, tools, and integrations that facilitate application development on the SAP BTP platform. This allows developers to work in the modern and user-friendly interface they are familiar with from VS Code, while also benefiting from SAP-specific capabilities optimized for scenarios like Fiori, CAP (Cloud Application Programming Model), and SAP HANA development. When Dev Spaces are created, SAP extensions suitable for the selected development type are automatically installed and configured, enabling developers to start developing directly without wasting time on environment setup.
The core working principle of BAS relies on Dev Spaces. A Dev Space is a project-specific, cloud- running, and completely isolated environment. Each Dev Space comes pre-packaged with the appropriate tools and runtimes for the selected development type (e.g., Fiori, CAP, S/4HANA extension). Technically, each Dev Space consists of containers running within a Kubernetes Pod, containing the necessary development components.
