ABAP FS 🚀

A VS Code extension that gives AI assistants real, live access to your SAP system — reads actual code, queries live tables, runs tests, debugs, and understands your custom objects.

Ask "How does BAPI_USER_GET_DETAIL work?" and the AI finds the function, reads the code, checks where it's used, and examines related objects — without you opening anything manually.

• 40 specialized AI tools giving Copilot deep SAP awareness
• Works with GitHub Copilot, Cursor, Claude Code, Windsurf and more (via MCP)
• Full development workflow: code, debug, test, ATC, transports, dumps — all in VS Code

🎯 What Makes This Different?

Context Awareness: Connects directly to your SAP system. When you ask for help, it searches your actual system, reads real function signatures, queries actual tables, and understands your custom objects. The AI doesn't guess—it knows.

Autonomous Investigation: The AI explores your codebase independently. Ask "How does BAPI_USER_GET_DETAIL work?" and it finds the function, reads the code, checks where it's used, examines related objects—without you opening anything manually.

Integrated Workflow: Everything in one place—code, SAP GUI execution, debugging, ATC findings, runtime dumps, performance traces, transport management—without switching between tools. The AI can help with all of it because it has access to all of it.

Natural Interaction: Instead of memorizing commands or navigating menus, ask questions in plain language. "Where is this BAPI used?" "Show me all Z classes with 'pricing' in the name." "Run ATC and explain the findings." The AI uses the right tools automatically.

Built for Reality: Features like automatic fallbacks for older SAP systems, optional whitelist-based access control, and telemetry reflect real-world development needs.

📖 Documentation

For comprehensive documentation covering all features in detail, see the Documentation Site. It's generated by the sources in the docs folder To see it locally run npm run docs and open a browser on the resulting url To enable this you need python and uv

🚀 Installation

Prerequisites

• VS Code 1.90.0 or higher
• SAP system with ADT (ABAP Development Tools) enabled
• GitHub Copilot subscription (for AI features)

Note: Unless your SAP system is relatively modern (NetWeaver 7.51 or later), write support will require you to install abapfs_extensions plugin in your development server. Browsing and reading work without it.

Installation Steps (Will need to follow slightly different steps for custom builds)

1. Install from VS Code Marketplace — Ctrl+Shift+X → search "ABAP remote filesystem" → Install
2. Configure connections — Ctrl+Shift+P → ABAP FS: Connection Manager → add your SAP systems
3. Connect — Ctrl+Shift+P → ABAP FS: Connect to an SAP system
4. Follow the walkthrough — appears on first install, or Ctrl+Shift+P → Get Started: Open Walkthrough → search "ABAP"

For detailed setup, see the Installation Guide. For AI subagents configuration, see the Subagents Guide.

📚 How It Works

ABAP FS provides two interaction modes:

The AI tools are invoked automatically by Copilot — you just ask questions in natural language. Commands are for manual operations like connecting to a system, running a transaction, or activating code.

See the full documentation for details on all tools and commands.

For organizations wanting to deploy ABAP FS internally with access control, telemetry, or custom builds, see the full Organization Administration Guide.

Covers:

• SAP System Whitelist (restrict which systems users can connect to)
• Azure Application Insights telemetry (optional central analytics)
• Building and distributing custom VSIX packages
• Proxy support

Note: The extension from VS Code Marketplace does NOT send any telemetry to external servers. All usage data is stored locally only.

⚠️ Limitations

• Text Elements - CREATE/UPDATE only works on newer SAP systems with ADT API; older systems fall back to GUI
• Transport Management - May require direct table queries on older systems (automatic fallback)
• Copilot Code Search - Only searches committed code, not unsaved local changes
• Save/Activation - Code changes are saved to SAP only when user manually saves (Ctrl+S, Keep button, etc) or activates(activate button). No more automatic saving to SAP as and when you type.
