Series note: This post is part of my AI ABAP development series, where I go from AI development in general, to ABAP-specific problems, and then to ARC-1. In the first post of this series, I wrote more generally about how I use AI today, why context matters so much, and why I am still not fully convinced by the more maximalist agentic hype. Here I want to get more concrete. Because SAP development is not one thing, and that matters a lot for AI. ...

Series note: This post is part of my AI ABAP development series, where I go from AI development in general, to ABAP-specific problems, and then to ARC-1. When it comes to AI, I do not really think about magic. I think more about another colleague helping me out. Sometimes that means architecture. Sometimes implementation. Sometimes testing, review, CI/CD, or deployment. But this only works with trust, and trust needs communication. If I do not know something, I ask. If code looks strange, I ask. If tests fail, I ask. ...

If you work with SAP Fiori Elements, you have probably run into this problem before: it is hard to see in which UI5 version a specific feature was introduced. Bjorn Schulz already built a strong matrix for ABAP: ABAP Feature Matrix. For Fiori Elements and RAP/CAP, there was no comparable matrix yet. So I created an Influence request to close this gap: influence.sap.com/sap/ino/#idea/351729 The new Developer Portal would be a great home for a matrix like this but so far, there still is no official version. The closest alternative is the SAP Fiori Elements Feature Map in the SAPUI5 documentation. ...

If you are searching for SAP MCP Servers (Model Context Protocol), you quickly run into the same problem: Which SAP MCP servers exist (official and community), and what other SAP AI tooling should you know about? That is why I like this new repo: marianfoo/sap-ai-mcp-servers: SAP MCP Servers and SAP AI Skills list It is a curated list of SAP MCP servers, SAP AI skills, and adjacent developer tools. The README is structured as tables so you can scan by category, compare licenses, and see what is actively maintained. ...

Previous post (code generation benchmark): Benchmarking LLMs for ABAP Live benchmark results (old + new): abap-llm-benchmark.marianzeis.de In my first evaluation (based on the TH Köln benchmark paper), I extended the original setup with additional models and focused on a very concrete question: how well can LLMs generate ABAP code that actually compiles and passes ABAP Unit tests? I also tested SAP’s model ABAP-1, and it performed very poorly for code generation. To be fair: SAP also states this in the documentation. ABAP-1 is primarily meant for explaining ABAP code not for reliably generating full working implementations. ...

There is currently a huge hype around the new MCP (Model Context Protocol) servers. I’ve built one for SAP Docs, and there are excellent community projects like the ADT API MCP Server. These tools are fantastic for individual developers. You install them, connect them to your IDE or a local LLM, and suddenly your AI assistant knows about SAP. Architecture overview (in one picture) Before diving into the details, here is the high-level architecture I’m aiming for: ...

Live benchmark results: abap-llm-benchmark.marianzeis.de In a lot of SAP webcasts and webinars, especially around AI, the question comes up very early: which model are you using, and which one do you recommend? For CAP and UI5 the answer is usually pretty simple: use the current best model from Anthropic. If you add good context via MCP servers from the community or SAP, you are basically fine. There is just a lot of public knowledge available, and most of it is in JavaScript/TypeScript, which LLMs handle extremely well. ...

Finally, there is an MCP server for ABAP. You can use it directly in Eclipse via https://mcp-abap.marianzeis.de/mcp. Setup instructions are here: Eclipse configuration (GitHub Copilot) Why a community ABAP MCP server? SAP has announced an MCP server for ABAP, so why create a community one? The trigger for me was the release of Agent Mode in GitHub Copilot for ADT, which finally makes it possible to edit ABAP code by Copilot. LLM models are already really good, but ABAP knowledge is still a recurring problem. So I wanted an MCP server that is actually tailored for ABAP. ...

This post is a mirrored copy of my LinkedIn article, kept here so it remains searchable and independent from external platforms. You can still find the original on LinkedIn: LinkedIn Pulse article. Joule for Consultants costs 250 € and mainly searches SAP Help, SAP Community and SAP for Me (Notes). That is useful, but it stops where real projects start: your own systems, codebase and sensitive data. Even though public assistants like ChatGPT and Claude can already reach SAP Help and SAP Community, the real gap is internal/authenticated data and code. ...

This post is a mirrored copy of my LinkedIn article, kept here so it remains searchable and independent from external platforms. You can still find the original on LinkedIn: LinkedIn Pulse article. Back in April 2024 I opened this little series with From Open Exchange to Corporate Monologue, followed in August by SAP Community in Decline and, just before Christmas, the GPT-assisted look at question quality. Twelve months, two platform releases and several batch-downloads later it is time for round four - this time with a split focus: ...
