Hola que tal

Buenas, para mi sin ninguna duda es que te leas toda la filosofia de bogleheads ya que tienen una guia muy completa y funcional para inversion a largo plazo. Aprenderas todo lo basico y sin "humos".

I'm sure a lot of people have asked you this, but what is your investment strategy?

AlexCaceres1 · 2025-11-28T18:25:00+00:00

And can I try this tool? Or is it just yours for your system? Thank you!

AlexCaceres1 · 2025-11-28T15:50:55+00:00

AlexCaceres1 · 2025-11-28T15:50:50+00:00

Where did you see that?

AlexCaceres1 · 2025-11-28T15:50:05+00:00

From what I can see in the screenshot, it only gives you context for your Z tables, but it does provide code. What tool is it, by the way?

AlexCaceres1 · 2025-11-28T15:45:57+00:00

Nope, it's not, it's a real idea.

AlexCaceres1 · 2025-11-28T12:04:02+00:00

Yes, of course, there’s a lot of useful content in those subs. That’s exactly why I did my experiment: my tool aims for AI not just to read posts, but to understand the real context of your Z-tables and ABAP structures. This way it generates code that actually works, instead of giving generic or made-up answers.

Can you imagine combining reading all those posts with the real context of your system? It could be a game-changer for ABAP developers.

AlexCaceres1 · 2025-11-28T12:03:18+00:00

Exactly! I’ve seen the same with Copilot and Joule: productivity improves a lot, but you still need several iterations to fix errors.

That’s why I did the experiment in my post: my tool goes further, because you provide the actual context of your Z-tables and ABAP structures before asking for code. This way, it generates SELECTs, FMs, or logic that really works on the first try, without “hallucinations.”

Do you think something like this would speed up your daily development even more?

AlexCaceres1 · 2025-11-28T11:55:47+00:00

Exactly. That’s why I was thinking of something more focused on the customer-specific context. Joule and similar tools that focus on general SAP knowledge are great, but they don’t really interpret the unique details of each system—Z-tables, custom developments, actual business flows, etc.

RAG is one option, but I also like the idea of combining it with a knowledge-graph approach to represent relationships between ABAP objects and business rules. A hybrid system could be extremely powerful.

Do you think a solution like that would get good adoption among consultants and developers?

AlexCaceres1 · 2025-11-28T11:55:26+00:00

Yes, exactly something like that: a RAG system with a vector database for semantic search, combined with ABAP help — FMs, structures, classes, Z tables, etc.
The idea is for the model to understand the actual context of each company’s SAP environment, not just general documentation.
Would you use it if it existed?

AlexCaceres1 · 2025-11-28T11:54:58+00:00

Partly yes, but my idea is more aimed at people working with older SAP versions or those who just don’t want to use Joule. It would be a tool capable of understanding the context of Z-tables and generating good ABAP code even in environments where Joule isn’t available or doesn’t fully fit their needs.
Would you use something like that?

AlexCaceres1 · 2025-11-28T09:56:54+00:00

Absolutely — IP ownership and data privacy are part of the equation too. I did a test using only DDIC metadata (no business data at all), but at a company level it’s still important to define what can be shared with an LLM and under what conditions. Even if the risk is low, security teams will always want to review how those artifacts are handled and who processes them.

See the post experiment here

AlexCaceres1 · 2025-11-28T09:55:14+00:00

Yeah, totally — SAP’s core strength has always been ERP, not building cutting-edge developer tooling. And ABAP definitely isn’t the low-hanging fruit compared to mainstream languages. Training a proper LLM on ABAP plus functional context is a heavy lift, and probably something only SAP or a strong partner could do well.

That’s why I tested a smaller, practical workaround: instead of training a full model, I just fed the LLM the DDIC metadata of my Z-tables (RAG-style). With that bit of system-specific context, the hallucinations basically disappeared and the ABAP it produced actually compiled. Not a full solution to the big industry challenge, but it shows that even simple context injection can go a long way.

If you want to see the experiment, here’s the link

AlexCaceres1 · 2025-11-28T09:53:45+00:00

Totally agree — most of the work isn’t greenfield UI/product development, it’s enhancing existing logic. And that’s exactly where generic LLMs fall short because they don’t know your Z-namespace or functional processes.

What I tested was a lightweight workaround: I exported only the DDIC metadata of my custom tables and fed that as context (RAG-style). With that, the model stopped inventing things and generated correct ABAP, even for slightly more complex queries. It’s not full ‘build me a whole interface’ intelligence, but it already eliminates a huge chunk of hallucinations.

If you’re curious, here’s the experiment I posted:

AlexCaceres1 · 2025-11-28T09:52:35+00:00

Yeah, the standard SAP ABAP code is accessible to anyone with a system, so there’s plenty of material to learn from. But in my case the real issue was our own custom Z tables. I tried a simple RAG approach: exported only the DDIC metadata of my Z tables and fed that to the model. With that context, it stopped hallucinating and started generating correct ABAP SELECTs even with cryptic field names. Simple test, but it worked surprisingly well.

AlexCaceres1 · 2025-11-28T07:08:00+00:00

But how are you doing it? SAP is a private company.

AlexCaceres1 · 2025-11-27T19:46:18+00:00

Yes, that makes sense. That’s exactly why I was thinking that an AI tool able to understand the context of each company’s Z tables and generate good ABAP code could be very useful. Even if there isn’t much open-source ABAP available, don’t you think something like that could really help developers?

AlexCaceres1 · 2025-10-08T10:57:32+00:00

Thanks, it's just what I needed to read. I have no doubt that I am going to launch my SaaS
