Moving to SAP S/4HANA does not automatically eliminate ABAP performance problems. Explore 10 practical anti-patterns involving SQL, internal tables, CDS views, and database access, along with optimization techniques and performance analysis using ST0...
VA05 in S/4HANA has its own BAdIs for custom columns. I read what the code does with them in S/4HANA 2020 and 2023: only visible columns are read, a column with a standard name is dropped, and two active implementations make both stop running without...
Building agents, CI pipelines or tools on the ADT REST API? Most of my bugs were places where the API answers 200, "finished" or an empty list, and something else happened. Eight traps, measured in an S/4HANA 2023 system, with the reason behind each ...
A local AI model keeps the client's code on your machine and has no token bill. I measured what that looks like on a normal developer PC: speed, how much of the ABAP compiles and passes hidden tests on S/4HANA 2023 and 2020, and four things to check ...
A CDS view with joins, a consumer that reads one field. I measured on 7.55 and 7.58 which joins HANA drops, which one it never drops, and what happens to your row count when the declared cardinality is wrong.
In one of my SRM sourcing developments I needed to move RFx responses (bids) to a new status from custom code: accept a bid in one case, reject it in another. The business status of a response is not a field you can simply update. It lives in the gen...
OData POST Returning 403 "CSRF Token Validation Failed"? A Practical Checklist: ~CHECK_CSRF_TOKEN, and the Headers People Forget
I recently built a unified approval inbox for SRM documents — one Fiori-style screen where an approver could see everything waiting on them across document types and approve or reject in bulk, instead of opening each document individually. The single...
The ATC findings on database tables are the ones everybody scrolls past. I read the class behind the Table Attributes Check in S/4HANA 2020 and 2023 and ran it on 12 real tables: two of its rules are errors, and "Buffering not allowed" doesn't silenc...
A POST to an ABAP OData V4 service fails with /IWBEP/CM_V4H_RUN/042 "CSRF token is invalid", and the token is right there in the request. I followed the check in the standard code of S/4HANA 2020 and 2023: here is what it really validates, and the co...
You put a WHERE on top of your CDS Table Function. Does HANA filter at the table, or after running your whole SQLScript? I measured four styles of table function on S/4HANA 2023, with execution plans and timings.
I replaced BAPI_PO_CREATE1 with EML on I_PurchaseOrderTP_2 in my S/4HANA 2023 lab. The code was short. The surprises were not.
Most ABAP incident time goes into finding things, not fixing them. I export the whole package as plain text with a small read-only report (ZGCTS_EXPORT), let Claude build a knowledge graph from it, and then debug by asking questions. In my support wo...
As we know, when we change any entry in the ALV grid from CL_GUI_ALV_GRID, event DATA_CHANGED will be triggered, and we can do some custom validation checks there.However, you may have faced this situation, after you change the ALV and push on some u...
Learn how to combine SAP S/4HANA Email Templates, CL_SMTG_EMAIL_API, and CL_BCS to send branded HTML emails with CID-based inline images while keeping the subject and body maintainable outside the ABAP code.

ADT is just a REST API — so a small headless Python script can read ABAP source from a BTP ABAP Environment trial, no Eclipse and no browser login. The catch is the OAuth grant; here's the one that works.
CDS View Migration to CDS View Entity – A Practical Step-by-Step GuideCDS View Entities are the modern evolution of the classic DDIC-based CDS views and provide a simplified, more efficient development model in ABAP. SAP provides migration tools and ...
My honest take on the SAP ABAP Cloud certification's system-based assessment — real hands-on tasks in a live system, not multiple-choice theory. Here's what it's actually like, and a few tips that helped.
IntroductionThere is a specific kind of satisfaction that comes from sitting down at a quiet, fanless desktop machine, opening a single IDE window, and having an AI agent autonomously write, syntax-check, activate, and unit-test ABAP code on a live S...

SAP SRM - Header Status Determination
92% of SAP consultants want to train in AI. Only 13% use SAP's. The gap is not distrust — it is friction. And one of the three frictions is an engineering problem we can actually solve.
Beyond basic CRUD: a practical look at implementing bound actions, unbound functions, and draft-aware business logic in RAP-based OData V4 services — with tested code and the draft-context pitfalls that trip up most implementations.
