Rule-based SAP monitoring misses what AI catches. This practical guide walks through algorithm selection, ABAP feature extraction, and integration architecture for real anomaly detection.
Need a single HTTP entry point for your ABAP backend but no API Management license? Here's how to build a lightweight REST gateway directly in ABAP using ICF handlers and a table-driven router.
Building an ABAP OData V4 service with RAP is more structured than old SEGW work — once you understand CDS layers, behavior definitions, and the transactional buffer, you move fast.
RFC, OData, REST, IDoc — four SAP integration protocols, four different trade-offs. Here's a practical decision matrix built from real S/4HANA projects to help you pick the right one.
Working code and fast code are not the same thing. These 10 ABAP performance mistakes appear constantly in new developments and silently destroy scalability when real data volumes hit.
Still using FOR ALL ENTRIES out of habit? In 2026, HANA JOINs and tuple subqueries are measurably faster for most scenarios. Here's the benchmark data and when FAE still wins.
12 practical ABAP SQL optimization patterns for HANA that senior developers actually use in production — from eliminating SELECT-in-loops to window functions and proper aggregation pushdown.
ST05, SAT and SQLM are the three tools every ABAP developer needs for performance tuning. Learn how to use each one, when to switch between them, and how to act on what they tell you.
Forget hunting through SAP docs. This CDS annotations cheatsheet covers 30 annotations grouped by purpose — analytics, OData, Fiori UI, and access control — with real syntax and honest usage notes.
CDS Fiori Elements annotations control everything — from filter bars to Object Page sections. Here's the practical guide with real code for List Report and Object Page layouts.
The same 10 CDS views performance antipatterns show up on nearly every S/4HANA project. Here's what they look like in code — and how to fix them before they reach production.
DCL and CDS roles let you enforce row-level security at the data layer — filtering what users see before your application code ever runs. Here's how to do it right.
Testability isn't something you bolt onto ABAP code later — it's built in through upfront architectural decisions. Here's exactly what those decisions look like in practice.
Facing a 3,000-line procedural ABAP report? This step-by-step walkthrough shows you how to extract data, logic, and presentation into clean OOP classes without breaking production.
No framework needed. Constructor, setter, and factory injection patterns that make your ABAP classes testable and decoupled — with practical code examples you can use today.
Five principles, real ABAP code. Learn how SOLID applies to production SAP systems — with concrete before/after examples for every principle from SRP to DIP.
Tired of nested IF blocks managing SAP approvals? The ABAP chain of responsibility pattern combined with State and Iterator gives you a workflow engine that actually scales.
LLMs can hallucinate vendor numbers, fabricate amounts, and invent material keys — all with complete confidence. Here's how to build the validation layers that keep them out of your SAP production system.
