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.
Fetching data to the app server and looping over it in ABAP is the top S/4HANA performance killer. Here are five pushdown patterns that move logic where HANA can actually run it fast.
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.
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.
