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.
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.
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.
