Part 1 –  Core Data Services (CDS) Views

Core Data Services (CDS)  views help you move logic into the database. As a result, this technique, known as code pushdown, is vital for S/4HANA performance.

CDS lets you create fast, reusable data models with clean syntax. Moreover, they’re easy to maintain across multiple use cases.

. For example, you can define a view once and reuse it across reports, APIs, or Fiori apps. We’ll show how to write CDS views and where to use them.

CDS views and AMDP methods aren’t optional—they’re essential tools for performance-driven ABAP.

Part 2 – ABAP Managed Database Procedures (AMDP)

AMDP allows you to write SQLScript directly inside your ABAP classes. When CDS views fall short, AMDP handles more complex or performance-heavy logic.

Part 3 – ABAP RESTful Application Programming Model (RAP)

ABAP RAP  is SAP’s go-to model for building modern enterprise apps. It streamlines development by letting you define business objects, behaviors, and services—all within ABAP.

As a result, you can quickly create OData services that integrate seamlessly with SAP Fiori apps. In this series, we’ll walk through RAP’s structure and explain when to use the managed versus unmanaged implementation styles.

By running operations directly in the HANA database, you reduce data transfer and processing time. Consequently, your code becomes both faster and more efficient.

Part 4 – SAP Fiori and Fiori Elements

Fiori Elements lets you create modern UIs without writing JavaScript. Instead, you define behavior using backend annotations.

This approach saves time and keeps your code clean. You’ll learn how to build a List Report or Object Page using only CDS views.

Part 5 – SAP Business Technology Platform (BTP)

The SAP Business Technology Platform (BTP) is SAP’s cloud platform for extension and innovation. Importantly, it lets you build custom apps without modifying your core S/4HANA system.

By using ABAP in the cloud—often called “Steampunk”—you can develop secure, scalable solutions that integrate tightly with your ERP environment. This approach, therefore, supports flexibility while preserving a clean core.

Part 6 – Extensibility and Enhancement Framework

S/4HANA encourages a “clean core” strategy. That means no more direct code changes.

Instead, you use BAdIs, enhancement points, and key-user tools to customize safely. We’ll explore the right way to extend without creating upgrade problems.

Part 7 – ABAP Development Tools (ADT) in Eclipse

Eclipse-based ADT is now the standard. You need it to work with CDS, AMDP, and RAP. In addition, it offers modern features. These include better debugging tools and Git integration.

Part 8 – New ABAP Syntax

Modern ABAP is shorter and easier to read. You can use inline declarations, table expressions, and new loop styles.

Furthermore, we’ll show before-and-after examples so you can modernize your old code and simplify logic.

What’s Next?

This series will equip you with the skills to build faster, cleaner, and more modern ABAP applications.

Whether you’re modernizing legacy code or starting fresh, each post offers practical insights you can apply right away. In either case, you’ll find tools and examples designed to make your work easier and more effective.
