ABAP Programming Foundations

From Syntax to Algorithms in 3 days

Introduction

Why this course

Master core ABAP programming concepts through hands-on exercises and structured problem-solving.

This course focuses on building solid ABAP programming fundamentals through progressive, hands-on exercises. You'll start with basic syntax and data types, then advance through data structures, algorithms, and modern ABAP programming patterns.

Each concept is reinforced through practical coding exercises that mirror real-world programming challenges. By the final day, you'll have mastered the core programming skills that form the foundation of professional ABAP development, with a portfolio of solved problems demonstrating your capabilities.
