Description

Introduction

Object-Oriented Programming (OOP) in ABAP brings modern programming paradigms to SAP development, allowing developers to create modular, reusable, and maintainable applications.
OOP in ABAP is built on fundamental concepts like classes, objects, inheritance, polymorphism, encapsulation, and interfaces. It provides a robust framework for designing scalable enterprise applications and is the foundation of modern SAP technologies such as ABAP Objects, ALV OO, Web Dynpro, and SAP S/4HANA development.
This training is designed to help participants transition from procedural ABAP to object-oriented development with hands-on examples and best practices.

Prerequisites

Participants should have:

• Basic knowledge of procedural ABAP programming

• Familiarity with data types, internal tables, and Open SQL

• Understanding of modularization techniques (subroutines and function modules)

• Logical and analytical problem-solving skills

The Object-Oriented Programming (OOPs) in ABAP training provides participants with a deep understanding of modern ABAP development principles.
By mastering OOP concepts such as encapsulation, inheritance, polymorphism, and interfaces, learners can develop structured, reusable, and scalable SAP applications.
This course builds a strong foundation for advanced ABAP frameworks and technologies like Web Dynpro ABAP, BOPF (Business Object Processing Framework), and S/4HANA ABAP RESTful Programming Model (RAP).
