This video is an introduction to the new ways of thinking and the related concepts of OO (Object Oriented) ABAP.

An example of encapsulating data using a function group is presented, and the advantage of using OO ABAP instead of procedural programming is demonstrated.

Introduction

Based on your existing knowledge of procedural programming with ABAP, I will explain the object-oriented approach using a Function Group.
I will illustrate one of the advantages of using object-oriented programming over procedural programming.
Let’s start by encapsulating data - a concept of the object-oriented programming mode – using a function group in ABAP.

Encapsulating Data: Speed

Function Group with functions to control the speed of a car.

FUNCTION-POOL zfg_vehicle.

*speed is a global variable

*used in the function-pool

DATA: speed TYPE i.

FUNCTION zfm_increase_speed.
ADD i_speed TO speed.

ENDFUNCTION.

FUNCTION zfm_decrease_speed.
SUBTRACT i_speed FROM speed.

ENDFUNCTION.

FUNCTION zfm_get_speed.
e_speed = speed.

ENDFUNCTION.
