SAP OO ABAP Objects with Real Time Examples and OOALV

• Global class can be created in se24
• Can be created in se80 which is object browser

• To use the attributes and methods of the class we need an object.
• class is just a template
• object is instance of the class

object in a class can be called as

• reference of the class
• instance of the class
• object of the class

Methods are where we manipulate the data inside attributes.

Import and Export parameters are used to transfer data from one object to other

we will use MARA table which is material master in this example

and the fields MTNR which is material number

• MARA-MTNR = material number
• MARA-MTART = material type description
• MARA-MEINS = unit of measure

Because we don't have any option to create table types in se24

We create them in se11 and add them where required in class builder

static attributes and static methods can be called in programs using the class name instead of creating object.

• static attributes are called as class attributes
• static methods are called as class methods

Always remember that when we create Events there should be a Event handler method

Constructors are special kind of methods, they are called as soon as the object is created,

Constructors are used to initialize the default values

Class constructor is nothing but it is static.

Interfaces only contains method declaration, It contains only methods names and parameters.

Implementation is done in class which adds this interface

Instead of writing the methods when creating class, We can inherit all the properties of the class through inheritance

Local class is only for that program and in that program
