Create global class in sap abap

Attributes are internal data objects of any ABAP data type within a class. The content of the attributes specifies the state of the object. Reference variables can also be defined, which can then be used to create and address objects. This allows objects to be accessed within classes.

2 Flavors of SAP ABAP Classes:

Classes in ABAP Objects can be declared either globally or locally. You define global classes and interfaces in the Class Builder (Transaction SE24) in the ABAP Workbench . They are stored centrally in class pools in the class library in the Repository. All ABAP programs have access to these global classes.
