Purpose

The Class Builder allows you to create and maintain global ABAP classes and interfaces. Both of these object types, like global data types, are defined in the R/3 Repository. Together, they form a central class library and are visible throughout the system. You can display existing classes and interfaces in the class library using the Class Browser.

Note

You can define local classes as well as global classes. They are defined locally in programs, function groups or as auxiliary classes of global classes of the class pools. Local classes are only visible within the defining module.

Integration

The Class Builder allows you to create Web development objects within the ABAP Workbench. You can use the Class Browser to display and maintain existing global object types from the R/3 class library. The diagram below illustrates the architecture of the Class Builder and the relationships between its components (including the Class Browser).

To reach the initial screen of the Class Builder, choose Development à Class Builder from the initial screen of the ABAP Workbench or enter transaction code SE24. From here, you can either display the contents of the R/3 class library or edit a class using the Class Editor. Once you have defined an object type, you can implement its methods. From the initial screen or the Class Editor, you can also access the Class Builder’s test environment. You can define the object types immediately after implementing the method in the ABAP Editor. It is also possible to access the test environment from the initial screen or Class Editor.
