You use the source code-based mode of the Class Builder to edit the complete source of global classes in a single editor window. The complete source includes public, protected, private and package sections and method implementations excluding local class definitions, implementations and macros.
The Source Code-Based Class Builder is integrated with the ABAP Workbench and is started by default if you have selected it as the default editor. For more information, see Settings of the Class Builder .
Source Code-Based Class Builder
This mode of the Class Builder is available only for standard ABAP classes and interfaces. Exception classes, global test classes or persistence classes are currently not supported.
