Creating ABAP Classes

Context

You can create local or global ABAP classes to build a template for objects.

Note The following procedure is for all development objects that you can create completely using the Eclipse-based wizards. ABAP interfaces and executable programs are created in a similar manner.

Procedure

In the Project Explorer, select the relevant package node.
Open the context menu and choose New ABAP Class to launch the creation wizard.
Specify the Project and Package properties of the ABAP class to be created.
Enter the Name and Description for the class to be created and choose Next.
Note Use [Your Prefix]CL_[Your Class Name] as the name.
Enter the name of the Superclass in case the new class has to be inherited from a specific superclass.
Tip When editing the superclass, you can avail of the content assistant functionality by pressing Ctrl + Space.
Assign a transport request.
- Select the Choose from requests in which I am involved radio button to pick an already existing transport request.
- Select the Create a new request radio button in order to generate a new transport request. In the Request description field, type further information.
- Select the Enter a request number in order to add your class to an existing request. Choose the Browse... button if you want to select a request that has already been created by a certain user.
Start the creation with Finish.

Results

The back-end system creates an inactive version of a class pool in the selected package that is stored in the class library of the repository. In the Project Explorer, the new class is added to the Source Library of the corresponding package node. In the source code editor, the initially generated source code is displayed and ready for editing.

After you have created an ABAP class, the following tabs are available in the class editor:

Tab	Description
Global Class	Class that is stored in the class library of the central ABAP Repository
Class-Relevant Local Types	Contains local definitions that are referenced in the private section of the global class Note When these local definitions are changed, all subclasses and friends of the global class must be recompiled because they might depend on these definitions.
Local Types	Contains local definitions that are NOT referenced by the global class
Test Classes	Contains ABAP Unit test classes that enable automated tests during the development phase
Macros	Allows you to add macro definitions for the given global class Caution Macros are regarded as obsolete technology and should no longer be used in ABAP classes.
