Creating Object Types 
Use
There are two ways of creating a new object type:
- You create a completely new object type
- You create an object type as a
subtype of an existing object type, which inherits the components of the existing object type automatically. For further information, refer to
Creating Subtypes.
Procedure
Choose Tools ®
Business Workflow ®
Development ®
Definition tools ®
Business Object Builder.
This displays the screen Business Object Builder: Initial Screen.
Select 
Create.
The Create Object Type dialog box appears.
Edit the fields Object type, Object name, Name and Description. When doing so, bear in mind the
general naming conventions for object types. Leave the field Supertype blank.
Enter the name of a new program for the implementation of the object type. Bear in mind the naming conventions in your application.
Specify the code letter of your application (usually Y or Z).
Result
You have created a new object type in the
Business Object Repository. The system has put all the entries (ID, object name, name, description) into the basic data of the object type automatically. 
The new object type inherits only the attributes and methods that are in the
standard interface, which is supported by all object types.
