What is the difference between business object method and a class method?

Hello all,

What is the difference between business object method and a class method? They are both methods but it seems SE80 treats them differently. A method found under the business object heading is not retrievable under the class method heading.

Thank you for your explanation.

Hi,

BO Concept

A business object type is the representation of a business entity, like an employee or a sales order, in an SAP System. It encompasses both the functions (in the form of methods) and the data (in the form of attributes) of this entity. In the process, the implementation details of the business object type are hidden from the end user, and the business object type itself is accessed through defined functions (methods/BAPIs).

Class Concept

Classes are templates for objects. Conversely, you can say that the type of an object is the same as its class. A class is an abstract description of an object. You could say that it is a set of instructions for building an object. The attributes of objects are defined by the components of the class, which describe the state and behavior of objects.

Methods are internal procedures in a class that define the behavior of an object. They can access all of the attributes of a class. This allows them to change the data content of an object. They also have a parameter interface, with which users can supply them with values when calling them, and receive values back from them The private attributes of a class can only be changed by methods in the same class.

Regards,

Renjith Michael.

good

BUSINESS OBJECT METHOD->

The Business Object Repository (BOR) is the object-oriented repository in the R/3 System. It contains the SAP business object types and SAP interface types as well as their components, such as methods, attributes and events.

BAPIs are defined as methods of SAP business object types (or SAP interface types) in the BOR. Thus defined, the BAPIs become standard with full stability guarantees as regards their content and interface.

The BOR has the following functions for SAP business object types and their BAPIs:

Provides an object oriented view of R/3 System data and processes.

R/3 application functions are accessed using methods (BAPIs) of SAP Business Objects. Implementation information is encapsulated; only the interface functionality of the method is visible to the user.

Arranges the various interfaces in accordance with the component hierarchy, enabling functions to be searched and retrieved quickly and simply.

This finds the functionality searched for quickly and simply.

Manages BAPIs in release updates.

BAPI interface enhancements made by adding parameters are recorded in the BOR. Previous interface versions can thus be reconstructed at any time. When a BAPI is created the release version of the new BAPI is recorded in the BOR. The same applies when any interface parameter is created.

The version control of the function module that a BAPI is based on is managed in the Function Builder.

Ensures interface stability.

Any interface changes that are carried out in the BOR, are automatically checked for syntax compatibility against the associated development objects in the ABAP Dictionary.

CLASS METHOD->

This section contains explains how to work with methods in ABAP Objects. For precise details of the relevant ABAP statements, refer to the corresponding keyword documentation in the ABAP Editor. The example shows how to declare, implement, and call methods.

Hi Goharjou

I guess you would also want to know how to use it.

Please refer to Jocelyn Dart's links (Co-autor of the book "Practical Workflows for SAP").

It is a series of helpfuls and similified blogs. The first one is:

http://wiki.scn.sap.com/wiki/pages/viewpage.action?pageId=55566

And the thereafter you can follow the sequence within each.
