Business Objects..

[Former Member]

Hi all,

I have a lot of unanswered questions when it comes to business objects (the ones in the business process repository - SWO1).

1. What is the purpose/use of the Business Objects? The also have the same methods and attributes as SE24 classes. But, then why are special?

2. When we add a method to a business object, it asks if we would like to use a function module template.

a) If we choose a BAPI, would that allow us to call that method of business object from another system?

b) If not, is it possible to call a business object method in any other way?

3. I have created instance of business object using SWO_CREATE. I also invoked a method without any parameters using SWO_INVOKE. How can we invoke a method with parameters?

4. Is it possible to create instances of business object from an outside system, for eg. Java? How can it be done?

5. If i call a business object that has a method called CreateMaterial(for eg), will that actually create a new material in the SAP system. I have seen many business objects provided by SAP that seem to do such actions usually done thro transactions.

Thanks in advance.

I would look at this way - Classes are stand alone objects which contain methods, attributes etc. Business Objects can be seen as tied to an Application area such as a MM, SD etc. In other words, they implement a particular business function. You will see that each BO is tied to an application area, whereas a class doesnt need one.

Yes, it is possible to invoke a BAPI from an external system.

Yes it should.

Looks like your other questions regarding creation of objects etc have already been answered in different threads in the forum.
