Hi

Business System

1) Business system is a logical system, and there is an importance on physical existence of the system.

2) Also SLD entry is required.

3)It is generally used for SAP applications, this is just a general prinicple followed but not mandatory.

4)This is defined as part of the SLD and is a physical system whose parameters are well defined.

5(Business systems refers to the physical systems, for instance the R/3 system. You define the business systems in the SLD

Business Service

1) You use a Business Service, when you do not have the System details of the the partner system to which you want to communicate. i.e. you have not configured the partner system in SLD.

2) Business Service is an Absract Unit with Sender and Receiver Interfaces,In this case you need to explicitly add the message interfaces while doing configuration in ID.

3) It is generally used for NON-SAP applications, this is just a general prinicple followed but not mandatory.

4) This is not defined as part of SLD and whose technical parameters are not completely known.

5)Business service is used when the message is not addressed to a business system. It is used mostly in B2B scenarios.

A Business System is something that physically exists.

Let us assume, you want to download a file from a mainframe, transfer this file with file adapter and put it in an R/3 with an RFC call.

Then the mainframe and the R/3 are your business systems, which do physically exist.

You use Business Service, when the message is not addressed to a Business System in your system landscape. It is used mostly used in B2B scenario, where you don't know the Business Systems of your partner.

When we talk about Business System, we are talking about those system which have been defined in the System Landscape Directory, For all our A2A Scenario we generally define Business System.

When we talk about Business Services, we are talking about individual services, that services could be one of the service of our Business System also. For all our B2B Scenario we genrally prefer using Business Services. It helps us in communicating with our business partner, without exposing our (Business) Landscape.
