    Difference between Business Service and Business System are :

    1) Business sytem require all details like login user id

    password require to create but in case of business service

    log in details does not require..

    2) A Business System is purely for SAP-Systems and

    Business Service for Non-SAP systems

    3) Business service refers to any business applications where

    as the business system is defined in SLD(System Landscape


    4) When we have full details of application system the we are

    going to use the business system and it is created in the

    SLD so we dont have authorization to change the business

    system name.

    When we have partial details or no details of Technical

    system then we r going to use the business service. it is

    created in the ID. we can see and change it.

    5) A Business system is something that physically exists

    For example, if u want to download a file from a system

    ABC, by using file adapter and then want to update the

    content of this file into r/3 database by using RFc,then

    the system abc and the r/3 will be ur business systems

    i.e. they physically exists. Business Systems are

    configured in SLD.

    Business service is mostly usedin B2B Scenario (cross-

    component),where you don't know the Business System of your

    partner. In other words business Service will be used only

    for those partners which do not have a physical landscape

    set up . Business servces do not have an entry in SLD.

    6) A Business Service is an Abstract Unit(which is not in

    System Landscape Directory) addressing Senders and

    Receivers of Messages.

    Physicals systems which use their communication channels

    and routing rules to communicate with other systems are

    called as Application Systems OR physical systems.

    7) In simple when u going for A2A integration then we define

    our Technical systems are Business system. If we r going

    for B2B integration then we dont know the complete

    information about the other end Business Landscape so, we

    configure it as a Business Services. Business system are

    created at SLD. Where as a Business Services are created at

    Integration Directory.

    8) Business systems:

    These are logical senders or receivers that exchange

    messages by using the Integration Server and that are

    entered in the System Landscape Directory.

    The business systems in the System Landscape Directory

    relate to a system landscape. The business systems of

    business partners are therefore not entered in the System

    Landscape Directory. To be able to address such business

    partners logically, use communication components in the

    Integration Directory. A business system is a way of

    specifying a communication component in the Integration

    Directory more precisely (business system component).

    Hope this will hwlp u..
