Business Service and Business System

[Former Member]

Hi All,

We use Business System if it s SAP system and for legace of any other system(JDBC,JMS,File,HTTP) we use Business Service which is known as Communication Component in the PI 7.1.

But,Please tell me the need of using Business System and Business Service?

Also,please tell me about the Technical System.Do we need to use it in Value Mapping when we create the Value Mapping Table?

Thanks in advance.

Hi Shweta,

we define about the systems in the SLD which are going to be integrated.

Let me explain about all the four cases which we do integration :-

Note: Third Party can be FTP, JDBC,MQ etc..

Case 1) SAP-SAP

Case 2) SAP-Third Party

Case 3) Third Party -SAP

Case 4) Third Party -Third Party

For all the above 4 cases wherver SAP is there we should create Business system not Business Service.

you can have a question here why ? and what is Business System

Here is the answer..

Business System is actually logical system (Client) . in SAP we have a client concept. client is an independent entity of organization which stores the data logicall separated from other entity of the Organization. normally to open any application we require user id and password but while opening SAP App server it asks user name , Pwd and Client. there you can understand the SAP system which you are trying to access may have many clients (not more than 99) which uses the same Database( partitioned by Cleints)

so in our integration we need to tell which SAP logical system we are going to integrate .. we define techincal system first which contains physical details about the sap sytem (name, port etc.. then you can add clients to technical system . we can add all the clients to the technical system. then once tehnical system is defined then we need to create Business System . while creating Business System you should specify the technical system and which client you are going to use from the technical system which you added in business sytem .. (business system will take only one client).. and give logical system name same as which you defined in BD54 in SAP.so finally your business system has everything like all the sap system details and which client..

For all the above cases wherver third party is there, its not mandatory to create business system coz there will no client concept in any of the third party system . client concept is only in SAP. if you know all the detials about third party like port etc then you can very well create business system but you may have a doubt while creating business sytem for third party what should we give the client (logical system name) here you can give any name.

if you do not want to create business sytem for third party then you can very well create Business service which doens't need to give any system details..thought business service doesn't cotain anything we need this to virtually identify Source/Target system .

Hope it clarifies..

give me a shout if you need more details.

Hi Shweta,

1) We create Business system in SLD provided if we know all the details of the System.

if we Know all the details of the third part systems (host,port etc ), then we can create Business system for third party systems in SLD.

A business system, which is associated with an AS ABAP

A business system, which is associated with an AS Java

A business system, which is associated with a standalone Java application

A business system, which is associated with a third-party technical system)

If you don't know Technical deatils simply Create business service in ID.

2) no need to use any technical system while creating value mapping table.

Hi,

a Business Service has no SLD entry and has therefore neither transport target nor allocated products / softwarecomponents. This is only for small environments or test cases acceptable.

A technical system exist only in the SLD, you do not need to care about that in a value mapping.
