Hi Murali,

<u><b> 1.Business System</b></u>

Business systems are logical systems that function as senders or receivers within the SAP Exchange Infrastructure(XI).

Before starting with any XI interface,the Business systems involved has to be configured in SLD(The SLD acts as the central information provider for all installed system components in your system landscape.)

<u><b>2.Third Party</b></u>

eg.For the SAP system a Bank would be a third-party which would be involved in interfaces involving exchange of data(Bill Payment by customer).

<u><b>3.XI(Exchange Infrastructure)</b></u>

It enables you to connect systems from different vendors (non-SAP and SAP) in different versions and implemented in different programming languages (Java, ABAP, and so on) to each other.

Eg.If an interface involves Purchase Order sent from SAP system to the vendor(Non-SAP system)then,the vendor might expect a file.But the Data is in the IDOC(intermediate document) form with the SAP system.Here XI does the work of mapping the IDOC fields and the File fields and sends it to the vendor in the form of a file.

In short,always the scene is Sender-XI-Receiver.

The Sender and the Receiver depends upon the Business you are dealing with.

<u><b>4.Business Partner</b></u>

A person, organization, group of persons, or group of organizations in which a company has a business interest.

This can also be a person, organization or group within this company.

Examples:

• Mrs. Lisa Miller

• Maier Electricals Inc.

• Purchasing department of Maier Electricals Inc.

<u><b>5.Client</b></u>
