Hello Ramu,

Use

Two SAP XI 3.0 Integration Servers are used to exchange messages between the system landscapes of two business partners.

Description

An SAP XI Integration Server of a business partner is connected to the SAP XI Integration Server of another business partner. Both use SAP XI message protocol to send or receive messages.

When an SAP XI Integration Server receives a message from another Integration Server it understands the message format and so processes the message.

Example

A business partner that uses SAP XI wants to send a message to another business partner who also uses SAP XI .

· The message is sent between the Integration Servers in SAP XI message format

· The Integration Server of the second business partner then sends the message to the relevant business system

Integration Engine

Purpose

The Integration Engine enables you to process XML messages exchanged between applications in heterogeneous system landscapes. Both applications of SAP components and external applications can communicate with the Integration Engine.

Using adapters, the Integration Engine can also process IDocs (Intermediate Documents) and RFCs (Remote Function Calls). This option is available for applications that have already defined IDocs or RFCs, as well as for applications of SAP components that do not yet have access to the proxy generation functions.

Integration

The Integration Engine is the runtime environment of the SAP Exchange Infrastructure. The following are examples of other important parts of this infrastructure:

· Proxy Generation

· Integration Repository

· Integration Directory

The integration processes involved can take place between heterogeneous system components within a company, as well as between business partners outside company boundaries.

Features

The Integration Engine, as a runtime component of SAP Exchange Infrastructure, has the task of receiving, processing, and forwarding XML messages. During message processing, collaboration agreements are evaluated, the receivers are determined, and mapping activities are executed.

The individual processing steps are called pipeline services and are defined in pipelines. It is the task of the Integration Engine to process these pipelines correctly and consistently. To guarantee this, you must configure the Integration Engine accordingly and monitor the message processing. Both event-driven message processing and prioritized message processing are possible.

Thanks,

Satya Kumar
