SAP Exchange Information


Home » Exchange Information


Overview

The following graphic shows the components that make up the SAP Exchange Infrastructure as well as some applications that are integrated through the exchange. The applications comprise SAP applications as well as 3 rd party applications. The integration is achieved by exchanging XML based message objects through the Integration Server. To adopt different application Systems the Integration Server does comprehensive routing and mapping using specific integration data out of the Integration Directory and Integration Repository as well as system specific data of the System Landscape Directory.


The SAP Exchange Infrastructure consists of the following components:

  • System Landscape Directory

  • Integration Repository

  • Integration Directory

  • Integration Server

    • Integration Adapters

  • Integration Clients

Applications need the following proxy components to use the SAP Exchange Infrastructure directly and without adapters.

  • Proxy Framework

    • Proxy Generator

    • Proxy Runtime

Integration Server (IS)

The Integration Server is the central part of the SAP Exchange Infrastructure. It receives messages from the sender applications and then applies routing and mapping rules to these messages and finally sends them to the receiving application. Each SAP Web Application Server has the Integration Server Software built in but it is the specific configuration that activates its role as a central Integration Server.

Integration Adapters (IA)

Adapters are used to convert various protocols and data formats into the Integration Servers XML based message objects and vice versa. The Integration Server comes with some built in adapters but most adapters are additional components.

Integration Repository (IR)

The Integration Repository provides collaboration knowledge available at design time, for example, mappings, interfaces, and components. It is built in Java and follows (J2EE) standards. The information in the Integration Repository is used by the Integration Directory, which adds configuration-specific information that is needed for execution

Integration Directory (ID)

The Integration Directory contains detailed collaboration knowledge about the current system landscape around the SAP Integration Server. It is a description of routing rules, active services, executable mappings and the specific system landscape. The Integration Directory details the information from the Integration Repository that is specific to the configuration

System Landscape Directory (SLD)

The System Landscape Directory is composed of the Component Repository and the Landscape Directory. The Component Repository includes a description of all SAP Components whereas the Landscape Directory includes a complete description of the actually installed SAP system landscape.

Clients

Integration Server

The Integration Server can be accessed using the standard SAP Gui frontend.

Integration Repository and Directory

The Integration Repository and Directory require specific Java client software which is stored on the Integration Server and will be automatically installed on the client side using Java Web Start. This client software can be used during design time to develop new interfaces and mappings and to configure services, routings and mappings.

System Landscape Directory

The System Landscape Directory can be accessed using a standard internet browser.

Proxy Framework

The Proxy Framework consists of the Proxy Generator and the Proxy Runtime. The Proxy Framework for ABAP (generator and runtime) is part of the SAP Web Application Server and no specific installation is needed.

Proxy Generator for Java

The Proxy Generator for Java is used to generate proxies (Java Classes) for application programming. It makes use of the Integration Repository which contains all interface definitions.

Java Proxy Runtime

The Proxy Runtime for Java is mandatory for all Java programs to exchange messages with the SAP Integration Server. In doing so the proxy runtime converts the used java classes into XML messages. These XML messages are sent to the Integration Server using http protocol.
