Ensuring A2A and B2B Integration 

This IT scenario variant describes the integration of SAP NetWeaver and Microsoft BizTalk server and between SAP NetWeaver and the IBM WebSphere Business Integration (WBI). Using SAP NetWeaver you can keep the benefits of the functionality based on the other products, but enhance it using the SAP NetWeaver features.

A common problem IT organizations faces is how to integrate data and communicate across heterogeneous applications. Message-oriented middleware and enterprise application integration solutions solves this problem. Today’s IT landscape has become more complex with the need for applications to communicate and collaborate across corporate boundaries with customers, partners, and suppliers, as well as product boundaries. Messaging is a proven technology to interconnect between systems based on different technologies, leveraging point-to-point and mediated brokering communications. SAP NetWeaver supports such standards, such as the Java Message Service (JMS).

Architecture of the Scenario Variant

SAP NetWeaver PI can use a SOAP connection to connect to the Microsoft BizTalk server. Again, you can use the SOAP connection to IBM WBI.

Integration with IBM WBI using SOAP

The SAP NetWeaver interoperability for IBM WBI is based on the SAP NetWeaver PI SOAP adapter. The SAP NetWeaver:

●      Uses SOAP over HTTP or HTTPS connection for exchanging data synchronously.

●      Supports requests and events processing.

The PI component includes the technical SOAP adapter that allows these two products to work together:

Integration with IBM WBI using JMS

The Process Integration JMS adapter for IBM WBI:

●      Exchanges XML messages.

●      Transfers the XML messages to WBI business objects and vice versa.

●      Uses JMS to exchange asynchronously data.

Benefits

The SAP NetWeaver platform enables you to work seamlessly with other common messaging infrastructures (IBM and Microsoft) to leverage current investments and add value with SAP NetWeaver Process Integration (PI).

Required or Optional Installable Units

To use this IT scenario you require the following installable units:

●      Process Integration (PI)

IT Processes of the Scenario Variant

Process	What you should know…
Designing Integration Within SAP NetWeaver Process Integration	In this process, you create and manage the design objects that your need for your integration scenario.
Configuring Integration Within SAP NetWeaver Process Integration	In this process, you configure the required integration objects.
Designing and Configuring Integration Within non-SAP	You have to design and configure the relevant integration scenarios including business objects, mapping, routing and so on, also on the non-SAP integration technology.
Handling Messages Across SAP NetWeaver and Non-SAP	This process does not involve user actions. Incoming messages are processed and sent to the relevant receiver. A message can include integration processes while doing this. It is important where the process flow is initiated. For example, the SAP NetWeaver PI might have to determine the receiver and all relevant steps in getting a message, or might have to send the XML message using technical adapters to the non-SAP integration technology.
Monitoring Processes	In this process, you monitor message processing, including throughput and performance on the appropriate integration technology.
