Collaboration Technology Support Center – Microsoft – Collaboration Brief June 2005 Interoperability between Microsoft BizTalk Server 2004 and SAP XI 3.0 Tilo Böttcher, SAP Program Manager CTSC, Global SAP Alliance, Microsoft Corporation Jürgen Daiberl, SAP Program Manager CTSC, Global SAP Alliance, Microsoft Corporation Thomas Reimer, Senior Manager IT Consulting, Resco GmbH Christian Brückner, Senior Consultant Microsoft Technologies, Resco GmbH Rüdiger Lühr, Senior Consultant SAP Technologies, Resco GmbH Summary This white paper provides a concept on how to integrate Microsoft BizTalk Server 2004 and SAP XI based upon a scenario of both integration platforms acting as cooperating systems and integrating different parts of the application landscape. The white paper combines conceptional work on a double-hub integration architecture and practical experiences from existing projects. A double-hub integration architecture consisting of Microsoft BizTalk Server 2004 and SAP XI 3.0 encapsulates all SAP centric integration scenarios and interfaces within the XI hub and all other scenarios within the BizTalk hub. To achieve a seamless and comprehensive connection between those two hubs several aspects regarding the different integration layers have to be considered. The white paper covers all relevant aspects required to establish integration at transport, messaging, process management and monitoring layer. At the transport and messaging layer practical walkthroughs demonstrate the steps necessary to connect SAP XI and BizTalk using the existing mechanisms and adapters. In order to provide a blue print for real-life scenarios the tradeoff between Web Services and conventional RFC/IDoc is discussed.
