The Solution Key Design Elements Web services Application functions become Web services Self-contained, modularized functionality that can be described, published, discovered, and accessed through open internet standards In addition, all kinds of services that are relevant for classical EAI and remote communication (via adapters) Open syndication of Web services Regardless of location Web-centric Architecture XML and message based infrastructure for open collaboration supporting open standards and leveraging Java, ABAP and.net Central Integration Repository and Directory capturing shared Collaboration knowledge Open for mysap.com e-business solutions and 3 rd party components All customer touchpoints based on open XML and Java technology SAP AG 2003, Title of Presentation, Speaker Name / 8
The Solution Shared Business Semantics Shared Integration Knowledge Business scenarios, business processes, Web services, interfaces, mappings, routing rules,... For a common understanding of how collaborative business processes work Enabling distributed execution Shared classification and discovery of businesses and services Support for UDDI (Universal Description, Discovery and Integration) Loose coupling via XML messaging Asynchronous communication as far as possible Synchronous communication where required Evolution Allow easy and non-disruptive addition of new services and processes Integration of existing and new SAP components Integration of existing customer and 3rd party components SAP AG 2003, Title of Presentation, Speaker Name / 9

Integration Repository Integration Content provided at Design Time Already contains Integration knowledge for mysap solutions Open for Partner and Customer to add collaboration knowledge of non-sap systems Content can be filled from different sources using open standard descriptions (e.g. WSDL) XML and Java based tools Business Scenarios Business Processes Mapping Objects Interface Objects Imported Objects Components (SLD) Integration Repository SAP AG 2003, Title of Presentation, Speaker Name / 11
Integration Repository Business Scenarios Business scenarios Provide overview of business semantics of an integration scenario Show involved communication partners and their roles Outline choreography of message exchange Provide central access to all involved design time objects (like interfaces, mappings) Provide input for configuration Support top-down and bottom-up modeling SAP standard business scenario Supplier Managed Inventory SAP AG 2003, Title of Presentation, Speaker Name / 12
Integration Repository - Interfaces Central place to define and catalog global and component-specific interfaces Interfaces assigned to components Tracks different interface versions Descriptions of all existing BAPI, IDOCs and RFCs Global interfaces and types populate Includes message types and data types for high reusability Based on WSDL (Web Service Description Language, W3C) Outbound and inbound interfaces Synchronous and asynchronous interfaces XML Schema to describe data types Basis for Proxy generation populate Application developer designs a new interface SAP AG 2003, Title of Presentation, Speaker Name / 13
Proxy Generation Key Benefits Separation of Business Application from technical Exchange Infrastructure Platform and programming language independent principles Generation of proxies in Java, ABAP and.net platform Using interface description (WSDL) of Interfaces in the Integration Repository Design time activity Proxy connects to (local) Integration Engine Executes shared integration knowledge (Integration Directory) Proxy Integration Engine Business Function Application System SAP AG 2003, Title of Presentation, Speaker Name / 14
Integration Repository - Mappings Contains preconfigured information for Structural transformation Value mapping Interface Mappings register mappings for interface pairs Message Mappings are used to implement mappings Message Mapping definition in the Integration Repository Graphical Mapping Editor Import schema (XSD, XML) Import IR message types Import archives (zip or jar) Import RFC, IDoc Write own Java functions Mappings are stored in the Integration Repository, selected for business processes in Configuration Time, executed by the Integration Engine at runtime SAP AG 2003, Title of Presentation, Speaker Name / 15
Integration Directory Integration Content provided at Configuration Time Contains productive integration knowledge at customer site Can be derived from Integration Repository during installation and configuration Open for Customer to add collaboration knowledge relevant to non-sap components XML and Java based tools Business Scenarios Business Processes Receiver Determinations Interface Determinations Web Services System Landscape (SLD) Business Partners Integration Directory SAP AG 2003, Title of Presentation, Speaker Name / 16
