In a large business establishment, SAP ERP does not consist of a single system but several integrated systems i.e. CRM, SRM and FICO etc. To handle with such complexities SAP introduced Process Integration (SAP XI/PI), a platform to provide a single point of integration for all systems without touching existing complex network of legacy systems. SAP XI/PI is an integration platform to provide a single point of integration for all systems. This is a powerful middleware by SAP to provide seamless end to end integration between SAP and Non-SAP applications inside and outside the corporate boundary. SAP XI/PI includes SAP XI that stands for SAP Exchange Infrastructure and SAP PI that stands for SAP Process Integration. SAP XI/PI facilitates proper interaction between different operating systems and applications. SAP XI/PI supports B2B as well as A2A exchanges, supports synchronous and asynchronous message exchange and includes built in engine for designing and executing Integration Processes. The SAP PI consists of a hub and spoke structure; the spokes connect with external systems while the hub exchange messages between them. In this course, we will handle SAP XI/PI in details. We will learn the architecture of SAP XI/PI. We will talk about Single stack and dual stack. Then we will understand the concept of Integration Engine, Adapter Engine and Business process Engine. We are going to learn in details several components of SAP PI, ESR Objects and Features. Several topics that we will be discussing in details are Enterprise SOA. Difference between Web service and Enterprise service, overview of SLD(System landscape directory), Features of SLD, software catalog, system catalog, configuration and monitoring etc. The course has been conceived and designed by the experts and it starts from scratch. All the concepts and processes are explained in very simple terms. By the completion of the course, a participant would be able to work like a professional in SAP XI/PI.
