While implementing the SAP ERP in a large business establishment, it is found that not all sections can be brought under the SAP ERP. Many of the business sections may have their own proprietary tools which are highly complex and may not be possible to be replaced. They run parallel to the SAP System. They are called the Legacy Systems. Then it becomes necessary to integrate between the SAP Systems and such pre-existing non-SAP System. This is where the SAP PI comes into play.
Why do we need SAP PI
Apart from Legacy Systems, 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 a platform to provide a single point of integration for all systems without touching existing complex network of legacy 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 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. The source system is known as the sender system and the target system is known as the receiver system. The PI is not a single component, but rather a collection of components that work together flexibly to implement integration scenarios. The architecture includes components to be used at design time, at configuration time and at run time.
We can divide the SAP PI into several areas
Configuration and Monitoring
The System Landscape is a central repository of information about software and systems in data center and simplifies the administration of your system landscape.
In Configuration and Monitoring we can monitor the messages and adapters.
