What is SAP PI?

SAP PI (or Systems Applications and Products Process Integration) is a tool that allows companies to integrate systems with a variety of connectivity, formatting, and protocol requirements. This system makes it possible to create software solutions without having to address every possible networking environment. As a type of middleware, SAP PI uses a transparent design to make it easier to provide solutions for customers, and it is designed to provide a single point of integration for all systems, both inside and outside of a company.
