PI Component

The SAP R/3 Plug-In is an add-on to SAP R/3 and the SAP R/3 Enterprise Core. It is an interface that enables the exchange of data between one or several SAP R/3 systems and other mySAP.com components. The SAP R/3 Plug-In supplies the mySAP.com components with transaction data and master data in real time. It also makes it possible to use mySAP.com application components, such as SAP APO or SAP CRM, together with certain mySAP.com industry-specific components. All mySAP.com industry-specific components based on SAP R/3 4.6B or higher SAP R/3 releases also require the SAP R/3 Plug-In.
