SAPR3
The SAPR3 component bridges between the SAP system and Fiorano SOA™ Platform 2007 and executes the various services deployed on the SAP system. This bridge receives a request XML and executes SAP BAPIs and RFCs. Every component instance can be customized to access any BAPI using the BAPI browser which allows you to choose any BAPI (prebuilt and custom-built) by browsing the business objects
in the SAP repository.
