what is rfc
What is RFC? For business applications, it is necessary to communicate and exchange information (in pre-defined formats) with other systems.Hence, there are well defined mechanisms to enable this communication. SAP has also provided us with such mechanism called RFC, which stands for 'Remote Function Call'. RFC is a SAP protocol to handle communications between systems to simplify the related programming. It is the process of calling a function module which is residing in a different machine from the caller program.
