Hi,
RFC means Remote funtion call,in XI u have to import the BAPI or the FM to send the data into XI,ID u dont have the Standard IDOC nad u have BAPI to insert the data into SAP R/3 then we go for RFC and for the syncronous scenarios also we go for RFC.
just like how we import IDCO in the same way we have to import RFC into XI.
What is the basic mechanism behind the file to RFC scenario
File to RFC scenario we get data from Legacy system that have to be inserted in to SAP r/3 first we search for the IDOC or BAPI,this is completly depend on the business flow of the data.
what is the difference between RFc and IDoc
RFC is a remote funtion call in which we have the Responce option,were IDOC is a standard structure which is used to insert the data into sap r/3 system.
for RFC scenario we need only RFC connection that will be done in SM59.connection type 3.
