Answer Posted / prasanthi
RFC and FM are similar but the difference is RFC is remote
enabled function module means we can call RFC from any stack of SAP.
Suppose we made a FM using ABAP code and that FM is required to be used in application using SAP portals,in that case we make that FM remote enabled(then it becomes RFC) and we can call that RFC.
FM can be called only from R/3 whereas RFC allows for remote calls between two SAP Systems (R/3 or R/2) or between an SAP system and a non-SAP System.
We can pass values or references to FM whereas only values to RFC.
