    RFC means remote enabled FM

    RFC FM can be called from different systems also

    but FM can be called within the server only

    FM handles exceptions but RFC won't

    FM, we can pass variable by using pass by value and pass by reference

    but in case of RFC we send the variables using pass by reference only.

    RFC:

    Remote Function Call (RFC) is a call to a function module running in a system different from the caller's. The remote function can also be called from within the same system, but usually caller and callee will be in differene system. RFC allows for remote calls between two SAP Systems (R/3 or R/2) or between an SAP System and a non-SAP System.

    FUNCTION MODULE:

    Function modules are special external subroutine stored in a central library. The R/3 system provides numerous predefined functin modules that you can call from your ABAP/4 programs. The function modules have global presence and can return value.

    REgards.

    Hi,

    RFC is Remote Function Call. RFC enabled function module can be called remotely.

    That means If we have two systems S1 and S2. Suppose if the function module f1 is in S1.

    If S2 requires the same function as f1 then it can call f1 when f1 is RFC enabled. In this case f1 will be executed in S1 and the results are posted to S2.

    Regards
