function module can be called within the system.

rfc can called from remote system

RFC is the protocol used to call functions in an R/3 system by a caller external to R/3 or to call programs external to R/3 from an R/3 system.

Functions can only be called via RFC, if they are tagged as RFC functions in the SAP development workbench. They are then called RFC function modules.

A remote function call (RFC) is the call of a function module that runs in a different system to the calling program

RFC is just a FM that can be called from remote system too(destination defined in transaction SM59).

u create rfc function same as normal function only one diffrence is one radio button click which is rfc enabled function when we create fm.

RFC or RFC destination means you define (in transaction SM59) a remote destination, usually to another SAP system

Hello Krithika

The interface of an RFC-enabled function module differs from a "normal" function module in that all parameters must be typed (to DDIC types) and passed "by value" (flag set for parameter in function module interface).

hi,

RFC is a function module, but it is remote enabled meaning it can be invoked from other(remote) systems.

when creating a function module u can make it remote enabled by choosing radiobutton in the attributes.

to call a Remote enabled FM, we do like this

call function '<FM name>' destination '<logical systemsname of partner>'.

RFC concept is very useful in ALE,EDI,also in BAPI where u can access a funtion in SAP from a legacy system also.
