Answer / ajith kumar

RFC is used to call the function module from the remote
system, where as normal functin module is used within the
system.

Answer / ashok

Shameer is right.

Remote function modules can only be called by value, but the normal function modules can be called either by value or by reference.

Answer / shameer

Dear,
All the above said answers are correct there is one more
question unanswered. What is different RFC doing and not the
fn module?
The die ifference is in the way parameters are passed the
import export n the table parameters.
In fn module its by reference(passing memory address) if a
parameter's address is passed will the remote system
identify it ? wouldn't hence the concept RFC evolved to
solve it the mode of passing data is by value.
Cheers.

RFC is Remote Function Call which can be used to execute
the function module on remote system to get the required
data.To call the function module remotely,we have to enable
the remote call radio button located in the attribute of
the function module.
Normal function module is one which can be used to
execute the function module in the local system to get the
required data.

Hi,
The Difference between RFC and Normal Function Module is
RFC Stands for Remote Function Call and Normal Function
Module is without RFC Connection.For a Successful RFC
Connection one should check OS level(Ip Address and
HostName fo Target Machine),Logical System Name(Sale/BD54)
and Communication User(SU01).Where as for Normal Function
all this is not required.
