RFC enabled function module can be called from any where outside SAP also. At the time of builiding FM there will be no idea from where it might get called in future.

If the call is from outside SAP, then passing by reference will not be possible. Hence passing by value is mandatory

Answer / anil

When ever we are using RFC enabled FM's we should pass pass any values by pass by value only.because RFC may be used by other different systems. if we pass by reference that system may have that pass by value so that system gets confuse to which value have to take. so that why's we should pass by value only.
