call function modules in another function group

Here we have two Function Groups and two Function Modules:

Function Group A - Function Module C

Function Group B - Function Module D

As we know, in Function Module C, if we want to get global variables which are defined in Function Group B, we can call Function Module D of which the export parameters are the variables we would use in Function Module C.

Here is the question, what if Function Module C is a RFC function?

I am considering that Function Module C & D may be running on the remote system and local system separately.

Can we still get the value by calling Function Module D in this case?
