What's the difference between reference parameter and value parameter.

hey,expert

what parameter is reference parameter?

when I made the import in RFC function,the message as follows:

You have defined a reference parameter for a remotely called function module. However, only value parameters are allowed in this kind of function module.

can any expert tell how to solve this problem?

thank you.

A reference parameter : When a parameter is called by reference, the system points to the original parameter without making a copy of it. The function module works with and, if necessary, alters the original parameter and not a copy.

Make the parameter you have defined as "pass by Value".. There is a checkbox in the inteface definition for that..
