RFC Function Module

Hi all,

I am using 2 RFC Function Modules, one FM calls another FM. in First FM i have only import parameters (No export,table and changin parameters). in the Second FM i am using both import and export parameters.

When first function module is called from the external system will it by default return the second FM's export parameter values or we need to define the same export parameters for first FM as that of second FM.

Thanks.

Mungala.
