FDG is a tool provided by QTP which generates the function 
definition in vbscript format.After that u need to write 
the logic what to do in the vbscript

This is correct answer than previously given by me

QuickTest provides a Function Definition Generator, which 
enables you to generate definitions for new user-defined 
functions and add header information to them. You can also 
use the Function Definition Generator to register a 
function to a test object. You fill in the required 
information and the Function Definition Generator creates 
the basic function definition for you. You can then copy 
the definition to a library file and associate it with your 
test or component, or you can copy the definition directly 
to a test script in the Expert View. You can complete the 
function by adding its content (code).

Function definition generator :

          it is used to know all bulit in functions in QTP
   and help to write VB script for unknow objects.
         we can define the objects in QTP we can store 
these objects in some ware, we can call these objects as 
our require ments, because of these what ever objects we 
are using those objects not necessary to store it in object 
repository.
