Why we have to create Mapping Parameters or Variables ?


You can use mapping parameters and variables to make mappings more flexible. 
You can Reuse a mapping by varing the parameters and Variables. 

Represntation
$$parametername/$$variablename

Parameters
A mapping parameter represents a constant value that you can define before running a session. A mapping parameter retains the same value throughout the entire session.

Variables
A mapping variable represents a value that can change through the session. The PowerCenter Server saves the value of a mapping variable to the repository at the end of each successful session run and uses that value the next time you run the session.
