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.
Unlike a mapping parameter, 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.
