Maping parameter represents a constant value that yoU can
define before running a session. A mapping parameter retains
the same value throughout the entire session. When you use
the maping parameter , yoU declare and use the parameter in
a maping or maplet. Then define the value of parameter in a
parameter file for the session. Unlike a mapping parameter,
a maping variable represents a value that can change
throughout the session. The informatica server saves the
value of maping variable to the repository at the end of
session run and uses that value next time yoU run the session.
