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.

mapping parameter represents a constant value ,u decleare
these values at a file and store at a location ,the path
will be declared at session properties and the parameter
name is declered at designer->parameters&variables ----
naming convention is $$-----.when u run the session then it
will take the values from the file
variables ---declearing as same above but for parmeter we
wil declear it as parameter n 4 variable we decler it as
variable ---functionality if u declare it as last updated
date for first run it will take as intial value which u

Answer / basha
Mapping parameter is a parameter whose value does not change
through out the session run.This will take the value from
the parameter file.
Mapping variable value will be saved by session so this
value can be used from the next sessions runs.
