oh such a big question!
parameter withn values are generally created in a notepad
in the specified location.IN the mapping go to designer--
>mappingparameters/variables->u set the parameters there .
coming to the usage in realtime what we do is we will
create the source and target connection information in the
parameter files.
one simple example to make u understand it's use is
let's take dollar and rupee relation.dollar value is not
conatant everday it will change ,so u can't change u r
mapping every day,hence what u will do is u will create the
mapping as per the requirement but u will save the dollar
value in the parameter file .so if u want to change it's
value u will change the parameter file not the mapping.
if u didn't get let me knoe i will answer again.
