Mapping variables and mapping parameters
Elucidate briefly what is the mapping variables and mapping parameters?
Expert
Mapping parameter represents a steady value which you can describe before running a session. A mapping parameter retains the similar value during the whole session.
When you employ the mapping parameter, U declares and employs the parameter into a mapping or maplet. Then it defines the value of parameter in a parameter file for session.
Unlike a mapping parameter, a mapping variable represents a value which can alter during the session. The informatica server keeps the value of mapping variable to repository at the end of session run and uses which value next time you run in the session.
