Which of the following is true?
-
Mapping parameters have a constant value through out the session.
-
In mapping parameters, values change and the Informatica server saves the values in the repository and uses next time when you run the session.
-
Mapping parameters cannot be used in any expressions within transformations.
-
Value of mapping parameter can be changed using functions.
Mapping parameters in Informatica have constant values throughout a session runtime - they are set before the session starts and do not change during execution. In contrast, mapping variables can change during session execution and the server saves their values for reuse. Parameters cannot be used in all transformations (there are restrictions), and their values cannot be changed using functions - they are set at session start.
