Mapping parameters have a constant value through out the session

whereas in mapping variable the values change and the informatica server saves the values in the repository and uses next time when u run the session.

If we need to change certain attributes of a mapping after every time the session is run, it will be very difficult to edit the mapping and then change the attribute. So we use mapping parameters and variables and define the values in a parameter file. Then we could edit the parameter file to change the attribute values. This makes the process simple.

Mapping parameter values remain constant. If we need to change the parameter value then we need to edit the parameter file .

But value of mapping variables can be changed by using variable function. If we need to increment the attribute value by 1 after every session run then we can use mapping variables .

In a mapping parameter we need to manually edit the attribute value in the parameter file after every session run.

How can you edit the parameter file? Once you setup a mapping variable how can you define them in a parameter file?
