When you create a non-reusable transformation in a mapping, the transformation parameters are mapping parameters.

To override the default parameter values in the transformation, complete one of the following tasks:

Reconfigure the mapping parameters.
Configure a parameter set or parameter file to override the mapping parameters.

For example, you can create a non-reusable Filter transformation in a mapping and set a parameter for the Filter transformation. The Developer tool duplicates the transformation parameter and creates a mapping parameter. To override the transformation parameter, reconfigure the default value of the mapping parameter, or configure a parameter set or parameter file to override the mapping parameter.
