The

masking

task provides dictionaries that contain sample data for substitution masking. When you configure substitution masking, select the dictionary that contains the type of substitute values that you need. The

masking

task performs a lookup on the dictionary that you choose and replaces source data with data from the dictionary.

You can substitute data with repeatable or non-repeatable values. When you choose repeatable values, you must configure a seed value to substitute data with deterministic results.
