Expression Masking Parameters

Expression Masking Parameters

You can configure parameters for the expression masking technique.
The following table describes the parameters that you can configure for expression masking:
Parameter
Description
Repeatable Output
Determines if the masked value should persist for a given column value. You must enter a seed value when you enable repeatable output.
Alphanumeric Seed
The alphanumeric seed is a key that allows multiple data masking rules to generate the same masked values from the same source values. Define the same seed in each data masking rule that requires the same results for a column. The seed can be any text.
Expression
Accepts PowerCenter expressions and performs a calculation based on values within a single row.
