You can define a seed value from 1 through 999. The default seed value is 190. Apply the same seed value to a field to return the same masked data values in different source data. For example, if you have the same Cust_ID field in four tables and you want all of them to generate the output with the same masked values, apply the same seed value when you mask each field.

You can enter the seed value as a parameter. Seed value parameter names must begin with $$. You can include an underscore (_) in the name but you cannot include other special characters. Add the required parameter and value to the parameter file and specify the parameter file name at run time.

You cannot use a seed value for random and custom

masking

rules if the source data type is numeric.
