Seed

Seed

Apply a seed value to create repeatable output for data masking output. The seed value is a starting point for generating masked values.
You can define a seed value from 1 through 999. The default seed value is 1. Apply the same seed value to a column to return the same masked data values in different source data. For example, if you have the same
Cust_ID
column in four tables, and you want all of them to output the same masked values, apply the same seed value when you mask each column.
The TDM administrator can also set a central seed value for all data masking components with repeatable output. The central seed value overrides any other seed value.
