output returns deterministic values. Use repeatable masking when you run a
masking
task more than once and you need to return the same masked values each time it runs.
Configure repeatable output if you have the same value in multiple source tables and you want to return the masked value in all of the target tables. The tables in the target database receive consistent masked values.
For example, customer John Smith has two account numbers, 1234 and 5678, and the account numbers are in multiple tables. The
masking
task always masks the name John Smith as Frank Martinez, the account number 1234 as 6549, and the account number 5678 as 3214 in all the tables.
Enter a seed value when you configure repeatable output. You can configure a dictionary file with data values that you can replace when you use substitution masking. When you configure repeatable output, the
masking
task returns the same value from the dictionary whenever a specific value appears in the source data.
