Substitution Masking Parameters

Substitution Masking Parameters

You can substitute data with repeatable or non-repeatable values.

produces deterministic results for the same source data and seed value. You must configure a seed value to substitute data with deterministic results.
You can configure the following substitution masking parameters:
Parameter
Description
Repeatable Output
Returns deterministic results between sessions. The
Data Integration Service
saves masked values in the storage table.
Seed
A start number that the
Data Integration Service
uses to return deterministic data.
Dictionary Information
Required. Configuration of the relational table that contains the substitute data values. Configure the following parameters:
  • Dictionary. Displays the relational table name that you select.
