Value Cascades

Value Cascades

Use a value cascade to mask similar columns in different tables with the same masking rules. Use a value cascade when the columns that you want to mask are not related by key constraints. Data masking returns the same values into each column. Configure a group of similar value columns to define a value cascade.
Configure value cascades as similar value columns and define one of the columns as the driving column. If you assign a rule to the driving column, Test Data Manager assigns the rule to all the columns in the group. For example, you configure employee_num column in one table and EmpID in another table as similar value columns. Define employee_num as the driving table. When you assign a data masking rule to employee_num, EmpID receives the same masking rule. The columns in a value cascade must be the same type.
When you view the columns in a project, a driving table shows a number in the
Similar Value Columns
column. The number indicates how many other columns are in the value cascade. The similar value columns do not show a number in the
Similar Value Columns
column.
You can view a list of the columns in a value cascade. Select the driving column in the content panel. Click the
Similar Value Columns
view in the details panel. A list of the similar value columns appears.
To configure value cascades for an XSD source, open the XSD file from the
Discover | Files
view within a project. Select the elements and attributes, and configure similar value columns.
