Assigning Single and Multiple Masking Rules

Assigning Single and Multiple Masking Rules

You can assign multiple masking rules to a column. To assign more than one rule to a column, create a duplicate row and update the rule. You can assign the default data domain rules to multiple columns at the same time. Assign a single masking rule or a policy or both to multiple columns of similar data type.
