If no rules appear for a column when you click

Masking Rule

, check for the following situations:

The project has no rules for the column datatype.
The project does not contain policies with masking rules.
A data domain that has a preferred rule that you need to use is not in a policy that you assigned to the project.

The

Integration Service

does not mask integers greater than 28 characters.

If a column has a data domain assignment, the preferred rules for the data domain appear at the top of the list in the

Masking Rule

column. If you forget to add a rule to a data domain, you can assign rules from policy preferred rules. The policy preferred rules appear below the data domain rules in the rules list.

You can apply the default data domain rules to multiple columns at a time. Select multiple columns and click

Rule Assignment

. You can choose to assign the default rules in the

Rule Assignment

dialog box.

You can apply a single masking rule and a policy to multiple columns of similar data type. Select the rule from the

Single Rule Assignment

dialog box. For example, you can search for an ID column, select all the ID columns, and assign a single rule, a policy, or both to the selected columns.

When you select mapplet rules, advanced rules, or any rule that uses multiple columns, you must configure a mapping between the source ports and the rule ports. The Test Data Manager notifies you when you need to configure the source to rule port mapping.
