Available Data Masking Rules

Available Data Masking Rules

The
Data Masking
view lists the rules that you can assign to each column of the data source. You can assign one or more rules for a column if the masking rules are available for the column.
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 PowerCenter 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.
In the
Data Masking
view, you must click the
Save
icon after each time you assign a rule. If you do not save the rule assignment before you assign another rule, the Test Data Manager discards the rule assignment.
