To generate test data, you can apply auto rule, default data domain rule, default global rule, default primary key rule, or default unique key rule to a target column.
View the default generation rules from the
Overview | Properties
tab. Edit the default settings if you want to change the default generation rules that you want to assign to the target columns.
You can apply the default generation rules from the
Define | Data Generation
page. The default data domain rule is the default rule that you configure when you create and run a data domain profile.
After you run a column profile, you can review and finalize the profile results. You can assign auto rule to columns that contain Yes in the Inferred Rule column. When you apply auto rule to a target column, TDM populates the target column with the approved profile results. You must not apply an auto rule to a primary key column because a primary key column cannot contain null values.
