Rules
Create and apply rules within profiles. A rule is business logic that defines conditions applied to data when you run a profile. Use rules to further validate the data in a profile and to measure data quality progress.
You can add a rule after you create a profile. You can reuse rules created in either the Analyst tool or Developer tool in both the tools. Add rules to a profile by selecting a reusable rule or create an expression rule. An expression rule uses both expression functions and columns to define rule logic. After you create an expression rule, you can make the rule reusable.
Create expression rules in the Analyst tool. In the Developer tool, you can create a mapplet and validate the mapplet as a rule. You can run rules from both the Analyst tool and Developer tool.
