Rules in Informatica Developer Overview
A rule is business logic that defines conditions applied to source data when you run a profile. You can create reusable rules from mapplets in the Developer tool. You can reuse these rules in Analyst tool profiles to validate source data.
Create a mapplet and validate as a rule. This rule appears as a reusable rule in the Analyst tool. You can apply the rule to a column profile in the Developer tool or in the Analyst tool.
A rule must meet the following requirements:
- •It must contain an Input and Output transformation. You cannot use data sources in a rule.
- •It can contain Expression transformations, Lookup transformations, and passive data quality transformations. It cannot contain any other type of transformation. For example, a rule cannot contain a Match transformation as it is an active transformation.
- •It does not specify cardinality between input groups.
