If you configure connection assignments or linking rules after loading a resource, create the links between objects in the resources to run data lineage analysis across metadata sources.
When Metadata Manager links objects between resources that share connection assignments, Metadata Manager determines if the object is used in other resources using a name-based matching method. The name-based matching method is not case sensitive. For example, a Source Qualifier transformation references “infa_customers,” and the database table name is “INFA_CUSTOMERS.” The name-based matching method creates a link between the Source Qualifier and the database table.
When Metadata Manager links objects between resources that have associated linking rules, Metadata Manager evaluates the expressions defined in the linking rules to link matching objects.
