You can create a relationship between a custom metadata object and a PowerCenter object.
Some PowerCenter objects can be used in multiple contexts, used in a single context, or can refer to an original object. The information that a data lineage diagram displays depends on the following PowerCenter object types that you can associate to a custom metadata object:
Reusable transformation or session. An object that you can use in multiple contexts.
When you run data lineage analysis on the custom metadata object, the data lineage diagram displays the PowerCenter object and all instances of the object.
When you run data lineage analysis on any instance of the PowerCenter object, the data lineage diagram displays the associated custom metadata object.
If the reusable object is not used in another PowerCenter object, then the data lineage diagram does not display the relationship between the custom metadata object and the reusable object.
Instance of a transformation or session. An instance of an object used in a single context.
When you run data lineage analysis on the custom metadata object, the data lineage diagram displays the PowerCenter object instance within the context where the instance is used. For example, you relate a custom metadata object to a Lookup transformation instance. The data lineage diagram of the custom object shows the Lookup transformation instance within its corresponding mapping and session context.
Shortcut. A reference to an original object.
When you run data lineage analysis on the custom metadata object, the diagram displays the instances of the original object and all instances of the shortcuts to the original object.
When you reload the custom or PowerCenter resource, Metadata Manager creates or deletes associations based on changes made to the source. For example, you create a relationship between a custom metadata object and a reusable PowerCenter transformation that has one instance in a mapping. In the PowerCenter source, you add another instance of the transformation to a mapping. When you reload the PowerCenter resource, Metadata Manager associates the additional instance of the transformation to the custom metadata object.
