The mapping process pairs objects between the job source and target so that the objects can be compared. You can see and modify pairs using the Mapping tab of the Schema Comparison Job editor.

DB Change Manager automatically maps schema objects based on its interpretation of both schemas. Elements that do not match are initially excluded; you can manually map them prior to running the job.
