Lineage information for prepare targets
Qlik Catalog generates and persists field-level lineage information when enabled through core_env property: enable_prepare_lineage.
Lineage information is updated on every Validate and Execute operation of a valid prepare job.
A second property (enable.prepare.copy.metadata) will copy metadata from parent field to child field (this property only comes into play if prepare lineage is enabled). Metadata (tags, business description, technical description, business name, blog) is copied from parent to child objects on every Validate and Execute when the property is enabled.
Field-level lineage for prepare targets can be accessed in the discover module on the fields grid: Select the View Details icon, select lineage tab, expand the (caret) icon in parent lineage section to display lineage information details Source Name, Entity Name, and Rule which describes the transform flow and which transform controls were used.

Select the view icon to drill in further on fields for Profile and Profile Distribution.
