Load memberships and terms through an import
What It Does
Imports load holdings and dated coverage one item at a time. Producer keys support repeatable upserts while the data engine reports successful and refused items separately.
The Flow
When Something Fails
One item’s refusal does not undo prior items. The producer must load granted and derived holdings, and affiliation imports are missing. Existing findings cover permissive upserts and resets that retain temporal evidence of deleted records.
