If you’re referring to the scan as a whole then you could use a similar query like the one mentioned here that Holly gave you:
In her query that she provided you could remove the WHERE statement and add that column to your query
SELECT site_id, MAX(scan_id) as scan_id, status_id
FROM dim_site_scan
JOIN dim_scan USING (scan_id)
GROUP BY site_id, status_id
The status_id would be of the of the whole scan though of course and not specific to an asset. Not sure if this is what you were referring to.
