What is the admin_last_access field within the answers table?
Answers, Date Admin Last Access
The admin_last_access field within the Answers table refers to the date and time a staff member last opened the answer while editing an incident. Specifically, the answer must be acted upon by an agent within the Incident console (not the Answers console) AND the agedatabase utility must run for the field to be updated. The agedatabase utility runs each night, usually around midnight.
As an example, if an agent were to open an incident and add a link to an answer within the incident, one should see that answer's admin_last_access field update appropriately the next day.
