We had a request from our Development department to be able to schedule a Full Bio based on a list of anyone updated in past week.
This required a new list builder field to be able to check on records update in the last week.
We created a new List Builder field in T_KEYWORDS as follows:
Description: Last Updated (from Audit Tbl)
Data Type: Date
Edit Mask: Date
Detail Tbl: TA_AUDIT_TRAIL
Detail Col: max(!.date)
Hope this info is of help to someone else.
