This date column on the Course Authorization Permission Config window holds the reminder date for the approaching End Date for the selected active terms.
It is stored on CONFIGURATION_TABL.CONFIG_VALUE where MOD_CE =' RE', FUNCT_CDE =' CRS_AUTH_PERM' and CHAR_CDE = 'REMINDER_DATE'. When this date has passed, a reminder message displays when the Synchronize Course Permissions window is opened.
