Configure the purge criteria
Purge transactions determine when a record is purged, by determining the current date and subtracting the retention days that are specified in the purge criteria. If the timestamp on the table is less than or equal to the value of current days minus retention days, the record is purged.
You can define purge criteria rules for data purge not related to specific document types. Purge is the process by which old data is removed from the system database. A purge minimizes the number of unused database records to increase search efficiency and reduce the size of the required physical disk. Therefore, it is recommended that you set up purge criteria for your staging and data mart database.
