In previous post the solution was to run batch job Administration > Periodic > Notification clean-up as a part of your maintenance plan. Now we have follow up question: how to set up this batch job to remove messages older than 1 month.
To achieve it we can use static function monthRange (public static str monthRange(int relativeMonthsFrom = 0, int relativeMonthsTo = 0)) of class SysQueryRangeUtil. So now we can schedule Notification clean-up to run every month with following parameters:
It will delete all notification between 2 month ago till 1 month ago.
