of dates that updates based on the date and time you run the report. For example, on the first of every month, you’d like an emailed report of all circulation activity in the previous month. You can use advanced date functions in filters to setup these types of reports. Date Filter: [Data for Circulation Reports].[Circulation Events].[DATE_EVENT] between _first_of_month (_add_months (current_date,-1)) and _last_of_month (_add_months (current_date,-1)) Function Breakdown: • Current_date: function calculates the date on the day the report is run • _add_months (current_date,-1): calculates the month, then subtracts the month by 1, giving you last month • _first_of_month / _last_of_month: calculates the first and last days of last month Relative Date Filters
