# Open Positions divided by Hires for time period
I'm working on a report that needs to look at the number positions that were open per month for a 13 month rolling period and divide that by the number of hires that occurred in that same month. Open reqs includes new reqs that were created that month as well as reqs that were still open from previous months.
I have a multi-query report that is pulling back the reqs for a given month using a filter for when the following is not null.
CASE WHEN "Requisition Dates"."First Fully Approved Date" < CURRENT_DATE AND "Requisition Dates"."Latest Cancelled Date" IS NULL AND "Requisition Dates"."Latest Filled Date" IS NULL THEN 'Open'
