I've been trying to create a filter that filters all completed tickets of a component by the last 3 months, for reporting purposes. I've looked at numerous Altassian posts and this is the best that I've come up with. It still doesn't work because it doesn't like the >= operator:
status = (Resolved, Published, Completed, Declined, Closed, Accepted, Done) >= startOfMonth() AND component = "End Of Life (EOL)" ORDER BY Rank ASC
