I have a report with a drop-down filter that shows the month-year as the choices. Please see screenshot here:
I was wondering, how can I set the filter up as to show the "Dec-2017" option to show only once, instead of many times as in the screenshot? How can I group this repeating label? Currently, I have this function in the field:
(Date([Opportunity.CreatedDate] - 5/24, 'MMM-YYYY'))
Thank you in advance for your assistance!
