Hi Paul, The CumulativePeriod operator in an aggregated measure is what you would use to perform this type of task. https://support.sas.com/documentation/cdl/en/vaug/67500/HTML/default/viewer.htm#n1lxnqfip132can1hdzuerib7i76.htm Unfortunately, you cannot display cumulative values by day for a year other than the current year. You can compare cumulative values by month (or by quarter) to the previous year (or quarter). You can display cumulative values by day for the current year, month, quarter. It is conceivable there's some workaround I'm not aware of. Thanks, Sam
