Hi Team , i would like to calculate a cumulative sum - I am using the formula "cumulative_sum (group_unique_count (Application Id,First Date per Application ),Date)" but getting error "2nd argument to a group function should not be aggregated." Here the "First Date per Application" is basically the min of the date from each week date. I create "First Date per Application" in the formula and the using this in the cumulative sum. Can you please help ?
