I'm creating a simple filter on a tableau measure field to only show impressions over 50. I created a calculated field to do this and noticed that the impression sums have changed causing a (very small) false discrepancy. How do I create a filter that doesn't effect overall sum of values?
For example, without the filter my total is 380,052 impressions but with the filter I have 379,923.
I've tried adding the "Impressions" measure to the "Filters" and adjusting the filter to show 50 or more impressions. I've also tried creating a simple IF statement, such as, sum(if [IMPRESSIONS] > 50 then [IMPRESSIONS] END)
Neither work but I need to create a filter to only include impressions over 50...any ideas?
