Looking for some saved search formula help. In a transactions saved search, I am grouping by a field and then summing two amount fields. One of the amount fields is already a case when statement. I then want to get the % difference between those two summed amounts. Any thoughts?

You can still apply the % Difference function to a formula field. calculate the separate statements and apply the function

Where do you find % Difference function? I don't see it in the list of Function options. Is so, how does it work?
