This may be a basic question, but I am very new to tableau.
I am having an issue doing a week on week calculation on a rolling sum. for the output I have to have the most recent date as the first column. I have created a running total that restarts at the beginning of each week (Sat-Friday) I did this using the calculated field rolling total, sort order date created maximum ascending. The totals are correct.
When I try using the Percent difference from Calculation it appears to be working out the WoW Difference on the total number of records for that day only, not the cumulative total. Is there a simple way of doing a calculation to do a wow % difference between the two cumulative totals?
