I need to complete the same process for every different region. I need the total top 10 customers in sales for 1) Current Month, 2) Past Year Current Month, 3) YTD 2020 and 4) YTD 2019.
I need these 4 variables for each of the Regions.
I know there has to be a simpler way to do it, than to filter out each region and run the top 10 and join them all back together, but can't seen to find it.
