Welcome to the community forums. I have supplied one method of arriving at a view that I believe is similar to the one desired. Utilizing Table Calculation functions we can summarize totals within the view under most circumstances. In this case, I have utilized Window_Sum() functions to arrive at totals for all Sales and totals for all Difference of Sales. Note that I have utilized the function
If last()==0 to limit the result to one instance rather than returning the total for every [Order Date] within the view. I then created a new view to show just the totals so that I could place these alongside the original view within a Dashboard.
Personally I found the original view a bit difficult to read as I would move Years to the last field on the Rows shelf and Customer Segment to the Columns shelf (as in Sheet 4) but that's a matter of preference. I left this view in place on Sheet 4 though as it is the one I used to build out the Totals.
Others may have ideas as well but verifying these are the sorts of results desired would be helpful.
