I built a simple Matrix in SSRS. I'm just trying to add a Grand Total to the right of December. In the month header It should say Total
and for each year it should have the total for each month from the corresponding year. The row parameter is an account manager.
For Accountmanager it should have a total for all the 2014, 2015, 2016, and 2017
The final result should look like a layout like this minus the colors.
