I have a table that I add a new snapshot of data to monthly. The date the new data is entered is the Snapshot Date column (Screenshot - Forecasted Data Table attached). I would like to calculate the difference in the column 'Recognized + Projected Revenue (CAD)' between Snapshots. For Example: I would like the Difference in 'Recognized + Projected Revenue (CAD)' in 'Snapshot Date' "May 2016" and 'Snapshot Date' "June 2016" for project = "X" at 'Date' = "July 2016".
I have also attached a picture of how I have configured my Matrix that is displaying the data.
Any help would be very appreciated.
