Incorrect Measure Total on Matrix Visual

Hi,

I have the following the following report page with a date slicer and a table.

- The date slicer comes from a date table that DOES NOT have a relationship with my facts table. 

-The "Max" date in the date slicer is used for the "Calculation" measure (DAX below), which essentially is a SWITCH Function that handles the following conditions.

1) If "End Date" <= "Max" date in the date slicer then return the full value of "Dollars"
2) If "Start Date" = "Max" date in the date slicer then return daily rate of "Dollars" (Dollars / (End Date - Start Date)

3) If "End Date" > "Max" date in the date slicer then return the daily rate * ("Max" date in the date slicer - Start Date)

Calculation Dax

 SWITCH(

                TRUE(),

                MAX('Fact Table'[End Date]) <= MAX('3.dim_date_table'[Date]),

                SUM('Fact Table'[Dollars]),

                MAX('Fact Table'[Start Date]) = MAX('3.dim_date_table'[Date]),

                DIVIDE(SUM('Fact Table'[Dollars]),(DATEDIFF(MAX('Fact Table'[Start Date]),MAX('Fact Table'[End Date]),DAY)),0),

                MAX('Fact Table'[End Date]) > MAX('3.dim_date_table'[Date]),

                DIVIDE(SUM('Fact Table'[Dollars]),(DATEDIFF(MAX('Fact Table'[Start Date]),MAX('Fact Table'[End Date]),DAY)),0)*DATEDIFF(MAX('Fact Table'[Start Date]),MAX('3.dim_date_table'[Date])+1,DAY)

                ,

                0

            )

 

On a row by row basis, everything appears to be working as expected. The only issue is that the total amount is not accuate.

 

For example in the screenshot below, we see that the Calculation total is $5,934.01 when it should be $6,319.61

 

I suspect this is due to the lack of row context when referring to the "Max" start and "end" dates for the total calculations, so the max values of the entire dataset are used rather than calculating row by row.

Please let me know if any additional information is needed. Any input is appreciated. Thanks!
