Cumulative / running total start at Zero based on Calender slicer

[PVO1]

Hello,

Currently I'm using the measure below to calculate my running total sales. This works fine, except;

I would like recalculate the running total for each slicer adjustment. At the moment it starts the total based on latest results, but I would like to start at 0.

For example:

No slicer adjustment (working as intended):

Month	Week	CumSales
1	1	100
1	2	200
1	3	300
1	4	400
2	1	450
2	2	500
2	3	550
2	4	600

Current results when slicing to month 2 (not intended)

Month	Week	CumSales
2	1	450
2	2	500
2	3	550
2	4	600

Desired result when slicing to month 2

Month	Week	CumSales
2	1	50
2	2	100
2	3	150
2	4	200

CumSales =
if(
  MIN(Cal[Date]) <= CALCULATE(MAX(Sal[Sales date]); all('Sal'));
    CALCULATE(SUM('Sal'[Sales])+0
      ;FILTER(ALL(Cal[Date]);Cal[Date] <= MAX(Cal[Date])))
)

Thanks for your feedback Greg. Tried to make it clearer with examples instead of text.

This challenge took my entire day 🙂

I think I just found it!

CumSales =
if(
  MIN(Cal[Date]) <= CALCULATE(MAX(Sal[Sales date]); all('Sal'));
    CALCULATE(SUM('Sal'[Sales])+0
      ;FILTER(ALLSELECTED(Cal);Cal[Date] <= MAX(Cal[Date])))
)
