I have Equipment that I am tracking utilization for by calculating the meter reading at the end of the week and then need to find the meter reading from 30 days before that. The goal is then to subtract the two to find the utilization for that period and plot on a graph. At the moment, I am struggling with getting the meter reading from 30 days before the end of the week. I have been trying measures similar to this:
Hour Meter 30 Days Ago =
VAR _EndDate = SELECTEDVALUE('ISO Date Table'[ISO EOW])
VAR _StartDate = _EndDate -30
VAR _MinDate = CALCULATE(MIN('IW Data'[DateReported]), REMOVEFILTERS('IW Data'), CALCULATETABLE('ISO Date Table', 'ISO Date Table'[DateReported] >= _StartDate))
RETURN
CALCULATE(
MIN('IW Data'[HoursDeadman]),
CALCULATETABLE(
'ISO Date Table',
'ISO Date Table' [DateReported] = _MinDate
)
)
.
Sample data is :

Any assistance will be greatly appreciated.
