Ignore lower limit of 'Between' slicer

[Anonymous]

Hi,

I am using the DATEDIFF function to calculate the age in days of the oldest record by comparing earliest Create Date to the current date - like below:

Earliest Create Date = MIN('IssuesLog'[Create_Date])

Record Age (Days) = DATEDIFF([Earliest Create Date],TODAY(),DAY)

What I want to do is introduce a calendar table to show issues created in a certain period, and show within that period what the age of the oldest record is i.e. keep the upper limit of the date range, but ignore the lower limit.

Record Age (Days) in Period = DATEDIFF([Earliest Create Date],MAX(Calendar[Date]),DAY)

This works to a degree, but if you put a date Slicer on Calendar Date between for example 1/6/2020 and 30/06/2020 then the oldest is always calculated at 29 days even if there was an issue that was created earlier than 1/6/2020. 

Is there a way to make the measure ignore the lower limit, but keep the upper limit?

Hi @Anonymous 

You can use the CALCULATE statement to control filters applied to your calculation.

IgnoreFromDate = 
var ToDate = Max(Dates[Date])
var EarliestCreateDate = CALCULATE(MIN('Table'[Date]), ALL('Table') ,'Table'[Date] <= ToDate)
return DateDiff(EarliestCreateDate,Todate,DAY)
