Distinct Count of ID's associated with a given date from rows with start and end dates.

Hello!

I am trying to get a distinct count of ID's noted within a specific date range. My table has columns with ID's, start and end dates.

I can get the total rows that fall within the date range on any given day from the following:

AL Apt Census =

VAR StartDate = VALUE(SELECTEDVALUE( 'Assisted Living MXC Census'[MOVEINDATE] ) )

VAR EndDate = VALUE(SELECTEDVALUE( 'Assisted Living MXC Census'[ENDDATE] ) )

VAR MinDate = VALUE( MIN( Dates[DayDate] ) )

VAR MaxDate = VALUE( MAX( Dates[DayDate] ) )

VAR CensusPrimary = SWITCH(TRUE(),

SELECTEDVALUE('Assisted Living MXC Census'[PAYORTYPENAME]) = "Primary" || SELECTEDVALUE('Assisted Living MXC Census'[PAYORTYPENAME]) = "Couple",

IF( AND( StartDate <= MinDate, EndDate >= MinDate ) ,

MIN(EndDate, MaxDate ) - MinDate +1,

IF( AND( AND( StartDate >= MinDate, StartDate <= MaxDate), EndDate >= MinDate),

MIN( EndDate, MaxDate) - StartDate +1,

BLANK()) ),BLANK())

RETURN

CensusPrimary

Is there anyway to get a distinct count of a value noted on any given day? I need the distinct count of the ID's assocated with this census number. I am stuck.

Thank you for any help!

I think you might be making life hard for yourself with the nested SWITCH/If when you could be using CALCULATE.

Are you able to share a demo pbix? Fairly sure we should be able to help.

Hi,

According to your description, I can roughly understand your requirement, you want to get a distinct count of ID's noted within a specific date range, right? I think you can try this method to get the expected result:

This is the test data I created based on your description:

You can create a calendar table to be placed into the slicer:

Calendar = CALENDAR(DATE(2022,1,1),DATE(2022,1,5))

Then you can create a measure like this:

Distinct count = var _start=MINX(ALLSELECTED('Calendar'),'Calendar'[Date]) var _end=MAXX(ALLSELECTED('Calendar'),'Calendar'[Date]) return CALCULATE(DISTINCTCOUNT('Table'[ID]),FILTER(ALL('Table'),[Start Date]>=_start&&[End Date]<=_end))

And you can create a slicer and a card chart to get what you want, like this:

You can download my test pbix file below

If this result is not what you want, you can post some sample data(without sensitive data) and your expected result.
