Sum the sum of values for first and last date

[bingbadabom]

I have a table that looks like this. The values presented here are filtered with a slicer.

I would like to sum the values for the first date (feb 19th) and the last date (feb 22nd). I've tried adapting solutions i've found for almost similar problems but with no luck.

Or you are still confused about it, please provide me with more details about your table and your problem or share me with your pbix file from your Onedrive for Business.

Hi @bingbadabom ,

Based on your description, you can create some measures as follows.

_sum = 

var selected_max=MAXX(ALLSELECTED('Table'),[date])

var selected_min=MINX(ALLSELECTED('Table'),[date])

return

SUMX(FILTER(ALL('Table'),[date] in {selected_min,selected_max}),[value])

_subtract = 

var selected_max=MAXX(ALLSELECTED('Table'),[date])

var selected_min=MINX(ALLSELECTED('Table'),[date])

var x1=SUMX(FILTER(ALL('Table'),[date]=selected_min),[value])

var x2=SUMX(FILTER(ALL('Table'),[date]=selected_max),[value])

return

x1-x2

Result:

Hope that's what you were looking for.

@bingbadabom , Try a measure like

measure =
var _max = maxx(allselected(Table), Table[Date])
var _min = maxx(allselected(Table), Table[Date])
return
calculate(sum(Table[value]), filter(Table, Table[Date] =_min || Table[Date] =_max))

This helped me a lot by the way. Thank you.
But if i need to sum each date by itself and subtract the two numbers?

calculate(
    sum('Table'[Value]), filter('Table', 'Table'[Date] =_min) 
    -
    sum('Table'[Value]), filter('Table', 'Table'[Date] =_max)
)

I get the following error message "A function 'FILTER' has been used in a True/False expression that is used as a table filter expression. This is not allowed."

_max and _min returns the same date. I tried replacing MAXX with MINX but then the date went too far back, it seems that it does not take the slicer values into account

Edit:
This took care of my date problems

var _max = CALCULATE(LASTDATE('Table[Date]), ALLSELECTED('Table[Date]))
var _min = CALCULATE(FIRSTDATE('Table[Date]), ALLSELECTED('Table[Date]))
