Get data for current and last month based on date slicer

[sainig546]

Hi,

I am currently working on something which requires me to get data from start of last month to current date  and the data should change based on the month,year selected in slicer. I searched for different ways  but none are giving desired result

example data set

machine_id	customer	date
1000	d1	2021-11-15
1001	d1	2021-12-15
1002	d2	2021-06-15
1003	d3	2021-07-15
1004	d4	2021-07-16

So if we select august 2021 in slicer it should show count of machines as 3 and if nothing is selected in slicer than it should show 2

i do not want to change anything in my date slicer

I am new to powerbi and not able to get anywhere with this problem 

i am currently using a query similar to this

measure=CALCULATE(DISTINCTCOUNT(Table[machine_id]),DATESMTD('Dates'[Date]))

can anybody help me with this ?

Thanks!

Hi, @sainig546 

If we get data for the last month and the current month, when the slicer is not selected, the count is from November to December, then the result is 2. But when August is selected, why is the count 3 instead of 2?
There is data for July but not for August.

Or what you want to do is accumulate the counts to date?

Could you please consider sharing more details about it and posting expected result so it is clear on what needs to be implemented?  And It would be great if there is a sample file without any sesentive information here.

It makes it easier to give you a solution.

Hi, @sainig546 

Try to create a measure:

Measure = 
var _date=MAX('Calendar'[Date])
var _Count=
    CALCULATE(
        DISTINCTCOUNT('Table'[machine_id]),
        FILTER(ALL('Table'),'Table'[date]<=_date&&'Table'[date]>EOMONTH(_date,-2)
            )
        )
    
return _Count

Result:

Please refer to the attachment below for details. Hope this helps.

@sainig546 , Based on what I got, Try measure like

This month =
var _max = maxx(allselected(Date),Date[Date])
return
calculate( DISTINCTCOUNT(Table[machine_id]), filter(all('Date'), 'Date'[Date] <=_max))

last month =
var _max = eomonth(maxx(allselected(Date),Date[Date]),-1)
return
calculate( DISTINCTCOUNT(Table[machine_id]), filter(all('Date'), 'Date'[Date] <=_max))

Hi amit,

Can we somehow check in a measure if there is any value selected in the slicer.

For example in most languages we can give if than statement 1 else statement 2

using that may be we can provide default value for this measure if nothing is selected in slicer and if a date is selected in slicer than it will be given

like if slicer is null than current month else ...

not sure if this is possible here

Thanks

can we combine the dataset for both current month and last month in a single measure

Also when i am not selecting any month in slicer its not showing correct data .

if there is no date selection in slicer than it should show data for last month + whatever data we have for this month.

I cant change anything in slicer because i am using report level slicer and this requirement is specific to only this measure rest measures will show all data by default
