Multiple selection filters not working

[Velvetine27]

Hi all,

I wrote a DAX to display data up till the selected month like this : 

%CFR=

VAR selectedYear =

    SELECTEDVALUE ( 'DATE'[Date].[Year] )

VAR selectedMon =

    SELECTEDVALUE ( 'DATE'[Date].[MonthNo] )

VAR start_ =

    DATE ( selectedYear, 1, 1 )

VAR end_ =

    DATE ( selectedYear, selectedMon + 1, 1 ) - 1

RETURN

CALCULATE(([DO] / [SO]),FILTER ( 'TABLE', 'TABLE'[date] >= start_ && 'TABLE'[date] <= end_ ))

Now the issue is that in my visuals if the user selects more than one month, this doesn't work. Do you guys have any suggestions how can I keep the functionality of current DAX while allowing users to select multiple months and it will show data up till the last selected month. So if users choose all months, it should display the entire year of data. Any suggestions appreciated. 

Thanks !

Hi  @Velvetine27 ,

I created some data:

Table:

Date:

Here are the steps you can follow：

1. Create measure.

Flag =
var _selectyear=SELECTEDVALUE('Date'[Year])
var _selectmonth=MAXX(ALLSELECTED('Date'),[Month])
var _start=DATE(_selectyear,1,1)
var _end=EOMONTH(DATE(_selectyear,_selectmonth,1),0)
return
IF(
    MAX('Table'[date]) >=_start && MAX('Table'[date])<=_end,1,0)

Measure =
SUMX(ALLSELECTED('Table'),[DO/SO])

2. Result:

hi @Velvetine27 

 try like:

%CFR=

VAR selectedYear =

    YEAR(MAX('DATE'[Date]))

VAR selectedMon =

    MONTH(MAX('DATE'[Date]))

VAR start_ =

    DATE ( selectedYear, 1, 1 )

VAR end_ =

    DATE ( selectedYear, selectedMon + 1, 1 ) - 1

RETURN

CALCULATE(([DO] / [SO]),FILTER ( 'TABLE', 'TABLE'[date] >= start_ && 'TABLE'[date] <= end_ ))
