Get the value from last day of month

[Anonymous]

Hi

I have two tables: Calendar and Values

The Calendar has date and year-month field, something like:

Date             | Year-Month

01-01-2019  | 2019-01

25-02-2019  | 2019-02

...

And the values table has the values for each day:

Date             | Value

01-01-2019  | 19233

31-01-2019  | 16000

25-02-2019  | 18000

...

I need to create an expression in DAX to get the last value for each year-month in a graph that has the year-month dimension as axis.

How can I achieve this?

Thanks!

You may also try this: On you calendar table, create a new Column called myEOM

myEOM = if(Calendar[Date] = EOMONTH(Calendar[Date],0),Calendar[Date],blank() )
In other words, is this is the last day of the month, return date, otherwise, return Blank() an empty value (not zero, more like NULL). Then reference that column on your report, it should show only values for the end of that month (as long as you have the month's full info, won;t show anyhthing MOnth To Date)

Hi @Anonymous 

Sample pbix here

First of all, you should make sure you Calendar table contains contiguous dates (wasn't quite sure from the sample you posted).

Then with your Value table related to you Calendar table on the Date column, here are a few ways you could write the measure depending on the exact requirements:

First define

Value Sum = 
SUM ( 'Value'[Value] )

Measure 1: Return Value sum on the last date of whatever date range is selected:

Value on last date of selected period = 
CALCULATE ( 
    [Value Sum],
    LASTDATE ( 'Calendar'[Date] )
)

Measure 2: Return Value sum on the last date of whatever date range is selected for which the sum is nonblank:

Value on last date of selected period containing data in Value table = 
LASTNONBLANKVALUE ( 'Calendar'[Date], [Value Sum] )

Measure 3: Return Value sum on the last date of the month of the max date selected (could be outside the filtered date range):

Value on last day of month of max selected date = 
CALCULATE (
    [Value Sum],
    ENDOFMONTH ( 'Calendar'[Date] )
)

Regards,

Hi @Anonymous 

try a measure

Measure = 
var _lastMonthDay = calculate(MAX(Table2[Date]);FILTER(ALL('Table2');YEAR('Table2'[Date])=YEAR(SELECTEDVALUE(Table1[Date])) && MONTH('Table2'[Date])=MONTH(SELECTEDVALUE(Table1[Date]))))
RETURN
CALCULATE(LASTNONBLANK(Table2[Value];1);Table2[Date]=_lastMonthDay)
