Add column with same calculation

[Snip]

neeHi

I hope some body can help me! 

I have 2 tables, one with dates and one with values, they are connected. 

I then what to calculate the sum of the last month and insert the value in a column and same value for every row. 

So my data could look something like:

Date	Value
2020-01-01	5
2020-01-10	8
2020-01-15	88
2020-01-20	9
2020-01-30	55
2020-02-08	654
2020-02-18	85
2020-02-25	1

The sum of the last month is 740 I would then like to have a new column there is just 740 for every row. Like below

Date	Value	Total
2020-01-01	5	740
2020-01-10	8	740
2020-01-15	88	740
2020-01-20	9	740
2020-01-30	55	740
2020-02-08	654	740
2020-02-18	85	740
2020-02-25	1	740

Hope some body can help me 🙂

@Snip , Create a new column as

Column = sumx(FILTER('Table',EOMONTH([date],0) =EOMONTH(max([Date]),0)),[Value])

Hi @Snip ,

Please try this:

Measure =
VAR mon_ =
    CALCULATE ( MAX ( 'Table'[Date] ), ALLSELECTED ( 'Table' ) )
RETURN
    CALCULATE (
        SUM ( 'Table'[Value] ),
        FILTER (
            ALL ( 'Date' ),
            'Date'[Month] = MONTH ( mon_ )
                && MAX ( 'Table'[Value] ) <> BLANK ()
        )
    )
