Calculated table dynamically change from new data

[Jānis]

Hello,

I have data (in table):

I need to calculate and show, what is average employees age at the end of each month in period (for example in period 2017-09 - 2017-12). In example at the end of december (47+27+19)/3. I will show it with Line chart and need to calculate age for every employee at the end of each month in active period.

How could I calculate those data? I assume that I need to calculate table...

Or maybe there is other solution.

I will appreciate any help.

@Jānis,

Create a date table to return the last day of each month.

Create a date table

Date = CALENDAR(DATE(2015,1,1),DATE(2017,12,31))

Create a column to get the last day of each month
LastDay = ENDOFMONTH('Date'[Date])

Create another table
LastDayofMonth = SUMMARIZE('Date','Date'[LastDay])

Create a column to get average age.
AverageAge =
DATEDIFF (
    CALCULATE (
        AVERAGE ( Table2[BirthDate] ),
        FILTER (
            Table2,
            OR (
                ISBLANK ( Table2[InactiveDate] ),
                Table2[InactiveDate] > 'LastDayofMonth'[LastDay]
            )
        )
    ),
    'LastDayofMonth'[LastDay],
    YEAR
)

I needed to make some changes, but in generally it is what I needed.

Thank you, @v-caliao-msft!

Almost working. I'm still cheking solution (new with DAX).

I found, that I need one more filter - I need to include only active employees, so I need to filter from "Employment Start Date" too, but not sure - is it correct.

AverageAge =
DATEDIFF (
    CALCULATE (
        AVERAGE ( Table2[BirthDate] ),

        FILTER (

            Table2, Table2[Employment Start Date] < 'LastDayofMonth'[LastDay]

            ),
        FILTER (
            Table2,
            OR (
                ISBLANK ( Table2[InactiveDate] ),
                Table2[InactiveDate] > 'LastDayofMonth'[LastDay]
            )
        )
    ),
    'LastDayofMonth'[LastDay],
    YEAR
)
