Create a custom column that generates rows for every year between two dates

[Anonymous]

I have tried to create a custom column that generates a row for every year in between two dates. I have applied a query that produces this by the day but I need year instead.

Here is the query for days that I need to adapt for years:

List.Dates([EmploymentCommencedDate], Duration.Days ([EmploymentTerminatedDate]-[Column1.EmploymentCommencedDate]), #duration (1,0,0,0))

Here is an example of my table before:

EmployeeID	EmploymentCommencedDate	EmploymentTerminatedDate
400	12/3/2017	9/30/2020
401	10/3/2019	1/5/2021

Here is what I want to have:

EmployeeID	EmploymentCommencedDate	EmploymentTerminatedDate	YearEnd
400	12/3/2017	9/30/2020	12/31/2017
400	12/3/2017	9/30/2020	12/31/2018
400	12/3/2017	9/30/2020	12/31/2019
400	12/3/2017	9/30/2020	12/31/2020
401	10/3/2019	1/5/2021	12/31/2019
401	10/3/2019	1/5/2021	12/31/2020
401	10/3/2019	1/5/2021	12/31/2021

Once I have this, I will calculate the duration of time of employment in years (Tenure) but the difference of the YearEndDate - EmploymentCommencedDate

EmployeeID	EmploymentCommencedDate	EmploymentTerminatedDate	YearEndDate	Tenure
400	12/3/2017	9/30/2020	12/31/2017	0
400	12/3/2017	9/30/2020	12/31/2018	1
400	12/3/2017	9/30/2020	12/31/2019	2
400	12/3/2017	9/30/2020	12/31/2020	3
401	10/3/2019	1/5/2021	12/31/2019	0
401	10/3/2019	1/5/2021	12/31/2020	1
401	10/3/2019	1/5/2021	12/31/2021	2

Hi,

Please check the below picture and the attached pbix file.

It is for creating a new table by DAX.

New table create by DAX = 
VAR _employeetable = Employee
VAR _mindateyear =
    YEAR ( MIN ( Employee[EmploymentCommencedDate] ) )
VAR _maxdateyear =
    YEAR ( MAX ( Employee[EmploymentTerminatedDate] ) )
VAR _calendartable =
    CALENDAR ( DATE ( _mindateyear, 1, 1 ), DATE ( _maxdateyear, 12, 31 ) )
VAR _endofyear =
    SUMMARIZE (
        ADDCOLUMNS (
            _calendartable,
            "@yearenddate",
                MAXX (
                    FILTER ( _calendartable, YEAR ( [Date] ) = YEAR ( EARLIER ( [Date] ) ) ),
                    [Date]
                )
        ),
        [@yearenddate]
    )
RETURN
    GENERATE (
        _employeetable,
        FILTER (
            _endofyear,
            YEAR ( [@yearenddate] ) >= YEAR ( Employee[EmploymentCommencedDate] )
                && YEAR ( [@yearenddate] ) <= YEAR ( Employee[EmploymentTerminatedDate] )
        )
    )
