Im looking for a formula that can calculate linear depreciation (Capex divided years).   Are there any who have tips about making formula in DAX that can manage this?

    based on the originals tables you posted this should work, I'm assuming second table is named Parameter

    Depreciation =
VAR License = Inputtabel[License]
VAR CurrentYear = Inputtabel[Year]
VAR NrOfDeprYears =
    RELATED ( Parameter[Year depreciation] )
VAR CapexToDate =
    ADDCOLUMNS (
        FILTER (
            Inputtabel,
            Inputtabel[License] = License
                && Inputtabel[Year] <= CurrentYear
                && NOT ( ISBLANK ( Inputtabel[Capex] ) )
        ),
        "NrOfYearsDepr", RELATED ( Parameter[Year depreciation] )
    )
VAR FullCapexPerYear =
    FILTER (
        GENERATE (
            CapexToDate,
            GENERATESERIES (
                [Year],
                [Year] + RELATED ( Parameter[Year depreciation] )
                    - 1,
                1
            )
        ),
        [Value] = CurrentYear
    )
RETURN
    SUMX ( FullCapexPerYear, [Capex] / [NrOfYearsDepr] )

Thank you very much. I have to spend some time to learn this formula but it look very interesting.
