Need Help with date difference between values within a column

[Dyke211]

HI Guys, can anyone give me a good dax measure of calculated column that shows different in the number of days between reported events within a single column such that if i slice based on Assettype, i can see the current date different between the group of asset class in a dynamic way. That means Machine A will show me the number in days of date different between only its class type ansd Machine B will show me the date difference row by row between its own class....

What i haveWHat i want

I would like to slice by Machine type such that the days different starts from here and show me the difference between this similar type

Hi @Dyke211 

please try

Number of Days Diff. =
VAR CurrentDate = 'Table'[ReportedEvent]
VAR CurrentTypeDates =
    CALCULATETABLE (
        VALUES ( 'Table'[ReportedEvent] ),
        ALLEXCEPT ( 'Table', 'Table'[AssetType] )
    )
VAR previousDate =
    MAXX (
        FILTER ( CurrentTypeDates, 'Table'[ReportedEvent] < CurrentDate ),
        'Table'[ReportedEvent]
    )
RETURN

    DATEDIFF ( COALESCE ( previousDate, CurrentDate ), CurrentDate, DAY )
