    Hi ,
    Can you try to change the datediff to minutes and change the less than condition.
    Thanks.

    JUST PERFECT!!!

     

    started = VAR v_LagPart = CALCULATE( MAX( Data[part] ), FILTER( Data, Data[part] = EARLIER( Data[part] ) && Data[installdate] < EARLIER( Data[installdate] ) ) ) VAR v_LagDate = CALCULATE( MAX( Data[installdate] ), FILTER( Data, Data[part] = EARLIER( Data[part] ) && Data[installdate] < EARLIER( Data[installdate] ) ) ) RETURN IF( Data[part] = v_LagPart && ( DATEDIFF( v_LagDate, Data[installdate], MINUTE ) < 1440 ), "No", "Yes" )

Wow, it is very, very close to it!!!

Though I still find only 5 instances where the response should be "No", see two examples highlighted.

One thing I noticed is that on those cases the "installdate" difference is very close to 24 hours, somthing like 23.5 or higher.
