    Hi nasbkrv ,

     

    Please add an Index column in Power Query Editor first. And then, create calculated columns like so:

    From =
CALCULATE (
    SUM ( 'Table'[Metric] ),
    FILTER (
        ALLEXCEPT ( 'Table', 'Table'[ID] ),
        'Table'[Index] < EARLIER ( 'Table'[Index] )
    )
) + 0

    To =
'Table'[From] + 'Table'[Metric]

     

    Best Regards,

    Icey

nasbkrv - Not 100% sure I understand but seems like you need an index column or something similar to identify previous rows. See my article on Mean Time Between Failure (MTBF) which uses EARLIER: http://community.powerbi.com/t5/Community-Blog/Mean-Time-Between-Failure-MTBF-and-Power-BI/ba-p/339586
