    Hi RyanW,

    At first, please note that we can only create measure and calculated column in Power Bi desktop. So I test in Power BI desktop.

    After several days' test, I tried many solutions. Finally, I get the previous day's value. Please create a measure using the formula.

    Prvious-day-value = Var DD=MasterData[Last Run Date]
RETURN 
CALCULATE(MAX(MasterData[CostPerTon]),FILTER(ALLSELECTED(MasterData),MasterData[ProcessDate]=DD))


    Then create a measure to get the increase/decrease percentage.

    Percentage = (MAX(MasterData[CostPerTon])-MasterData[Prvious-day-value])/MAX(MasterData[CostPerTon])



    Please download the attachments to review more details.

    Best Regards,
    Angelia
