    Hi Anonymous ,

    Please try:

    Previous Value = 
VAR _Cur_Date = 'Sheet1'[Date]
VAR _Pre_Date =
    CALCULATE (
        MAX ( 'Sheet1'[Date] ),
        FILTER ( ALL ( 'Sheet1' ), 'Sheet1'[Date] < _Cur_Date )
    )
VAR _Pre_Value =
    CALCULATE (
        MAX ( 'Sheet1'[Real h_M] ),
        FILTER ( ALL ( 'Sheet1' ), 'Sheet1'[Date] = _Pre_Date )
    )
RETURN
    _Pre_Value

Hi Anonymous ,

The problem is that the date column is not unique. Try to add an index column to the Power Query Eidtor. And use like:

Previous Value =
VAR _Cur_Index = 'Sheet1'[Index]
VAR _Pre_Index =
    CALCULATE (
        MAX ( 'Sheet1'[Index] ),
        FILTER ( ALL ( 'Sheet1' ), 'Sheet1'[Index] < _Cur_Index )
    )
VAR _Pre_Value =
    CALCULATE (
        MAX ( 'Sheet1'[Real h_M] ),
        FILTER ( ALL ( 'Sheet1' ), 'Sheet1'[Index] = _Pre_Index )
    )
RETURN
    _Pre_Value
