Maximum Value for measure

[Dunner2020]

Hi there,

I have data which looks like as follow:

Column A,B, C, D are given. 

Column C is the 'Epoch Half Hour Number' which is a unique Id for a half-hour time period. Column E is the calculation that looked at the past 48 half-hour values. I calculated column E using the following measure: 

Past 24 hrs Values=

var Time30Min = MAX('Table'[Epoch Half Hour Number])

Return

SUMX(FILTER(filter(ALL('Table'),'Table'[Epoch Half Hour Number] <= Time30Min && 'Table'[Epoch Half Hour Number] >= Time30Min-47),'Table'[ConsumptionMinutes])/91577

Now I want to calculate another measure that picks the maximum value among 24 values generated by 'Past 24 hrs Values'.  Could anyone guide me on how to do that? Here is the link to the data file:

Hi, @Dunner2020 

It’s my pleasure to answer for you.

Your data seems a bit confusing, but I still try to calculate the maximum(range is 24h)value from your data, First create an index table,then create a measure

Like this:
First create an index table

Measure 2 =
MAXX (
    FILTER (
        ALL ( 'Table' ),
        [Index] >= SELECTEDVALUE ( 'Table'[Index] )
            && [Index]
                <= SELECTEDVALUE ( 'Table'[Index] ) + 23
    ),
    'Table'[Past 24 hrs Values]
)

If it doesn’t solve your problems, please feel free to ask me.

@Dunner2020 , I would advice convert it into datetime and work with that

#datetime(1970,1,1,0,0,0)+#duration(0,0,0,[Epoch]/1000)

In any time you add time like this in dax

Date + time(10,0,0)

@amitchandak , I don't think so that problem in the datetime format. Its is the requirement that's why I could not merge date with time column. I have updated picture and data for more clarification
