How to combine SUMMARIZE table with the Original Table?

Please see attached screenshot. I have an OG table (left). I then can use a SUMMARIZE function to create the middle table, which shows the AvgNumHours. I would like to combine the results to my OG table. My goal is to get to the table on the right exactly as shown with the blank spaces too. Is there a function or expression I can use to get to that table? Thanks!

Hi, 

Please check the below DAX formula and the attached pbix file to create a new column.

 

AvgNumHours CC =
VAR currentstartdate = Data[StartDate]
VAR currentsource = Data[Source]
VAR currentactivityname = Data[ActivityName]
VAR startingrow =
    FILTER (
        GROUPBY (
            Data,
            Data[StartDate],
            Data[Source],
            Data[ActivityName],
            "@startingrowNumHours", MINX ( CURRENTGROUP (), Data[NumHours] )
        ),
        Data[StartDate] = currentstartdate
            && Data[Source] = currentsource
            && Data[ActivityName] = currentactivityname
    )
RETURN
    IF (
        Data[NumHours] = MINX ( startingrow, [@startingrowNumHours] ),
        AVERAGEX (
            FILTER (
                Data,
                Data[StartDate] = currentstartdate
                    && Data[Source] = currentsource
                    && Data[ActivityName] = currentactivityname
            ),
            Data[NumHours]
        )
    )

@Anonymous you can use this code for the calculated column:

 

tbl[AvgNumHours] =
VAR _startdate = tbl[StartDate]
VAR _source = tbl[Source]
VAR _activity_name = tbl[ActivityName]
VAR _min_value = CALCULATE(MIN (tbl[NumHours]), REMOVEFILTERS(tbl[NumHours]))
VAR _result = 
	CALCULATE(
		AVERAGE(tbl[NumHours]),
		REMOVEFILTERS(tbl[NumHours])
	)
RETURN
	IF( tbl[NumHours] = _min_value, _result)

Thanks for your valuable input...This ALMOST works. The issue is in the RESULT section when you use the MINX function that grouping can have duplicate MINIMUM because the [NumHours] can have 2 same MINIMUM values.

 

Is there a way to use another function that only results in 1 assignment in the grouping? I believe MINX and MAXX will not work if the [NumHours] are not unique.

I think I can add an INDEX column to find the MINX and then apply to [NumHours]...but if you know of an alternate function please let me know...Thanks.

@Anonymous , Add an index column in Power Query first

Index Column: https://youtu.be/NS4esnCDqVw

 

Then you can create a new column like.I do not think you need even a second table

 

New column =

var _ind = minx(filter(Table, [Date] =earlier([Date]) && [Source] =earlier([Source]) && [ActivityName] =earlier([ActivityName]) ), [Index])
var _avg = AverageX(filter(Table, [Date] =earlier([Date]) && [Source] =earlier([Source]) && [ActivityName] =earlier([ActivityName]) ), [NumHours])
return
if([Index] =_ind, _avg , blank())
