Dax measure doesn't return correct total value in all rows

Hi,   Created a measure as below:   Its giving me the correct values at filter context and total as well as shown below:   My expected outcome of this measure should be: total 0.17...

    If I understood correctly now:

    We calculate Rate separately for the rows and for the Total. For each row we have one related utility, for the total we calculate average of averages for all selected utilities:

    VAR IsOneUtility =
    HASONEVALUE ( 'Points'[Utility] )
VAR UtilityAverage =
    IF (
        IsOneUtility,
        CALCULATE (
            [Invoice Unit Rate test 2],
            ALL ( 'Points'[DBName-Point_Id] ),
            'Points'[Utility] = VALUES ( 'Points'[Utility] )
        )
    )
VAR TotalAverage =
    CALCULATE (
        AVERAGEX ( VALUES ( 'Points'[Utility] ), [Invoice Unit Rate test 2] ),
        ALLSELECTED ( 'Points'[DBName-Point_Id] )
    )
VAR Result =
    IF ( IsOneUtility, UtilityAverage, TotalAverage )
RETURN
    Result

    which gives

    Just in case,

    Invoice Unit Rate test 2 =
VAR Cost =
    SUM ( 'Invoice Data'[Cost] )
VAR Units =
    SUM ( 'Invoice Data'[Units] )
VAR div =
    DIVIDE ( ABS ( Cost ), ABS ( Units ), BLANK () )
RETURN
    CALCULATE ( IF ( ISBLANK ( Cost ) || ISBLANK ( Units ), BLANK (), div ) )

I checked only second one.

For DBName-Point_Id you'd like to calculate total for only only two selected points, not for all existing ones. Thus

Invoice Unit Rate test 3 =
CALCULATE (
    [Invoice Unit Rate test 2],
    //    ALL ( Points[DBName-Point_Id] )
    ALLSELECTED ( Points[DBName-Point_Id] )
)

With previous measure you don't need ALL(Points) since Cost and Units are calculated in current row context. If to remove

Invoice Unit Rate test 2 =
VAR Cost = SUM ( 'Invoice Data'[Cost] )
VAR Units = SUM ( 'Invoice Data'[Units] )
VAR div =
    CALCULATE ( DIVIDE ( ABS ( Cost ), ABS ( Units ), BLANK () ) ) //,ALL(Points))
RETURN
    CALCULATE (
        IF ( ISBLANK ( Cost ) || ISBLANK ( Units ), BLANK (), div ),
        ALL ( 'Invoice Data' ),
        ALL ( 'Calendar' ),
        ALL ( Contacts )
    )
//,ALL(Points))

result will be the same.

    Hi SergeiBaklan,

     

    Apologise for the delay in getting back as we were testing this measure at different levels!

    Many thanks for your amazing solution Sir!

     

    What we found from our testing was as below:

    This measure worked amazingly well when we unselect points id and the values are also correct:
    Dax:

     

    Result:

     

    When I unselect points, and select either 1 Utility(gas), this shows correct value 0.36:

     

    When i select electricity utility,dax shows 0.15 for all points which is correct:

    FYR, some examples of point id's that comes under electricity & gas utility as below for your testing purposes:

     

    The Electric Utility contains below points:

    INSE-1000

    INSE-1001

    INSE-1002

    INSE-1003

    INSE-998

    INSE-324

    INSE-41

     

    The gas utility contains points id as below:

    INSE-1214

    INSE-1215

    INSE-1308

     

     

    Now when I select both utility, it shows wrong value(0.16) for all points as shown below based on utility selected:

     

    When i select both utility, dax should show their corresponding average for their points, (i.e)
    The gas utility points should show, 0.36(overall for all gas points) & The Electricity utility points should show 0.15 (overall for all electricity points)

     

    Expected outcome for example point id given above:

    This should work when we unselect/show all point id (0.36 for gas & 0.15 for electricity utility) with only 2 utility selected and expected result as below:

    Thanks in advance!

      Perhaps better to modify test3

      Invoice Unit Rate test 3 =
VAR test2 = [Invoice Unit Rate test 2]
RETURN
CALCULATE (
    test2, // [Invoice Unit Rate test 2],
    ALLSELECTED ( Points[DBName-Point_Id]  )
)

      With that if [Invoice Unit Rate test 2] is blank, [Invoice Unit Rate test 3] is also returns blank and no need to apply filter to visual

        Hi SergeiBaklan 

         

        Thanks for your quick response!

        Apologise for not giving the clear explanation!

         

        My expected result is as below:

        When I select the utility as gas from utility slicer, this measure in below table should show 0.36 for DBName-Poind_id column

        and 0.15 when we select Electricity.

        We don't have to worry about Invoice Unit Rate test 2 measure showing blank values/cells and neither for Invoice Unit Rate test 3.

         

        I am just confused how/whether to modify Invoice Unit Rate test 3 or Invoice Unit Rate test 2 measure in order to achieve above?

         

        Can you please help achieve this result?

        Thanks in advance!

      If to show records when both measures are not blank, you may apply filter to the visual

      which gives
