Compare Data within the same table

Anonymous

Thanks for the response! 

I tried adding the "Hostname" as well, the remaining issue is that the Totals are not correct. I have found the issue; The formula for "Diff MOM" does not add a variance per hostname level when drilling down, which means that the Total is incorrect. See attached pictures.

At first I thought it had to do with "Allselected" and changed it to use the "All" formula, but that didnt do it. 

Any ideas for this last step? 

Thanks again, I really do appreciate the help!

Hi tonijj,

It seems like I only add 'host name' filter on previous total variable,now I add it to current total variable, maybe you can try ot use following formula if it fix the issue.

MOM Diff =
VAR currDate =
    MAX ( DateTable[DateKey] )
VAR currTotal =
    CALCULATE (
        SUM ( DetailedVolumes[Volume] ),
        FILTER (
            ALLSELECTED ( DetailedVolumes ),
            MONTH ( [DateKey] ) = MONTH ( currDate )
        ),
        VALUES ( Services[SIN] ),
        VALUES ( Service[Host Name] )
    )
VAR prevTotal =
    CALCULATE (
        SUM ( DetailedVolumes[Volume] ),
        FILTER (
            ALLSELECTED ( DetailedVolumes ),
            MONTH ( [DateKey] )
                = MONTH ( currDate ) - 1
        ),
        VALUES ( Services[SIN] ),
        VALUES ( Service[Host Name] )
    )
RETURN
    IF ( prevtotal <> BLANK (), currTotal - prevTotal )

BTW, 'all' function will ignore other filter effects, so I use 'allselected' function to instead.(it can also break current row contents filter but not ignore other filters)

Hi, 

I actually did try to add that line to the formula, but it didnt work. Well, except for that the "hostname" is in the table "Detailedvolume". In any case, I get the same result, it leaves the "MOM Diff" blank even though there is a difference, but only on hostname level. 

If the formula would calculate on that level as well Im pretty sure the Totals would be fine. Any other suggestions?

Ps. Of course youre right about the "ALL" function, thanks for the explanation, think I was just too tired when I tried that out last week :) Appreciate the explanation!

Hi tonijj,

Yes, measure with specific filters has some trouble to calculate on total level, maybe you can take a look at following blog which told about hierarchy level handling.
