## Using MAXX in a hierarchy

Hi!

So I have a problem with calculating the max values correctly on group level, and I can't wrap my head around it. Have actually spent days, and would really love some input

I have groups, that consist of several units. And in those unitsvalue (numerator/denominator) is calculated.
This is my model:

The challenge is in the measure MaxValue, that is:

MaxValue =
CALCULATE(
MAXX(
VALUES('DIMDATE (2)'[WeekNumber]),
'Values'[value]))

What I want:
For each group I want to find the week that gives the highest value, and for one week only the date with highest value should be includedIt works as desired for Group2Week 34 gives the highest value in this case, so on group level the MaxValue is (4+3)/(10+10) = 0.35

But when there is more than one date in a week, it uses the average for this week instead of only including the single date with the highest value. So Group 1 shows wrong MaxValue.

The value for Group1 should be (3+3)/(20+20)=0.15

Hi @Anonymous,

In this case you need to go to you lowest level of granularity that is the day redo your measure to:

``````MaxValue day =
CALCULATE(
MAXX(
VALUES('DIMDATE (2)'[Date]),
'Values'[value]))``````

Has you can see the result is correct at the day level:

Hi!
However, this solution will only take the values from the one single date with the highest value.
It should use the highest value for every single unit, not only the one highest value

Hi @Anonymous ,

Can you please explain a little bit better how the calculation is done? Not sure if I understood how you are picking up the values.

When you refer that "The value for Group1 should be (3+3)/(20+20)=0.15"

Can you tell wich lines you are picking up on each of the values.

Yes, I'll try to formulate it better!

I want to find the max values for each unit for each week.

In group 1 for units
Unit A Week 34: num=1, denom=10 (17.08)
Unit A Week 35: num=3, denom=20 (24.08)
-(because this gives a higher value than 23.08.2022 which is num=2, denom=20)

Unit B Week 34: num=0, denom=10 (17.08)
Unit B Week 35: num=3, denom=20 (24.08)

In group 1 for the group:
Values here are from the step above
Week 34: num=1+0, denom=10+10 --> value = 1/20
Week 35: num=3+3, denom=20+20 --> value = 3/20

This means week 35 is the largest, and the displayed value should be 0.15 for group 1.
I see that your caluclation gives the same, but that's just because of my unfortunate choice of values

Did it make any sense?
Thank you so much for taking the time to look at this!

Btw, It's not so important what is displayed in MaxValue on unit level, as long as the value at Group level is correct 🙂
