DAX Related() with Many to Many relationship in Power BI - sorting

I have a model where we need to sort the legend column based on Total sum of a column
My Line graph uses Quarter and Total in the axis.Category is used as Legend.Graph is sorted by Quarter in Ascending Order.
Now i want the Tool tip to be sorted by Total Alerts .Tool Tip shows Category value and Total .
For each quarter category value may be different
For Eg :
Q1:
Bus : 1
Car : 2
Q4:
Bus : 7
Car 6
So based on this my Tool tip should be sorted in Descending order automatically.When i Tried Related () i am able to sort based on category but based on quarter level i am not able to sort

Wrong sorting while using Query function

I've been trying to do a report about the quantity of breakdonws of products in our company. The problem is that the QUERY function is operating as normal, but the sorting order is well - a bit strange.
The data I'm trying to sort are as follows (quantities are blacked out since I cannot share those informations):
Raw data
First column - name of the product, second, it's EAN code, third, breakdown rate for last year, last column - average breakdown rate. "b/d" means "brak danych" or no data.
What I want to achieve is to get the end table with values sorted by average breakdown rate.
My query is as follows:
=query(Robocze!A2:D;"select A where A is not null and NOT D contains 'b/d' order by D desc")
Final result
As You can see, we have descending order, but there are strange artifacts - like the 33.33% after 4,00% and before 3,92%.
Why is that!?
try:
=INDEX(LAMBDA(x; SORT(x; INDEX(x;; 4)*1; 0))
(QUERY(Robocze!A2:D; "where A is not null and NOT D contains 'b/d'"; 0));; 4)

Validation list with multiple criterias

I sort out my problem but I am wondering if an easier way doing it doesn't exist.
With the function onEdit(), I am creating from a first validation list, a second validation list in the next cell.
So, the code below is just for information.
var validationRange = data.getRange(3, myIndex, data.getLastRow());
var validationRule = SpreadsheetApp.newDataValidation().requireValueInRange(validationRange).build();
activeCell.offset(0, 1).setDataValidation(validationRule);
In this validation list, I need to select a name, taking into account two additionnal criterias :
Name
Times
LastWeek
Patrick
2
W22
Rachel
5
W15
Claire
3
W14
Olivier
4
W16
Hélene
2
W20
It means that "Patrick" attended "2" times and last time was in week "W22".
I need to take into account these two criterias to select one of the attendee
I.E. : I try to let each person participate the same number of times but not every week (the oldest first)
So, I created a validation list with a "sorted key" that allows me to first see the person who has attended less and for longer.
Key Sorted
#02W20#Hélene
#02W22#Patrick
#03W14#Claire
#04W16#Olivier
#05W15#Rachel
This validation list is used 3, 5, 7 times in the same sheet because person can do different activities. Then, when all person are selected another script removes the values between # to keep only the name in the final sheet.
So, the question is :
could we create a validation list with multiple columns, the selected value being only the value of the first column.
I guess many users would enjoy it when we glance at questions about multiple criteras selection lists.
Thanks

Power Query (M language) 50 day moving Average

I have a list of products and would like to get a 50 day simple moving average of its volume using Power Query (M).
The table is sorted by product name and date. I add a custom column and applied the code below.
if [date] >= #date(2018,1,29)
then List.Average(List.Range(Source[Volume],[Volume]-1,-50))
else ""
Since it is already sorted by date and name, an if statement was applied with a date as criteria/filter. However, an error occurs that says
'Volume' column not found in the table.
I expect to have an added column in the power query with volume 50 day moving average per product. the calculation to be done if date is greater than or equal Jan 29, 2018.
We don't know what your columns are, but assuming you have [product], [date] and [volume] in Source, this would average the last 50 days of [volume] for the identical [product] based on each [date], and place in a new column
AvgAmountAdded = Table.AddColumn(Source, "AverageAmount", (i) => List.Average(Table.SelectRows(Source, each ([product] = i[product] and [date]<=i[date] and [date]>=Date.AddDays(i[date],-50)))[volume]), type number)
Finally! found a solution.
First, apply Index by product see this post for further details
Then index again without criteria (index all rows)
Then, apply below code
= Table.AddColumn(#"Previous Step", "Volume SMA(50)", each if [Index_byProduct] >= 50 then List.Average(List.Range(#"Previous Step"[Volume], ([Index_All]-50),50)) else 0),
For large dataset, Table.Buffer function is recommended after index-expand step to improve PQ calculation speed

olap4J - calculations on member grouping

I'm trying to write an olap4j (Mondrian) query that will group the rows by ranges.
Assume we have counts of cards per child and the children ages.
i want to sum the cards amount by age ranges, so i will have counts for ages 0-5,5-10,10-15 and so on.
Is this can be done with olap4j?
You need to define calculated members for that:
With member [Age].[0-4] as [Age].[0]:[Age].[4]
member [Age].[5-9] as [Age].[5]:[Age].[9]
etc.
Alternatively, you may want to re-design your dimension table. I'm guessing you have age as a degenerate dimension in the fact table. I suggest creating a separate dimension dim_age with a structure like this:
age_id, age, age_group
0, null, null
1, 0, 0-4
2, 1, 0-4
(...)
Then it's easy to define a first level on the dimension based on the age_group.

Complicated Cube Query

I'm working on a fairly complicated view, which calculates the total cost of a guest's stayed based on data pulled from four different tables. The output however is not exactly what I want. My code is
CREATE OR REPLACE VIEW Price AS
SELECT UNIQUE
Booking.Booking_ID AS "Booking",
Booking.GuestID AS "Guest ID",
Room.Room_Price*(Booking.CheckOutDate-Booking.CheckInDate) AS "Room Price",
Add_Ons.Price AS "Add ons Price",
Room.Room_Price*(Booking.CheckOutDate-Booking.CheckInDate) + (Add_Ons.Price) AS "Total Price"
FROM Booking JOIN Room ON Room.Room_Num = Booking.Room_Num
JOIN Booking_Add_Ons ON Booking.Booking_ID = Booking_Add_Ons.Booking_ID
JOIN Add_ons ON Booking_Add_Ons.Add_On_ID = Add_Ons.Add_On_ID
ORDER BY Booking.Booking_ID;
Now, I'm trying to get this to return the total cost of all Addons, plus the cost of the hotel rooms as the total price, however it is returning the cost of the rooms + each of the addons on separate lines. As follows:
My question is, is it possible to use something like CUBE, or SUM to add up the rows, so that there is only one entry for each of the Bookings with the total price of all add-ons accounted for?
