PowerBI Rankx Returning only 1 - powerbi

I have a table called Commissions summary that are for sales reps
This table generates a summary row for each sales rep for each month. I want to rank the sales rep only by each month, however my formula is only returning 1's.
The table can be simplified down to this
Sales reps Target Attainment
John, deer 53%
Jane, Joe 160%
Adam, Smith 30%
My goal is to show my table like this
Sales reps Target Attainment Rank
John, deer 53% 2
Jane, Joe 160% 1
Adam, Smith 30% 3
This is the Rankx formula I am using
Ranks =
RANKX (
ALL ( 'Commission Summary' ),
CALCULATE (
SUM ( 'Commission Summary'[Target Attainment] ),
'Commission Summary'[Date] = 10 / 01 / 2019
),
,
DESC
)
As I mentioned earlier, I am only filtering my date to October.
Please help :(

the problem occurs into calculate's filter 'Commission Summary'[Date] = 10 / 01 / 2019. The engine is dividing each number first 10/01 = 10 and 10/2019 = 0.00495 that date doesn't exist in your data returning blank for all values giving as a result a ranking with 1 in all ocurrences (because all are the same blank value).
To avoid this problem use 'Commission Summary'[Date] = DATE(2019,10,1) as filter context. That will return a ranking properly sorted, but you'll have ranked all sales reps including sales reps who had no activity that date (they will be in the bottom of the ranking)
If you want to go a step further i recommend using the following steps:
create a measure first:
Comission Summary Filtered = CALCULATE (
SUM ( 'Commission Summary'[Target Attainment] ),
'Commission Summary'[Date] = DATE(2019,10,1)
Then filter by that measure with the following code:
Rank =
IF (
[Comision Summary Filtered] > 0,
RANKX ( ALL ( 'Commission Summary' ), [Comision Summary Filtered],, DESC, DENSE )
)
With that you'll have a cleaner result. :)

Moving Annual Total with DAX Power BI

I'm trying to calculate MAT (Moving Annual Total) using DAX, but can't realize exactly what I want.
I have the data as below.
What I'm trying to is calculate the total of treatment for each 12 month, like "Jan 21 - Dec 21" which has 'date' from 2020/1/1 to 2020/12/1. i.e. 'A' appears 4 times in that period, so the result will be like below.
Then I'd like to continue this for each latest 12 months, and finally visualize it like below.
I've read that I should use CALCULATE and DATESPERIOD in DAX, can't calculate exactly though. The following code is the one I tried and failed.
Moving Annual Total = CALCULATE(
COUNTA('2017-2022Q1'[idnum]),
DATESINPERIOD('2017-2022Q1'[mat].[Date], LASTDATE('2017-2022Q1'[mat].[Date]), 12, MONTH))
Could someone kindly give me an advise to realize this?
Thanks.

In your dax measure, I recommend you first to create a date table and create a one-to-many relationship with the fact table(your table: '2017-2022Q1') ; then filter the date table in your calculate measure, not the fact table('2017-2022Q1') directly as you did here. You should follow the best practice.
For Example: How to create a date table using dax:
Date =
VAR MinYear = YEAR ( MIN ( '2017-2022Q1'[date] ) )
VAR MaxYear = YEAR ( MAX ( '2017-2022Q1'[date] ) )
RETURN
ADDCOLUMNS (
FILTER (
CALENDARAUTO( ),
AND ( YEAR ( [Date] ) >= MinYear, YEAR ( [Date] ) <= MaxYear )
),
"Calendar Year", "CY " & YEAR ( [Date] ),
"Month Name", FORMAT ( [Date], "mmmm" ),
"Month Number", MONTH ( [Date] )
)
Your final code could be like this:
Moving Annual Total = CALCULATE(
COUNTA('2017-2022Q1'[idnum]),
DATESINPERIOD('Date'[Date], LASTDATE('Date'[Date]), -12, MONTH)
)
if you define the start date using the lastdate() function, then It returns the last date in your filter context. you should also specify the interval as (-12) month to extract all dates within 1 year period.
Hope It helps.

Calculating the cumulative values in Power BI

I have two tables:
user table (contains: user registration data. columns: user_id, create_date)
customer order table (contains: history of orders. columns: user_id, order_date, order_id)
*user and customer aren't the same. when a user registers his first order, he becomes a customer.
For each month of each year, I want the accumulative count of distinct users and the accumulative count of the distinct customers because at last, I want to calculate the ratio of the accumulative count of the distinct customers to the accumulative count of the distinct users for each month.
I don't know how can I calculate the accumulative values and the Ratio that I said, using DAX.
Note that if a customer registers more than one order in a month, I want to count him just once for that month and if he registers a new order in the next months, also I count him in each new month.
Maybe these pictures help you to understand my question better.
-I don't count_of_users and count_of_customers columns in my tables. I should calculate them.
the user table:
user_id

You need a few building blocks for this. Here is the data model I used:
<edit>
I see user_id in the different tables are not the same, in that case you can omit the relationship between the tables and the two relationships from the Calendar table will both be active - with no need to change the relationship semantics in the count_of_customer measure. </edit>
The calendar table is important because we can't rely on one single date column to aggregate data from different tables, so we create a common calendar table with this sample DAX code:
Calendar =
ADDCOLUMNS (
CALENDARAUTO () ,
"Year" , YEAR ( [Date] ) ,
"Month" , FORMAT ( [Date] , "MMM" ) ,
"Month-Year" , FORMAT ( [Date] , "MMM")&"-"&YEAR ( [Date] ) ,
"YearMonthNo" , YEAR ( [Date] ) * 12 + MONTH ( [Date] ) - 1
)
Make sure to sort the Month-Year column by the YearMonthNo column so your tables look nice:
Set your relationships as shown with the active relationship from Calendar to user - if not the measures will not work unless you alter the relationships accordingly in the code! In my data model the inactive relationship is between Calendar and customer order.
Next up are the measures we will use for this. First off we count the users, a simple row count:
count_of_users = COUNTROWS ( user )
Then we count distinct user ids in the order table to count customers, here we need to use the inactive relationship between Calendar and customer order and to do this we have to invoke CALCULATE:
count_of_customers =
CALCULATE (
DISTINCTCOUNT ( 'customer order'[user_id] ) ,
USERELATIONSHIP (
'Calendar'[Date] ,
'customer order'[order_date]
)
)
We can use this measure to count users cumulatively:
cumulative_users =
VAR _maxVisibleDate = MAX ( 'Calendar'[Date] )
RETURN
CALCULATE (
[count_of_users] ,
ALL ( 'Calendar' ) ,
'Calendar'[Date] <= _maxVisibleDate
)
And this measure to count cumulative customers per month:
cumulative_customers =
VAR _maxVisibleDate = MAX ( 'Calendar'[Date] )
RETURN
CALCULATE (
SUMX (
VALUES ( 'Calendar'[YearMonthNo] ) ,
[count_of_customers]
),
ALL ( 'Calendar' ) ,
'Calendar'[Date] <= _maxVisibleDate
)
Lastly we want the ratio of these last cumulative measures:
cumulative_customers/users =
DIVIDE (
[cumulative_customers] ,
[cumulative_users]
)
And here is your result:

What is the purpose of using VALUES or ALL in the first parameter of an iterator function?

I know that only CALCULATE can modify the filter context. However following are 2 example using VALUES and ALL.
Example 1:
Revenue =
SUMX(
Sales,
Sales[Order Quantity] * Sales[Unit Price]
)
Revenue Avg Order =
AVERAGEX(
VALUES('Sales Order'[Sales Order]),
[Revenue]
)
What is the purpose of VALUES in AVERAGEX function? Is this to add an additional filter context?
Example 2:
Product Quantity Rank =
RANKX(
ALL('Product'[Product]),
[Quantity]
)
What is the purpose of using ALL in an iterator function?
Suppose we have a table like this:
ID
Sales Order
Order Quantity
UnitID
Unit Price
1
101
10
4
39.99
2
101
15
3
24.99
3
102
5
2
15.99
4
103
5
1
14.99
5
103
10
3
24.99
Since the Sales Order column has duplicates,
Revenue Avg Order = AVERAGEX ( VALUES ( Sales[Sales Order] ), [Revenue] )
gives a different result than
Revenue Avg ID = AVERAGEX ( Sales, [Revenue] )
since the first averages over the three Sales Order values whereas the second averages over the five ID rows.
Using DISTINCT instead of VALUES would work too.
Using ALL is instead of VALUES gives the same total but ignores the local filter context from the table visual:
Revenue Avg All = AVERAGEX ( ALL ( Sales[Sales Order] ), [Revenue] )
In this context, ALL is acting as a table function that returns all of the distinct values of the column specified ignoring filter context.

Calculate price based on distinct count

I am having trouble working out a measure (Revenue) in power bi.
I have a measure which is basically counting distinct values in a table (table 1). From this column I want to multiply the distinct count to get the total price (prices are in another table).
See below for an example
Table 1
Product DistinctCount Revenue (Measure I am trying to Calculate)
A 15 45.00
B 30 60.00
Prices Table
Product Price
A 3.00
B 2.00
At the moment the Revenue is calculating based on COUNT and not DISTINCTCOUNT.
Any help would be much appreciated.
thanks!
Measures, Calculated Columns, Google
I am assuming you have a relationship set up between these two tables on [Product]. If this is the case you can do something like this to create a calculated column:
Revenue =
CALCULATE (
SUMX ( 'Table 1', 'Table 1'[DistinctCount] * RELATED ( 'Prices Table'[Price] ) )
)
If you are trying to create a table visual try the DAX below, where ID is just a transaction ID for each product in your 'Table 1':
Revenue =
VAR DistinctCountOfProductTransactions =
CALCULATE ( DISTINCTCOUNT ( 'Table'[Id] ) )
VAR Result =
CALCULATE (
DistinctCountOfProductTransactions * SUM ( Prices[Price] ),
TREATAS ( VALUES ( 'Table'[Product] ), Prices[Product] )
)
RETURN
Result

Power BI Rolling Total Previous Month DAX

I am working in POWER BI and trying to calculate a DAX expression for the rolling total of the previous month. I have a filter where I select a certain month, I would like to calculate the rolling total for the previous month.
Below is the calculation that works perfectly to calculate the rolling total for the selected date range.
How can I calculate the previous months rolling total?
Rolling_Total_Current_Month = CALCULATE(
SUM(SalesInvoice[Sales])
,FILTER(ALLSELECTED(SalesInvoice), (SalesInvoice[Date]) <= MAX(SalesInvoice[Date])))
Here is a sample of my data, I have sales per day, for multiple categories, (in fact i have a couple more columns of details but this is simplified)
Date Day Amount Category
1/1/2016 1 100 A
1/1/2016 1 120 B
1/1/2016 1 90 C
1/2/2016 2 500 A
1/2/2016 2 321 B
1/2/2016 2 143 C
So far I have come up with an equation to solve the rolling total, but when I try to slice is and view the rolling total of a single category it does not work for the previous month. I just keeps the original rolling total for the previous month.
Here is the equation for the rolling total previous month that works. But does not recalculate a rolling total for the previous month once sliced based on category.
PREVIOUS_MONTH_ROLLING_TOTAL =
CALCULATE(
[Current Sales]
,FILTER(
ALL( Orders )
,Orders[MonthNumber] = MAX( Orders[MonthNumber] ) - 1
&& Orders[Day] <= MAX( Orders[Day] )
)
)
I have solved how to get the previous months rolling total.
You must do three things. First create a Month Number column in your data sheet (this is used as an integer to subtract 1 month from). You must also create a days column as well.
Then create a measure for Current Sales or whatever your value is.
Create a measure for the current month sales
Current Sales = SUM(Orders[Amount])
Then this equation.
PREVIOUS_MONTH_ROLLING_TOTAL =
CALCULATE(
[Current Sales]
,FILTER(
ALL( Orders )
,Orders[MonthNumber] = MAX( Orders[MonthNumber] ) - 1
&& Orders[Day] <= MAX( Orders[Day] )
)
)
The Idea of this equation is to be able to display the previous months rolling total on a chart with the X axis as "DAY" (so 1-31) Then you can view the current month, previous month, same period last year all on the same chart or table.
Try something along these lines:
Rolling_Total_Previous_Month =
VAR CurrentMonth = MAX(SalesInvoice[Date])
VAR PreviousMonth = EOMONTH(CurrentMonth,-1)
RETURN CALCULATE(SUM(SalesInvoice[Sales]), SalesInvoice[Date] <= PreviousMonth)
To start of, I have a data like this in a table called as Orders-
Date Amount
12/12/2017 100
12/12/2017 200
12/12/2017 300
1/1/2018 400
1/1/2018 500
I first create a calculated column called as Year & Month by using the formula:-
Year = YEAR(Orders[Date])
Month = FORMAT(Orders[Date],"mmmm")
Then I create a column called as Month Number which will be helpful for sorting when more than one year is involved in the table and as well as to Identify the Previous Months.
MonthNumber = DATEDIFF(Min(Orders[Date]),Orders[Date],MONTH)
Current Month Sales can be a measure or a Calculated column. Qn the Question, you had your answer for current month sales via a calculated column and if you want to go for a measure then something like this would work on a summary table.
Current Month Sales = SUm(Orders[Amount])
I would also create a column called as Key:-
Key = Orders[MonthNumber] & Orders[Category]
Now, for the Previous Month Sales, I would create a measure that looks for selected MonthNumber that we created.
Previous Month Sales =
Var SelectedCategory = SELECTEDVALUE(Orders[Category])
Var SelectedMonthNumberr = SELECTEDVALUE(Orders[MonthNumber]) - 1
Var ReqKey = SelectedMonthNumberr & SelectedCategory
Return
IF(ISBLANK(SelectedCategory) <> True(),
CALCULATE(SUM(Orders[Amount]),FILTER(ALL(Orders), Orders[Key] = ReqKey)),
CALCULATE(SUM(Orders[Amount]),FILTER(ALL(Orders), Orders[MonthNumber] = SelectedMonthNumberr)))
or to your Measure
PREVIOUS_MONTH_ROLLING_TOTAL =
CALCULATE(
[Current Sales]
,FILTER(
ALL( Orders )
,Orders[MonthNumber] = MAX( Orders[MonthNumber] ) - 1
&& Orders[Day] <= MAX( Orders[Day] )
)
)
You can just add another filtering item as && Orders[Category] = SELECTEDVALUE(Orders[Category]) but won't work when you don't have any categories selected or on a table or visual which doesn't have categories. So, you would need to define an if else logic here as I have quoted on my measure formula.
Do let me know, if this helps or not.
