Active users on a given date in a Month in Power BI - powerbi

I am working to get cumulative distinct count of uids on daily basis. My dataset consists dates and UserIDs active on that date. Example : Say there are 2 uids (235,2354) appeared on date 2022-01-01 and they also appeared on next day with new uid 125 (235,2354,125) on 2022-01-02 At this point i want store cumulative count to be 3 not 5 as (user id 235 and 2354 already appeared on past day ).
My Sample Data looks like as follows:

and my output should look as follows:

Here's one way that seems to work, using your linked Excel sheet as the data source.
Create a new table:
Table 2 = DISTINCT('Table'[Date])
Add the columns:
MAU = CALCULATE(
DISTINCTCOUNT('Table'[User ID]),
'Table'[Date] <= EARLIER('Table 2'[Date]))
DAU = CALCULATE(DISTINCTCOUNT('Table'[User ID]),
'Table'[Date] = EARLIER('Table 2'[Date]))
Result from your Excel data

Distinct count of values based on date in DAX

I have a table like shown below:
ID
Date
Asset
Location
145
7/29/22
A
Market
145
7/30/22
A
Warehouse
145
7/29/22
B
Market
145
7/29/22
C
Truck
150
7/30/22
B
Market
145
7/29/22
D
Market
145
7/30/22
A
Market
What I am trying to accomplish is to get a distinct count of IDs for each date with a location filter as well. So I would want a count of ID based on the slicer selected Date of 7/29/22 AND 7/30/22 for the Market Location. The desired result is 2 for the selected dates from the date slicer which directly corresponds to the date column in the table.
I was trying to use this DAX formula and wasn't getting anywhere....
IDsMarket =
CALCULATE (
DISTINCTCOUNT ( 'Products'[ID] ),
ALL ( 'Products' )
)
I have a measure dropped onto a card. I should have specified that. My apologies. I need 1 measure to show me the combined count for the two days selected.
I tried this with countrows as well but of course the result wasn't distinct... Any help would be greatly appreciated!!
The formula you're looking for is
IDsMarket =
CALCULATE(
DISTINCTCOUNT('Products'[ID]),
'Products'[Location] = "Market"
)
The resulting Table will look like this
But if you put the measure on a Card visual, you'll get
So in DAX the same measure can yield 1000 different values - depending on the filter context.
I created a conditional column in Power Query and combined the ID with the "day" number from the date column which allowed me to then do a distinct count on that combined custom column which produced to correct answer. Sorry for all the confusion. One of those days.

Power BI - Filtering model on latest version of all attributes of all dimensions through DAX

I have a model that's comprised of multiple tables containing, for every ID, multiple rows with a valid_from and valid_to dates.
This model has one table in that is linked to every other table (a table working as both a fact and a dimension).
This fact has bi-directional cross filtering with the other tables.
I also have a date dimension that is not linked to any other table.
I want to be able to calculate the sum of a column in this table in the following way:
If a date range is selected, I want to get the sum of the latest value per ID from the fact able that is before the max selected date from the date dimension.
If no date is selected, I want to get the sum of the current version of the value per ID.
This comes down to selecting the latest value per ID filtered on the dates.
Because of the nature of the model (bi-directional with the fact/dimension table), I want to have the latest version of any attribute from any dimension selected in the visual.
Here's an data example and the desired outcome:
fact/dimension table:
ID
Valid_from
Valid_to
Amount
SK_DIM1
SK_DIM2
1
01-01-2020
05-12-2021
50
1234
6787
1
05-13-2021
07-31-2021
100
1235
6787
1
08-01-2021
12-25-2021
100
1236
6787

12-26-2021
12-31-2021
200
1236
6787
1
01-01-2022
12-31-9999
200
1236
6788
Dimension 1:
ID
SK
Valid_from
Valid_to
Name
1
1234
10-20-2019
06-01-2021
Name 1
1
1235
06-02-2021
07-31-2021
Name 2
1
1236
08-01-2021
12-31-9999
Name 3
Dimension 2:
ID
SK
Valid_from
Valid_to
Name
1
6787
10-20-2019
12-31-2021
Name 1
1
6788
01-01-2022
12-31-9999
Name 2
My measure is supposed to do the following:
If no date is selected than the result will be a matrix like the following:
Dim 1 Name
Dim 2 Name
Amount Measure
Name 3
Name 2
200
If July 2021 is selected than the result will be a matrix like the following:
Dim 1 Name
Dim 2 Name
Amount Measure
Name 2
Name 1
100
So the idea here is that the measure would filter the fact table on the latest valid value in the selected date range, and then the bi-directional relationships will filter the dimensions to get the corresponding version to that row with the max validity (last valid row) in the selected range date.
I have tried to do the following two DAX codes but it's not working:
Solution 1: With this solution, filtering on other dimensions work and I get the last version in the selected date range for all attributes of all used dimensions. But the problem here is that the max valid from is not calculated per ID, so I only get the max valid from overall.
Amount Measure=
VAR _maxSelectedDate = MAX(Dates[Dates])
VAR _minSelectedDate = MIN(Dates[Dates])
VAR _maxValidFrom =
CALCULATE(
MAX(fact[valid_from]),
DATESBETWEEN(fact[valid_from], _minSelectedDate, _maxSelectedDate)
|| DATESBETWEEN(fact[valid_to], _minSelectedDate, _maxSelectedDate)
)
RETURN
CALCULATE(
SUM(fact[Amount]),
fact[valid_from] = _maxValidFrom
)
Solution 2: With this solution, I do get the right max valid from per ID and the resulting number is correct, but for some reason, when I use other attributes from the dimensions, it duplicates the amount for every version of that attribute. The bi-directional filtering does not work anymore with Solution 2.
Amount Measure=
VAR _maxSelectedDate = MAX(Dates[Dates])
VAR _minSelectedDate = MIN(Dates[Dates])
VAR _maxValidFromPerID =
SUMMARIZE(
FILTER(
fact,
DATESBETWEEN(fact[valid_from], _minSelectedDate, _maxSelectedDate)
|| DATESBETWEEN(fact[valid_to], _minSelectedDate, _maxSelectedDate)
),
fact[ID],
"maxValidFrom",
MAX(fact[valid_from])
)
RETURN
CALCULATE(
SUM(fact[Amount]),
TREATAS(
_maxValidFromPerID,
fact[ID],
fact[valid_from]
)
)
So if somebody can explain why the bi-directional filtering doesn't work anymore that will be great, and also, more importantly, if you have any solution to have both the latest value per ID and still keep filtering on other attributes, that would be great!
Sorry for the long post, but I thought it's best to give all the details for a complete understanding of my issue, this has been picking my brain since few days now and I'm sure I'm missing something stupid but I turned to this community for help because I cannot seem to be able to find a solution!
Thank you very much in advance for any help!
Seems to be workable with a dummy model. I didn't got the point how filter ID, so if it creates a problem let me know how you handle ID. Then I changed fact to facts as fact is a function. Also, I'm not sure about the workability of the measure at your real model. Hope you will give some feedback.
Amount Measure =
VAR ValidDate=
calculate(
max(facts[Valid_to])
,ALLEXCEPT(facts,facts[ID])
,facts[Valid_to]<=MAX(Dates[Date])
)
Return
CALCULATE(
SUM(facts[Amount])
,TREATAS({ValidDate},facts[Valid_to])
)

Finding Previous year Sales in Power BI with week number

I am trying to find the Previous year sales for the same week in Power BI.I dont have any date column.
I have two table one is FACT Indicators table as shown below:
and one sales table( Fact Sales table):
I want to create one calculated field namely(Sales Previous Year) to show the previous year sales for the same week .
In 'Fact Indicators' table 'PY 52 week flag' filed shows if this week id is Previous year or not.
Week column shows the week number from 1 to 52 weeks .
Week Id shows the unique number per Market key.
'Market_Week Id Key' is the common joining key between FACT Indicators table and Fact Sales table
Please help me to find the formula for calculated field.I dont have the date field in my raw data
Every time you deal with anything related to dates, you will need to add what we call a date dimension. It will save you tons of headaches. Once you have it in you will be able to hook it into the creation of the calculated filed.
you can google power bi or ssas date dimension and find tons of information on it.
Yeah! I guess SQL Technical team can be a tough crowd.... Well! In this case, I would recommend bringing the Year into FactSales Table from Fact Indicator . You have two options here with physical relationship set up between Market Week Id Key in both tables you can build a calc column with
Year = CALCULATE(VALUES(FactIndicators[Year]))
or without relationship use LOOKUPVALUE on WeekId
Year = LOOKUPVALUE(FactIndicators[Year], FactIndicators[WeekId], FactSales[WeekId])
Sales Last Year calc colum :
SalesLastYear =
CALCULATE (
SUM(FactSales[SalesThisYear] ),
TOPN(1,
FILTER(
FactSales,
FactSales[Year] < EARLIER(FactSales[Year])
&& FactSales[Key] < EARLIER(FactSales[Key])
)
)
)

Filter table based on a specific date plus 7 days

I have a table containing a date field (from 1 March 2020 to now) that I need to filter to a specific date and the previous 6 days to give complete week's data. So if I chose 30 March I'd get a table of 24 March to 30 March. If I then chose 31 March the table would show 25 March to 31 March.
I can use a date slicer to choose a range of dates but I want to be able to pick a single date, with Power BI automatically selecting the earlier date.
Any pointers much appreciated.
Mark.
You can create two measure - one for Slicer selected date and Another one with 7 day minus from the selected date as below-
Considering your date table name is- Dates
selected_date = SELECTEDVALUE(Dates[Date])
seven_day_starts_from = DATEADD(Dates[Date],-7,DAY)
Now create your calculated measure first like-
total_sales = SUM(Sales[sale])
Here comes how you will always calculate last 7 days sales considering the selected date in the slicer-
7_day_sales =
(
CALCULATE(
[total_sales],
DATESBETWEEN(
'Dates'[Date],
[seven_day_starts_from],
[selected_date]
)
) + 0
)
Remember, this is just a sample flow showing how it should work. You should try to follow the steps with your data and table structure. Dates table is a calendar table and Sales table is connected to the Dates table using the Date column.

Creating an measure to compare week-over-week developments

My dataset includes information from at 26 different weeks. It lists all the open items from an accounts receivable database for each of the 26 weeks. Each of the report dates is exactly 7 days apart.
I am trying to compare the current receivables with the amount of the last week.
I thought that I will just extract the last report date with
LastReport:=LASTDATE(Report Date)
which gave me indeed the last report date. I go back 7 days with
PriorWeek:=DATEADD(LastReport;-7;DAYS).
This worked fine.
However, when I try to calculate the sum of last week using
CALCULATE(SUM(Total AR);Reportdate=PriorWeek)
I can an error that I cannot compare date and text fields.
I have checked the report date column is set to date.
What am I doing wrong?
I would say 'No need of ranking the Dates'. My solution is below using calculated columns:
Amount Variance =
VAR _PrevBlank =
ISBLANK ( [PrevWeek Amount] )
VAR _Amount = [Amount]
VAR _PrevAmount = [PrevWeek Amount]
VAR _Variance =
IF ( _PrevBlank, 0, _Amount - _PrevAmount )
RETURN
_Variance
I would suggest creating a date index using RANKX
RankDate = RANKX(Table1,Table1[Report Date],,ASC)
Then you can either create a calculated column that holds the previous week value
PreviousWeekCol = LOOKUPVALUE(Table1[Total AR],Table1[RankDate],Table1[RankDate]-1)
Or create a calculated measure that holds the prior week value
PreviousWeekMeasure =
VAR MaxDateIndex = MAX(Table1[RankDate])
RETURN CALCULATE(SUM(Table1[Total AR]),Table1[RankDate]=MaxDateIndex-1)
