Consolidate filter and measure? - powerbi

Is there a better way of trying to filter a table and apply a average to the filtered results?
Currently research online articles has brought me to creating a virtual table (CALCULATETABLE) and then a separate measure to AVERAGE the column value I require.
Filtered Table below
filtered_table = CALCULATETABLE ('ReportRawFigures',
ReportRawFigures[days_since_completed] < 29,
ReportRawFigures[3rd_party] = "Bloggs",
ISBLANK(ReportRawFigures[time_to_complete]) = FALSE(),
ISBLANK(ReportRawFigures[last_confirmed_issue]) = FALSE(),
ReportRawFigures[issue_status] = "")
Then a simple measure added:
average = AVERAGE(filtered_table[column])

I'm not very bright... I figured it out.
You create the filtered table, then when you build you visual you simply select the column and chose to average its output..
Hope this helps anyone looking like I first did.

SUMX in Stacked Column chart

I'm hoping for some help with my measures. My data is quite sensitive so it's not easy to share. I've attempted to mock up as sales so hope it makes sense.
https://1drv.ms/u/s!Ap6q8W-mvm27g-dWehgkV6-p33VVsA?e=bGj3nV
I have written a measure to count the number of resales by TransactionID. I then use a sumx to total the resales by Transaction ID.
I've added this measure to a matrix against Month for Banding and this shows the correct row and column totals.
In the FACT Salestable, I have a field 'Tier'. When I attempt to add 'Tier' to a stacked column chart using the same measures, the data is incorrect. I think it is because the sumx is losing the filter created in the first measure but I don't really understand how to rectify this and have been trying for days!
Is anyone able to identify where my measures are incorrect - Id like to try to understand what exactly I'm asking the measure to do so I know where I'm going wrong for future work! Any help would be very much appreciated - thank you!
MEASURE 1:
CountResales =
Var _Cust = Max (FACTSales[CustomerID])
Var _Date = CALCULATE(min(FACTSales[DateOrigSale]),ALLSELECTED(FACTSales),FACTSales[CustomerID]=_Cust)
Var _ID = CALCULATE(min(FACTSales[CohortID]),ALLSELECTED(FACTSales),FACTSales[CustomerID]=_Cust,FACTSales[DateOrigSale]=_Date)
Var _CountResales =
CALCULATE(DISTINCTCOUNT('DIMReSales transactions'[TransactionID]),
VALUES('DIMReSales transactions'[TransactionID]),'DIMReSales transactions'[CohortID]=_ID,
'DIMReSales transactions'[New Sale]=1)
Return
_CountResales
MEASURE 2:
SumResales = Sumx(values('FACTSales'),[CountResales])

PowerBI: Aggregate Measure correctly by condition on DATEDIFF

I have the following Table:
BaseTable
It represents processes with a certain category.
And there is also a Date Table over column TIMESTAMP.
I would like to show a Measure based on another Measure that calculates the Date-Difference until the selected Date.
So first this is how I calculate the Date-Difference:
AGE =
VAR SELECTED_DATE = CALCULATE(MAX(DATUM[Date]), ALLSELECTED(DATUM))
VAR STARTDATE_PROCESS = Calculate(MAX(Workflow[MIN_TIMESTAMP]),DATUM[Date]<=MAX(DATUM[Date]), ALL(DATUM[Date]))
RETURN
DATEDIFF(STARTDATE_PROCESS,SELECTED_DATE,DAY)
Now I want to use a Measure which depends on the result of AGE, like
NEW = IF([AGE]<=3,CALCULATE(COUNT(Workflow[PROCESS]),DATUM[Date]<=MAX(DATUM[Date]),ALL(DATUM)))
or
OLD = IF([AGE]>3,CALCULATE(COUNT(Workflow[PROCESS]),DATUM[Date]<=MAX(DATUM[Date]),ALL(DATUM)))
The Measures AGE, OLD and NEW look like that with the Base Table:
Measures
As you can see the aggregation is not working correctly:
Result_Wrong
But it should be like that
Result_Correct
Any idea how to fix that?
Thank you!
So the problem is that the subtotal is calculated at a whole different context, and because your Age measure is based on the MAX(Workflow[MIN_TIMESTAMP]) that won't take into account that there can be multiple processes.
To do what you want, you need to change the New and Old measures to perform an aggregation per process and then return the result of that. Something like this:
New_agg =
VAR tbl = ADDCOLUMNS(CALCULATETABLE(VALUES(Workflow[Process]), ALL('Date')), "age", [Age], "count_process", CALCULATE(COUNT(Workflow[Process]), ALL('Date')))
RETURN SUMX(tbl, IF([age]<=3, [count_process]))

Let me know if below solution is working
Unfortunately I am unable to generate the dummy data that you have been using, so Created my own data for developing the solution.
Now from this data I have calculated the difference of dates and put it as Age
Now to get the count of process for the condition like yours, I have created two formulas and the result is:
Logic I followed here is, instead of creating measure I have created columns and took the sum of those columns which will give the data you need as sum of those columns.
Column for New:
New = IF((Sheet1[Age]) > 20, 1,0)
Column for Old:
Old = IF((Sheet1[Age]) < 20, 1,0)
Now place both formulas in "Values" and take sum as the aggregation.
Final result is

Is there a way to calculate a percentage over the grand total while keeping more than one filter set?

I’m wondering if there is a way, in a table, to calculate the percentage over a grand total.
I think this is a fairly simple issue, but I really can't wrap my head around it.
I have a table with a count, divided into different Categories:
I also have several slicers:
What I would like the table to show is the percentage of the current selection over the grand total, while keeping at least other two filters set (the Year(Anno) and another one set on the entire page).
If I select in the slicer “Range Scostamento %” a value, the table will obviously update the numbers:
The value I’m looking for is the “weight” in percentage of the filtered values over the total value.
So for example, for the first row I will have 317/14.793 = 0,0214 = 2,14% and so on.
I think my question has something to do with the SELECTEDVALUE/ALLSELECTED, maybe KEEPFILTERS, but I really don’t know how to make it work.
Thanks in advance!

If I understand your requirement correct, you need these below measures for your purpose-
contratti = count(table_name[column_name])
grand_total =
CALCULATE(
count(table_name[column_name]),
ALL(table_name)
//-- ALL will return count of entire table
//-- you can use ALLSELECTED if you wants the
//-- grand_total for filtered data based on slicer
)
percentage = [contratti] / [grand_total]

How to select the last value of the day with DAX in Power BI

I am new to power BI and stuck with an issue. I have my model as follows:
Date Dimension
Measurement Fact
The date column in Date Dimension is link to measuredate in Measurement Fact
Below is a sample data:
NB: In edit query, I have changed the type of measuredate to Date only.
I have tried the measure below but it doesn't work the way I want. It will sum all the values of the day but what I want is the last value of the day:
day_fuel_consumption =
CALCULATE (
SUM ( measurement[measurementvalue] ),
FILTER (
measurement,
measurement[metername] = "C-FUEL"
&& measurement[measuredate] = MAX ( measurement[measuredate] )
)
)
My Goal is to get 29242, i.e the last value of the day. Remember that measuredate is a Date field and not Datetime (I changed to Date field so that my Year and Month filter can work correctly). I have changed the type in edit query.
Changing your measure to use a variable could be the solution:
DFC =
var maxDate = MAX(measurement[measuredate])
return
CALCULATE(
SUM(measurement[measurementvalue]),
measurement[measuredate] = maxDate
)
However, you should keep the datetime format for measureDate. If you don't want to see the time stamp just change the format I power bi. Otherwise power bi will see two values with max date and sum them, instead of taking the last one.
Well, if you want to avoid creating a measure, you could drag the fields you are filtering over to the visual filters pane. Click your visual, and scroll a tiny bit and you will see the section I am referring to. From there, just drag the field you are trying to filter In this case, your value. Then select "Top N". It will allow you to select a top (number) or bottom (number) based on another field. Strange enough, it does allow you to do top value by top value. It doesn't make sense when you say it out loud, but it works all the same.
This will show you the top values for whatever value field you are trying to use. As an added bonus, you can show how little or how many you want, on the fly.
As far as DAX goes, I'm afraid I am a little DAX illiterate compared to some other folks that may be able to help you.
I had to create two separate measures as shown below for this to work as I wanted:
max_measurement_id_cf = CALCULATE(MAX(measurement[measurementid]), FILTER(measurement, measurement[metername] = "C-FUEL"))
DFC =
var max_id_cf = [max_measurement_id_cf]
return
CALCULATE(SUM(measurement[measurementvalue]), measurement[measurementid] = max_id_cf)

Obtain MAX of column and display for each row

I'm trying to obtain the MAX of a particular column in a Power BI Report and place this as a new Measure within each ROW of the same dataset. Please see the example below.
Is this possible in DAX and via DirectQuery/LiveConnection? The report is pointing to a tabular model but due to outside factors the measure must be created in the report.
Thanks
You can accomplish this a few ways. Essentially, you need override the filter context so that the MAX function isn't just running over whatever slice you're showing in the visual. Using CALCULATE or the iterator function MAXX, set the wrap the table in the ALL() function to override the context and calculate max over all rows.
= CALCULATE(MAX([Calendar`Year]), ALL('Smithfield_Fiscal_Calendar'))
or
= MAXX(ALL('Smithfield_Fiscal_Calendar'), [Calendar`Year])
To get the breakout by date, you'll need to include a Date table in your model. PowerBI makes this possible with a few different DAX options. As an example, go to your Model tab, click 'New Table' and put in the following expression:
MyCalendar = CALENDAR(DATE(2019,1,1), DATE (2019,1,10))
This is a little trivial -- you'd want to use a useful range of dates but this one matches your example above. Next, add a column to [MyCalendar]
CalendarMonthYear = month([date]) & "-" & year([date])
Go to your budget table and add a similar field
BudgetMonthYear = month([date]) & "-" & year([date])
Go into your Model view and create a relationship between CalendarMonthYear and BudgetMonthYear. This will associate every date in the date table with the particular budget row from your budget table.
Hope it helps.
