I have TABLE A
In that table I have a measure with values like so:
Targets|
--------
4 |
5 |
6 |
In the same table I have a calculated column (summed totals) like so:
Totals |
--------
10 |
11 |
12 |
Because this is a direct query data source, query editor is disabled and manipulation must be done through DAX formulas.
I would like to do a simple operation of Targets-Totals
Code I've tried for a calculated column:
test = TableA[targets] - TableA[totals]
However this results in an error:
The column TableA[test] cannot be pushed to the remote data source and cannot be used in this scenario.
How can I create a new column with the above operation considering the fact that one column is a 'measure ' and the other a 'calculated column'
In this case, you will need a measure that does a row by row calculation, but not as a calculated column. For this you will need SUMX which will do a iteration.
Your measure should be:
New Measure = SUMX(TableA, [targets] - [totals])

I'm struggling to create a Measure that sums a column and have it filter out duplicate IDs while taking only the latest row.
For example, there is a table as such:
UID | Quantity | Status | StatusDate
aaa | 3 | Shipped | 11/1/2020
aaa | 3 | Delivered | 11/5/2020
bbb | 5 | Ordered | 10/29/2020
ccc | 8 | Shipped | 11/4/2020
So the idea would be to sum the quantity, but I would only want to count quantity for id "aaa" once and only count towards the latest status ("Delivered" in this case). I would make a visual that shows the quantities with status as its axis. I also need to add a date Slicer so I could go back in time. So, when I go before 11/5/2020, instead of "Delivered," it would switch back to "Shipped."
I tried several methods:
SUMMARIZE to a table filtering "MAX" date value if UID is the same. I found this doesn't work with the date slicer since it seems like it is not actually recalculating the filtering and just slicing away rows outside of the dates. Seems to be the same whether the SUMMARIZE is set as a new table or VAR in the Measure.
CALCULATE seems promising but I can't seem to figure out a syntax
that filters that I need. Example of one that doesn't work (I also tried SUMX instead of SUM but that doesn't work either):
CALCULATE(
SUM(Table1[Quantity]),
FILTER(Table1, [StatusDate]=MAXX(FILTER(Table1,[UID]=EARLIER([UID])),[StatusDate])
)
I also tried adding a column that states whether if the row is "old" as well as a numerical "rank" to the different statuses. But once again, I run into the issue where the date slicer is not exactly filtering to recalculate those columns. For example, if the date slicer is set to 11/3/2020, it should add "3" to "Shipped" instead of "Delivered." But instead of that, it just removes the row which tells me that it is not actually recalculating the columns (like #1).
Any help would be appreciated :-) Thank you!
You can try something like this:
Measure =
VAR d = LASTDATE(Table1[StatusDate])
VAR tb = SUMMARIZE(FILTER(Table1, Table1[StatusDate] <= d),
Table1[UID],
"last", LASTDATE(Table1[StatusDate]))
RETURN CALCULATE(SUM(Table1[Quantity]), TREATAS(tb, Table1[UID], Table1[StatusDate]))
The tb variable contains a table which has the latest date per UID. You then use that to filter your main table with the TREATAS function.
One other alternative is to create a table with the RANK function ordered by date and then doing a SUM over that table, where Rank = 1.
I have a table that contains multiple columns with their named having either the suffix _EXPECTED or _ACTUAL. For example, I'm looking at my sold items from my SoldItems Table and I have the following columns: APPLES_EXPECTED, BANANAS_EXPECTED, KIWIS_EXPECTED, APPLES_ACTUAL, BANANAS_ACTUAL, KIWIS_ACTUAL (The Identifier of the table is the date, so we have results per date). I want to show that data in a table form, something like this (for a selected date in filters:
+------------+----------+--------+
| Sold items | Expected | Actual |
+------------+----------+--------+
| Apples | 10 | 15 |
| Bananas | 8 | 5 |
| Kiwis | 2 | 1 |
+------------+----------+--------+
How can I manage something like this in Power BI ? I tried playing with the matrix/table visualization, however, I can't figure out a way to merge all the expected and actual columns together.
It looks like the easiest option for you would be to mould the data a bit differently using Power query. You can UNPIVOT your data so that all the expected and actual values become rows instead of columns. For example take the following sample:
Date Apples_Expected Apples_Actual
1/1/2019 1 2
Once you unpivot this it will become:
Date Fruit Count
1/1/2019 Apples_Expected 1
1/1/2019 Apples_Actual 2
Once you unpivot, it should be fairly straightforward to get the view you are looking for. The following link should walk you through the steps to unpivot:

Hope this helps.
I have im my model table that contains data from reports based on monthly reporting of employees with column names "ReportDate" and enployye numbers.
I want to check that there is no gaps between the monthly dates to each employee with DAX.
For example:
EmpNum | ReportDate | CheckColumn
111 | 30.08.2019
111 | 30.09.2019
111 | 31.10.2019
222 | 30.08.2019
222| 31.10.2019 ----------> Here I want alert in my CheckColumn
Can someone find me a solution?
First you need to create a index column. Go to Edit Queries > Add Column > Index Column, starting with 1 for example.
Next you add a column with DAX which has a shift of 1 to the original column with this expression (make sure this column is from the same date format as your original column; Modelling > Format):
ShiftColumn = DATEVALUE(CALCULATE(MAX('Table'[Report Date]);FILTER('Table';'Table'[Index]=EARLIER('Table'[Index])-1)))
Next add the column with the check:
Column 2 = IF(DATEADD('Table'[Report Date].[Date];-1;DAY) = 'Table'[ShiftColumn]; TRUE(); FALSE())
The result:
For example: if I just have this table
---------
| power |
---------
| 100 |
---------
I just want the value 100 (a number in this case). And if for example, the value is a string I want to have the value of the string too.
I need this to incorporate this subquery into another query, more precisely in a condition function.
PS: I use M language (Power Query in POWER BI Desktop)
After you load the table in the query editor, you can right-click on the value 100 and select Drill Down. This will give you a single value instead of a table.
It does this using the M code Source{0}[Power] where 0 is the row index and Power is the column.
let
Source = <data source for your table>,
Power = Source{0}[Power]
in
Power
There are other ways you can do this too. For example, the first element in the table's column:
List.First(Source[Power])
I have a dataset more or less like this one:
DATE | VALUE
01/01/2011 | 100
02/01/2011 | 150
02/01/2011 | 550 --> Repeted on purpouse
.
.
12/01/2016 | 320
Now I need to have a calculated measure with only the values within a date range, I tried in many ways but with no success, the only one I managed to get it work is the follow DAX syntax:
consuntivo = CALCULATE(SUM(provadat[valori]);provadat[datazione]>=DATE(2015;01;01)&&provadat[datazione]<=DATE(2016;01;01))
but it generates the following:
So basically I need a DAX Query with distinct sum for each dates. How can I achieve that?
Two methods.
In the Table visualization you can choose Sum as the summarize option for the column valori.
Or using DAX, it'll be just simple as
consuntivo = SUM(provadat[valori])
You don't need to handle the date logic particularly because Power BI will handle it based on the context (data columns you used with the measure).
So basically what I was missing was to add filters.
xxx = Calculate(SUM(provadat[valori]);FILTER(VALUES(provadat);provadat[datazione] <= DATE(2017;01;01) && provadat[datazione] >= DATE(2016;01;01)))
