Does ALL function ignore filters applied in Power Query? Say that I want to count rows, say number 2, in a specific column (x_channel), but that number is filtered out because of a filter in another column (associate.name) in the same table. I'm trying to use ALL function, but the measure doesn't work. Is there something wrong with my syntax?
Telefon = CALCULATE(COUNTROWS(TICKET), ticket[x_channel]=2, ALL(TICKET[ASSOCIATE.name]), USERELATIONSHIP(DIM_DATO[Opprettet], TICKET[Created]))
Thanks!
PowerQuery (language: M) and PowerBI (language: DAX) have nothing to do with one another.
PowerQuery handles the ingestion of data at refresh time. After that, the only data PowerBI has in its data model is the data that was provided to it by PowerQuery.
If you have filtered data in PowerQuery, then using ALL() in DAX will have no effect.

I am a PowerBi beginner and would like to know if it is possible to create a table report that behaves like explained in the attached picture (according to the fact table I have).
I tried to do it with a DAX measure using the following formulas but it does not work as I wish :
CALCULATE(SUM('Fact'[Invoice]),'Fact'[Customer] = SELECTEDVALUE('Fact'[Customer]))
CALCULATE(SUMX('Fact','Fact'[Invoice]),'Fact'[Customer]=SELECTEDVALUE('Fact'[Customer]))
The slicer does not filter the table in order to get all the product in the table even if the customer did not buy one.
Is it possible to do it ?
Many thanks
I have a table visualisation that shows the populations of countries and a toggle switch that flips between 'sold' and 'unsold'. (This works with a measure that checks is a country is present in a sales table and assigns a 1 or 0 which is then used as a filter on the table visualisation).
Various slicers in the dashboard are used to filter the data model and retain the details of sales. When 'unsold' is selected therefore, the relevant countries are already filtered out of the countries data table and it is not possible to display them with their populations.
At the moment the workaround is to use a duplicate countries table that only has a one way filter, so that the rows remain regardless of filtering. This means that other slicers which interact with the rest of the data model don't filter the table visualisation as desired.
I am sure this must be possible using some combination of CALCULATE(), FILTER() and ALL() but I haven't managed to achieve this.
N.B. I can force the unsold countries to appear in a table visualisation using a constant measure (with formula: measure_name = 0) in a column .
Apologies if this is not very well explained, any help much appreciated.
Thanks for reading,

Real scenario is more complicated hence not screenshotting from PBI.
Is it possible to refer from Power Query (M) to DAX calculated table? I would like to get DAX table as a source to my power query.
The purpose. I have grouping table made in DAX. I would like to make econometric model with R. So I would like to transform the DAX table with R to get the model parameters. I would like to use these parameters further in DAX measures (not just display them).
Currently I dump the DAX grouping table to Excel file and then pull it up with Power Query.
Actually, there is a way.
DISCLAIMER: This is a hack. You should not rely on this way.
1. Create DAX calculated table
Input any DAX formula that evaluates to a table in Modeling > New Table.
2. Check port number using DAX Studio
Connect to your PBI Desktop data model using DAX Studio, and check the port number where the data model is hosted. It should be displayed in the right bottom of the window.
3. Import the table to Power Query
Click Get Data > Analysis Services and input the address (in my example "localhost:50293") to Server. Then navigate to your DAX calculated table.
it's not possible to refer to a DAX calculated table in M as it's loaded into DAX/Power Pivot engine after M has done the transformations. You can't write to a DAX table after loading into R as well. You can do grouping in M, or if needed run R in the Power Query. One approach that I have used has to load the data, duplicate the query, run a group/filter on the new query, then use that data in a later stage in the report.
Hope that helps
Jonee is correct. This is not possible. DAX calculated tables are computed after the M queries have loaded and you cannot feed them back into Power Query without saving them externally like you are currently doing.
The M language is more powerful than you might think and very likely could do the same grouping operations, though depending on what they are, it might be fairly difficult. You can also use R or Python script within an M query if you are more comfortable with those.
Is it possible to reference another table using M in Power BI?
I have a list of files in TableA and want to compare the data with a list in TableB.
I have done this in DAX by using related and was wondering does M have a similar function?
= SEARCH(related(keywords[keyword]),main[text],1,0)
I struggled to find this information too.
This is a snippet from a Power Query 'Advanced Editor' where I'm reading a minimum date from another table into a variable.
let
Source = #date(2015, 1, 1),
MinDate = List.Min(TableName[Date]),
...
Power Query List functions
Hopefully List is what you're looking for.
I'm trying to figure out how to get a measure to adhere to the filter set by a slicer in Power BI.
My DAX query is: Block Time Cost = SUMX( FILTER(v_Invoice_Line_Items, v_Invoice_Line_Items[IV_Item_RecID]=9), v_Invoice_Line_Items[billable_ext_price_amount])
I know very, very little about DAX so my initial query may be way off base.
It calculates as I expect, but when filter with a date range silcer the value does not update as expected or at all.
I'm pulling my data from two views in the same database, v_Invoice and v_Data_Combined. I have a page level filter on the row Record_Description to limit the data to the types I'm looking for and the measure pulls it's data from rows in the v_Data_Combined view.
The rows in v_Invoice are below.
A sample copy is here.
and the rows for v_Data_Combined, if you click they will enlarge.
A sample copy is here.
I have no relations set between the views.
How can I have a measure adhere to slicer filters?
The slicer has to be on the same table as the measures you're filtering, or on a table related to that table. If your slicer is on a column in v_Invoice and your data is from v_Data_Combined - and the 2 tables are unrelated in Power BI, the slicer from one table will have no effect on the data from the other table.
Without sample data (which can be fake data), it's hard to make further recommendations.
However, if the two tables you have aren't really related to each other, then I would recommend exploring the possibility of "lookup" tables. E.g. if you have Company_Name in both tables, then you might add a 3rd table that is a unique list of companies (their name, address, etc). Then, when you want to slice by company you would slice on this 3rd table. That slicer will then filter both related tables (without having to have the tables related to each other).
