I am new to programming with Dax. Why doesn't the bottom table, which has Q5_2 Let at få aftale Total as values, show 8684 for all table rows, when it has been ALL'd in the measure ??
The function ALL() removes filters from a table or column. However, if applied on a column, only filters for that specific column are removed; other filters might still be in effect. I'm guessing that Power BI has problems with the special character in your column name, because I can see only one column and your measure in the table.
Here is an example of how removing the filter from the column should return the total amount of rows in that table:
If you add an additional column to the table though, data is filtered by the second column as well, bypassing the ALL() on the first column:
Now to solve your problem: you could write ALL(Data) instead of ALL(Data[Q5_2 Let at få aftale]), removing filters from the whole table and not just the whole column.
But also, I don't see why you would need CALCULATE() here. You can make the measures even shorter:
Number of all rows, regardless of filters: COUNTROWS(ALL(Data))
Number of rows, filters applied: COUNTROWS(Data)

You'll need to fix this in the data model by introducing a Customer_Sport linking table with bi-directional cross-filtering to Customer.
I have Table 1. It is filled with dates a inspection is going on. Plumbing or Garden inspections for example.
Table 2 links to these appointments and has additional columns with details such as a Person assigned to the inspection, and what property the inspection is at. I need these two tables to be separate as described, and they are linked by a simple ID column.
Is it possible at all to add a column to Table 2 called 'Last Date of Plumbing Inspection'. The idea is for any given Property in Table 2, there can be multiple inspection entries in Table 1 for it. The point of this column is that it should look in Table 1, find the matching ID, find the latest inspection date out of all the Plumbing-related inspections, and then set the column value to that.
The problem I am having with this is it seems like calculated columns can ONLY implement logic using the columns of the table the calculated column was created in. In Table 2, I can't create a calculated column that interacts with Table 1 at all. I could create a look up column, but I can't combine calculated columns with look up columns. Is there a way to build this latest inspection date column without too much complexity?
Actually you can create a Rollup field and put a MAX aggregate function for achieving your requirement from related table. Read more
My company has tasked with slicing the information on turnover and to create different graphs.
My source data looks like this: Relevant columns are: Voluntary/Involuntary, Termination Reason, Country, Production, and TermDateKey
I am trying to get counts using different filters on the data. I managed to get the basic monthly total using the formula:
Term Month Count = GROUPBY('Turnover Source','Turnover Source'[TermDateKey],"Turnover Total Count", COUNTX(CURRENTGROUP(),'Turnover Source'[TermDateKey]))
This gave me a new sheet with the counts for each month.
Table that shows TermDateKey on Column 1, and Counts on column 2
I am trying to add onto this table by adding counts but using different filters.
For example, I am trying to add another column that gives me the monthly count but filtered for 'Turnover Source'[Voluntary/Involuntary]=="Voluntary". Then another column for 'Turnover Source'[Voluntary/Involuntary]=="Involuntary" and so on. I have not found anywhere that shows me how to do this and when I add in the FILTER function it says that GROUPBY(...) can only work on CURRENTGROUP().
Can some one point me to a resource that will give me the solution I need? I am at a loss, thank you all.
It looks like you may not be aware that you don't have to calculate all possible groupings with DAX formulas.
The very nature of Power BI is that you use a column like "Termination Reason" on an X axis or in the legend of a visual. Any measure that you have created on values of another column, for e.g. a count of all rows, will then automatically be calculated to be grouped by the values in "Termination Reason", giving you a count of each of the values in the column.
You do NOT need DAX functions to calculate the grouping values for each measure for each column value combination.
Here is some simple sample data that has been grouped into dates and colours, one chart showing a count of each colour and one chart showing a sum of the Value column. No DAX was written for that.
If your scenario is different, please explain.
I have implemented laravel dataTable as a service.
The initial two columns are actual id and names so, I am able to sort it asc/desc after the table renders.
But the next few columns renders after performing few calculations, i.e. these values are not fetched directly from any column rather it is processed.
I am unable to sort these columns where calculations were performed, and I get this error. And I know it is looking for that particular column for eg outstanding_amount which I don't have in the DB, rather it is a calculated amount from two or more columns that are in some other tables.
Any Suggestions on how to overcome this issue?
It looks like you're trying to sort by values that aren't columns, but calculated values.
So the main issue here is to give Eloquent/MySql the data it needs to provide the sorting.
// You might need to do some joins first
->addSelect(DB::raw('your_calc as outstanding_amount'))
->orderBy('outstanding_amount') // asc can be omitted as this is the default
// Anternative: you don't need the value sorted by
// Don't forget any joins you might need
->orderByRaw('your_calc_for_outstanding_amount ASC')
For SQL functions it'll work as follow
->addSelect(DB::raw('COUNT(products.id) as product_count'));
->orderByRaw(DB::raw('COUNT(products.id)'),'DESC');
I have two tables in PowerBI. One called 'Fact_WorstInstance' contains rows of (Index,Instance). For example:
1,2
2,1
3,2
One called 'Fact_AllInstances' contains rows of (Index,Instance,Value). For example:
1,1,'Red'
1,2,'Green'
2,1,'Amber'
2,2,'Red'
2,3,'Brown'
3,1,'Green'
3,2,'Blue'
The first table is essentially a pointer to the worst entry in the second table for the given index (as categorised by some external system).
There is a slicer on which Indexes are visible to the user.
What I want to do is find the worst instance value for the highest visible Index in the 'Fact_WorstInstance' table, and then get all the Index and Value rows from the 'Fact_AllInstances' table for that Instance.
For example, if the slicer isnt filtering then (3,2) should be the active row from from the 'Fact_WorstInstance' table and this should be used to get Instance 2 from the 'Fact_AllInstances' table
1,2,'Green'
2,2,'Red'
3,2,'Blue'
from the 'Fact_AllInstances' table.
I tried to do this in many different ways, by creating a measure on the 'Fact_WorstInstance' which gives the highest visible row. And then use this measure to create a calculated column on the 'Fact_AllInstances', with 1 for worst and 0 for not worst. And then use this calculated column as a filter in PowerBI.
The measure itself gives the expected value. The problem I have is when the measure is used to create the calculated column, I cannot find a way to stop the Index being filtered based on the row of calculated column - and therefore the measure outcome changes for each row.
My measure:
Worst Entry = CALCULATE(FIRSTNONBLANK(Fact_WorstInstance[Instance],1),filter(ALLSELECTED(Fact_WorstInstance),Fact_WorstInstance[Index]=MAX(Fact_WorstInstance[Index])))
My column:
WorstColumn = if(Fact_AllInstances[Instance]=[Worst Entry],1,0)
So instead of getting the output above, I get
1,2,'Green'
2,1,'Amber' --> because for Index 2, the measure gives index 1 as worst
3,2,'Blue'
This is a possible solution you might want to implement.
First of all, calculated columns are not affected by slicers/page filters, you will need to create a measure for that, so the way your are appraching the problem won't work.
Create an additional calculated table that holds unique instances values. In Power BI, Modeling tab there is a icon for creating a New Table, where you can use an expression to produce the table.
Use this expression:
IsntancesCalcTable = VALUES(Fact_WorstInstance[Instance])
Now you have a table called InstancesCalcTable in your model.
Drag the Instance column in the InstancesCalcTable and drop it in the Instance column of the Fact_WorstInstance, this will create a relationship between InstancesCalcTable and Fact_WorstInstance via Instance. A line between both tables will be drawn in the Relationships view, double click that line and you will see the Edit Relationship window.
Make sure it looks like this:
Then do the same for creating the relationship between InstancesCalcTable and Fact_AllInstances.
You will end with a model like this:
Then you can use Index column in the Fact_WorstInstance table, in a slicer and it will filter the Fact_AllInstances table to get only the instances selected.
However if you don't have any filter all rows in Fact_AllInstances will be shown.
