I have made two calculated field in my quicksight anaysis - 'Correct Prediction' and 'Total Count'
Formulas used for above two calculated are -
Correct Prediction = ifelse({best_exp_rank} <= 15,1,0)
Total Count = count({best_exp_rank})
Now I made a pivot table and kept the above columns as values(Correct Prediction(Sum), Total Count(custom)).
When I'm trying to make a third column which is (Correct Prediction/Total Count) as a calculated field.
I face the following error.
mismatched aggregation. custom aggregations can’t contain both
aggregate "count" and non-aggregated fields
“count("best_exp_rank")”, in any combination.
Can anyone please help me with this problem? Please comment if you need any extra information
Add a calculated field like -
(sum({Correct Prediction}) / {Total Count}) * 100

I need to calculate ProductPrice[overall] * DealerProduct[quantity] but the tables aren't related. I have been trying to use Sumx with related table but no matter what I do I cant get it to display the correct information.
I am currently trying to create a column in ProductPrice to just get the quantity in this table but I don't even know if that's possible.
So far I have tried:
Column in ProductPrice -
SUMX(RELATEDTABLE(DealerProduct),ProductPrice[overall]).
Column in ProductPrice -
SUMX(RELATEDTABLE(DealerProduct),DealerProduct[quantity]).
Column in ProductPrice -
CALCULATE(SUMX(RELATEDTABLE(DealerProduct),DealerProduct[quantity]) / COUNTROWS(DealerProduct))
So far the last one has been closest but still off.
Anyone have any ideas here?

I have an employee dataset and I'm trying to display the proportion of BAME staff only as a KPI. My dataset has duplicate lines (staff who have more than 1 role) and so I have to use a distinct count of their staff IDs (i.e. cannot use measure values or SUM) as I want to measure ethnicity per person not per role. The only way I can get the % of BAME across the population is by having all other categories visible however I am looking for a way to display the % of BAME across total only. For example in a table calc BAME = 12%, Non-BAME=85% and Unknown=3% - I want to keep the 12% only to put on my dashboard.
I've not needed to do this in Tableau before and I'm quite new to the software. Is there a way to do this? I thought that perhaps I would need to do an IF statement similar to Excel but the below syntax returns an error.
IF [Ethnic Group]="BAME" THEN COUNTD([Staff ID]) / COUNTD([Staff ID]) END
Thank you so much in advance!
COUNTD(IF [Ethnic Group]="BAME" THEN [Staff ID] END)/COUNTD([Staff ID])
Basically, I’d like to get one entity totals, but calculated for another (but still related/associated!) entity. Relation type between these entities is many-to-many.
Just to be less abstract, let’s take Trips and Shipments as mentioned entities and Shipments’ weight as a total to be calculated.
Calculating weight totals just per each trip is pretty easy task. Here is a table of Shipments weights:
We place them into some amounts of trucks/trips and get following weight totals per trip:
But when I try to show SUM of Trip weight totals (figures from 2nd table) per each related Shipment (Column from 1st table), it becomes much harder than I expect.
It should look like:
And I can’t get such table within Power BI.
Data model for your reference:
Seems like SUMMARIZE function is almost fit, but it doesn’t allow me to use a column from another table than initialized in the function:
Additional restrictions:
Selections made by user (clicks on cells etc.) should not affect calculation anyhow.
The figures should be able to be used in further calculations, using them as a basis.
Can anyone advise a solution? Or at least proper DAX references to consider? I thought I could find a quick answer in DAX reference guide on my own. However I failed to find a quick answer.
Version 1
Try the following DAX function as a calculated column inside of your shipments table:
TripWeight =
VAR tripID =
RELATED ( Trips[TripID] )
RETURN
CALCULATE (
SUM ( Shipments[ShipmentTaxWeightKG] );
FILTER ( Shipments; RELATED ( InkTable[TripID] ) = tripID )
)
The first expression var tripID is storing the TripID of the current row and the CALCULATE function gets the SUM of all of the weight for all the shipments that belong to the current trip.
Version 2
You can also create a calculated table using the following DAX and create a relationship between the newly created table and your Trips table and simply display the weight in this table:
TripWeight =
GROUPBY (
Shipments;
Trips[TripID];
"Total Weight KG"; SUMX ( CURRENTGROUP (); Shipments[ShipmentTaxWeightKG] )
)
Version 3
Version 1 and 2 are only working if the relationship between lnkTrip and Shipment is a One-to-One relationship. If it is a many-to-one relationship, the following calculated column can be created inside of the Trips table:
ShipmentTaxWeightKG by Trip = SUMX(RELATEDTABLE(Shipments); Shipments[ShipmentTaxWeightKG])
hope this helps.
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.
I am trying to add two currency columns in a calculated column but am getting a #NULL! error.
This seems pretty straightforward but its my first time doing this in SharePoint.
SharePoint 2010 with Excel Services available.
Have create List with required columns:
Approved Value column Type = Currency
Pending Value column Type = Currency
Total Value column
Calculated (calculation based on other columns)
Type = Currency
Formula: =[Approved Value]+[Pending Value]
The values in other columns are indeed currency, but the Total shows #NULL! for all items.
I can't see anything done incorrectly.
What should I be looking for to resolve this problem?
Try using the ISBLANK function to previously check if any of the value is null.
Reference: ISBLANK function
I ended up using NZ(Value, 0)
=NZ([Approved Value],0)+NZ([Pending Value],0)
Though not sure how NULLs ended up in field or why SharePoint couldn't deal with them without this special treatment.
