it seems like PowerBI is auto-ordering my table and I don't know why. So, I have this table (that I exported from a Excel file)
Colonne 1
7
25
1
8
3
Whenever I do a New Mesure, with this formula:
Mesure = FIRSTNONBLANK(Feuil1[Colonne 1];0)
It gives me the number 1. If I do LASTNONBLANK, it returns me the number 25. So it clearly auto-order my dataset, but whenever I look in the «Data» tab of the software, I see that my data are ordered the way I want them to be.
Any idea on how to keep the default ordering?
Unfortunately, that's the exact behavior of FIRSTNONBLANK() and LASTNONBLANK(). They iterate the values of a column based on their native sort order (i.e. data type). Therefore, FIRSTNONBLANK would return the smallest number 1 and and LASTNONBLANK the largest number 25. And in general, you cannot make assumptions on sort order of values in a table or in a column when using DAX.
Therefore, my suggestion is that you can explicitly program the logic to find the target value. Say the table is sorted based on date, you can find the key of the earliest/latest date (based on your use case), then lookup the value using the key.
Target =
VAR TargetKey =
CALCULATE(
VALUES(Table1[Key]),
FILTER(
Table1,
Table1[Date] = MIN(Table1[Date]) // or MAX(Table1[Date])
)
)
RETURN
LOOKUPVALUE(Table1[Colonne 1], Table1[Key], TargetKey)

I have a table of number of visual:
visual_1000x123
0
1
I would like to use a dropdown list to let people select 0 or 1.
If 1 is selected, the calculate result will be xxx(let's say 55k).
If 0 is selected, the calculate will be 0.
Maybe I should mention that there is a time filter, which works well.
The result varies according to the selected period.
This measure keeps giving me 0:
measure = IF(MAX('Simulateur'[visual_1000x123])=0, 0,
CALCULATE(SUM('Prévision Leaderboard'[Budget_impressions/1000x123_et_1000x167])) +
CALCULATE(SUM('Prévision Middleboard'[Budget_impressions/1000x123_et_1000x167])))
This measure keeps return 55k:
measure = IF(MAX('Simulateur'[visual_1000x123])=1, 0,
CALCULATE(SUM('Prévision Leaderboard'[Budget_impressions/1000x123_et_1000x167]))+CALCULATE(SUM('Prévision Middleboard'[Budget_impressions/1000x123_et_1000x167])))
I also tried to multiply the number of visual, but it didn't return anything:
measure =
(CALCULATE(SUM('Prévision Leaderboard'[Budget_impressions/1000x123_et_1000x167])) +
CALCULATE(SUM('Prévision Middleboard'[Budget_impressions/1000x123_et_1000x167])))*MAX('Simulateur'[1000x123])
If I am understanding your question correctly, you just want to multiply a number in a column by a factor (which is in a slicer, or visual).
If that is the case you can do it simply as follows:
column1 * factor result = AVERAGE('Table'[Column1]) * AVERAGE('Table (2)'[factor])
Posting this answer myself.
It's due to my data structure. All the data was in one table and I should have them seperated into different tables.
I Have a TestTable that summarizes a table Receipts on the Month column and adds a column that counts the number of times (occurence) that each month appears in the Receipts Table.
TestTable = SUMMARIZE(Receipts, Receipts[Month], "TotalReceiptsIssuedInThisMonth", SUM(Receipts[Receipts Issued]), "OccurenceOfMonth", COUNT(Receipts[Month]))
I want to add two columns to this TestTable which will tell me the following:
Sum the TotalReceiptsIssuedInThisMonth of the TestTable and show the
value in each row
For each Month (row), divide the, TotalReceiptsIssuedInThisMonth by the SumOfTotalReceiptsIssued
I know I can click "New Column" and use these formulas:
AvgPercentageReceiptsIssuedInThisMonth = TestTable[TotalReceiptsIssuedInThisMonth]/TestTable[TotalReceiptsIssued]
TotalReceiptsIssued = SUM(TestTable[TotalReceiptsIssuedInThisMonth])
However, I need to integrate those two columns directly into the original TestTable formula to make it all happen in one step for use as a variable in the original Receipts table (otherwise I end up with circular logic if I try using relationships).
I've tried the following:
TestTable = SUMMARIZE(PPTs, PPTs[Month], "TotalReceiptsIssuedInThisMonth", SUM(PPTs[PPTs Issued]), "OccurenceOfMonth", COUNT(PPTs[Month]), "TotalReceiptsIssued", SUM(TestTable[TotalReceiptsIssuedInThisMonth]), "AvgPercentageReceiptsIssuedInThisMonth", TestTable[TotalReceiptsIssuedInThisMonth]/TestTable[TotalReceiptsIssued])
but this returns an error saying "A single value for column 'TotalReceiptsIssuedInThisMonth' in table 'TestTable" cannot be determined. This can happen when a measure formula refers to a column that contains many values without specifying an aggregation such as min, max, count, or sum to get a single result." and I've tried:
TestTable =
VAR first = SUMMARIZE(Receipts, Receipts[Month], "TotalReceiptsIssuedInThisMonth", SUM(Receipts[Receipts Issued]), "OccurenceOfMonth", COUNT(Receipts[Month]))
VAR second = SUM(TestTable[TotalReceiptsIssuedInThisMonth])
VAR third = first[TotalReceiptsIssuedInThisMonth]/second
RETURN
third
But this returns an error saying "The variable'first' cannot be used in current context because a base table is expected."
So my question is, how do I go about combining these three steps into one DAX formula?
I would do something like this. I prefer ADDCOLLUMN(SUMMARIZE()...), because it helps to avoid a miscontexting. As you need a var table, then you need the CALCULATE in ADDCOLUMNS, as it adds the row context.
VAR TestTable =
ADDCOLUMNS(
SUMMARIZE(
Receipts
,Receipts[Month]
)
,"TotalReceiptsIssuedInThisMonth",CALCULATE(SUM(Receipts[Receipts Issued]))
,"OccurenceOfMonth", CALCULATE(COUNT(Receipts[Month]))
,"TotalReceiptsIssued ",SUM(Receipts[Receipts Issued])
)
RETURN
ADDCOLUMNS(
TestTable
,"AvgPercentageReceiptsIssuedInThisMonth"
,DIVIDE([TotalReceiptsIssuedInThisMonth],[TotalReceiptsIssued])
)

The Films table looks like this
There is a ComfortBreaks table looking like image
In the Films table I need to create a calculated column called NumberBreaks which shows for each film the number of breaks needed. To do this I have to pick out the value of the Breaks column where:
The value of the lower limit in the ComfortBreaks table is less than or equal to this film's running time in minutes
and
The value of the upper limit in the ComfortBreaks table is greater than this film's running time in minutes.
the result should look like the image below
There cannot be a relationship between the two tables. so this has to be done without creating relationship between them.
I tried lookup function but it showed error:A table of multiple values was supplied where a single value was expected.
You can use this below code for your custom column. Considering
number_of_breaks =
VAR current_row_run_time_minutes = Films[RunTimeMinutes]
RETURN
MINX (
FILTER(
ComfortBreaks,
ComfortBreaks[LowerLimit] <= current_row_run_time_minutes
&& ComfortBreaks[UperLimit] > MonthNumber
),
ComfortBreaks[Breaks]
)
You can perform your further average calculation on the new custom column now.
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 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.
