I had a problem with my code. It returns the below error:
DAX comparison operates do not support comparing values of type date with values of type text.
Basically, I want to count rows based on some conditions. And I know there is a need to convert the data type, but I am not sure how to do it.
Total Open Issues =

--basic info
VAR SELECTEDDATE =
DATEVALUE(SELECTEDVALUE(Calender[FullDateAlternateKey].[Date]))

VAR rlvttable =
calculatetable(
Tracker,
Tracker[Catagory]="ISSUE",
DATEVALUE(Tracker[ClosedDate])>SELECTEDDATE
||Tracker[ClosedDate]=""
)

Return
countrows(rlvttable)
Anyone could advise me how to correct it? Thanks~
Check the data type of columns Tracker[ClosedDate] and Calender[FullDateAlternateKey] - one of them is Text, rather than Date.
To fix, you could:
choose a different field which is already a Date format
change the format of the offending column
use DATEVALUE in your measure, to convert the text date to a real date.
It also looks like you need to edit this statement, as these conditions conflict:
Tracker[ClosedDate]>SELECTEDDATE
&&Tracker[ClosedDate]=""
I am trying to compare the closedDate with "". I should use blank() instead.

I have created a measure using a SWITCH function that changes the format of the data from currency to percentage based on a measure slicer. See the DAX code below. This works great, but the problem is I want to be able to sort the measures still, but they are sorting as text instead of numbers.
Month End MTD Variance = var _sales= CALCULATE([YTD Max Value] - [YTD Min Value]) return FORMAT(_sales, SWITCH( SELECTEDVALUE(Category[Category],"Sales"), "Sales","Currency", "Quota","$#,##0", "PTQ","#,##0.0##%" ) )
Don't use a switch statement to do this. Use the inbuilt feature for Field Parameters. Create two separate measures formatted accordingly, add them to the field parameter. Use the value of the field parameter in your table and slicer to switch and the formatting will carry across automatically.
I want to use the selected slicer value in string format to filter rows in a table in a visual.
So, I created the following measure:
SlicerVal = ALLSELECTED(Table[Column1])
The follow up measure is as follows:
TotalRows = CALCULATE(COUNTROWS(Table),filter(Table, Table[Column2] = [SlicerVal]))
However.. This returns completely different data. When hardcoding the string value the correct data is returned, like in the example below:
TotalRows = CALCULATE(COUNTROWS(Table),filter(Table, Table[Column2] = "A"))
Is there a way to convert the measure value to a string somehow, which can be used dynamically to correspond the string value filter to the selected slicer value?
How about this?
TotalRows = CALCULATE(COUNTROWS(Table),filter(Table, Table[Column2] IN ALLSELECTED(Table[Column1])))
[Question: are you intentionally filtering on all selected elements from Column1 when applying a conditions onto Column2? I have no idea about your use-case, that's why -- for safety reasons -- I'm asking...]
I am creating a dashboard in Power BI. I have to report the executions of a process in a daily basis. When selecting one of these days, I want to create another calculated table based on the day selected (providing concrete information about the number of executions and hours) as it follows:
TABLE_B = FILTER(TABLE_A; TABLE_A[EXEC_DATE] = [dateSelected])
When [dateSelected] is previously calculated from the selected day as it follows:
dateSelected = FORMAT(FIRSTDATE(TABLE_A[EXEC_DATE]);"dd/MM/yyyy")
I tried a lot of alternatives as, for example, create individualy the year, month and day to later compare. I used the format in both sides of the comparation, but none of them works for me. The most of the cases it returns me the whole source table without any kind of filters. In other cases, it doesn't return anything. But, when I put a concrete day ...
TABLE_B = FILTER(TABLE_A; TABLE_A[EXEC_DATE] = "20/02/2019")
... it makes the filter correctly generating the table as I want.
Does someone know how to implement the functionality I am searching for?
Thanks in advance.
You're almost there Juan. You simply need to use dateSelected as a varialbe inside of your DAX query:
TABLE_B =
var dateSelected = FIRSTDATE(TABLE_A[EXEC_DATE])
return
FILTER(TABLE_A, TABLE_A[EXEC_DATE] = dateSelected)
Note that all my dates are formatted as Date so I didn't need to use a FORMAT function.
Here's the final result:
I admit that this behavior can be quite confusing! Here is a useful link that will help you understand Power BI's context:
https://community.powerbi.com/t5/Desktop/Filtering-table-by-measures/td-p/131361
Let's treat option 1 as FILTER(TABLE_A; TABLE_A[EXEC_DATE] = "20/02/2019") and option 2 as FILTER(TABLE_A; TABLE_A[EXEC_DATE] = [dateSelected]). Quote from the post:
In option 1, in the filter function, you are iterating
over each row of your 'Table' (row context). In option 2, because you
are using a measure as part of the filter condition, this row context
is transformed into an equivalent filter context (context transition).
Using variables (...) is very convenient when you want to filter
a column based on the value of a measure but you don't want context
transition to apply.
I am new to power BI and stuck with an issue. I have my model as follows:
Date Dimension
Measurement Fact
The date column in Date Dimension is link to measuredate in Measurement Fact
Below is a sample data:
NB: In edit query, I have changed the type of measuredate to Date only.
I have tried the measure below but it doesn't work the way I want. It will sum all the values of the day but what I want is the last value of the day:
day_fuel_consumption =
CALCULATE (
SUM ( measurement[measurementvalue] ),
FILTER (
measurement,
measurement[metername] = "C-FUEL"
&& measurement[measuredate] = MAX ( measurement[measuredate] )
)
)
My Goal is to get 29242, i.e the last value of the day. Remember that measuredate is a Date field and not Datetime (I changed to Date field so that my Year and Month filter can work correctly). I have changed the type in edit query.
Changing your measure to use a variable could be the solution:
DFC =
var maxDate = MAX(measurement[measuredate])
return
CALCULATE(
SUM(measurement[measurementvalue]),
measurement[measuredate] = maxDate
)
However, you should keep the datetime format for measureDate. If you don't want to see the time stamp just change the format I power bi. Otherwise power bi will see two values with max date and sum them, instead of taking the last one.
Well, if you want to avoid creating a measure, you could drag the fields you are filtering over to the visual filters pane. Click your visual, and scroll a tiny bit and you will see the section I am referring to. From there, just drag the field you are trying to filter In this case, your value. Then select "Top N". It will allow you to select a top (number) or bottom (number) based on another field. Strange enough, it does allow you to do top value by top value. It doesn't make sense when you say it out loud, but it works all the same.
This will show you the top values for whatever value field you are trying to use. As an added bonus, you can show how little or how many you want, on the fly.
As far as DAX goes, I'm afraid I am a little DAX illiterate compared to some other folks that may be able to help you.
I had to create two separate measures as shown below for this to work as I wanted:
max_measurement_id_cf = CALCULATE(MAX(measurement[measurementid]), FILTER(measurement, measurement[metername] = "C-FUEL"))
DFC =
var max_id_cf = [max_measurement_id_cf]
return
CALCULATE(SUM(measurement[measurementvalue]), measurement[measurementid] = max_id_cf)
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.
