DAX help on filter context

Anonymous — Wed, 23 Nov 2022 14:37:30 GMT

Hi Team,

Please can you help me on below requirement.

I have Table A with below fields

Name Date Amount

A 2022/11/23 10

A 2022/12/20 20

A 2022/11/23 30

1. From above table how to create two Date filters from one Date field like below

2. Once Dates are filtered like above how to calculate the below measure. In measure the dates should change dynamically based on user selections.

Amount =

CASE WHEN (DATE1 >= '2022-11-21 00:00' AND DATE2 <'2022-11-22 00:00' ) THEN AMOUNT
ELSE 0
END

Please help me to write the above dax

Hi,

First I think you should create 2 variables for your dates.

And to "grab" the value from your slicers, could you use MIN and MAX ? It should return what you expect otheriwse give us more details on your project.

Then compare :

VarDate1 >= DATE( 2022 , 11 , 21 ) && VarDate2 < DATE( 2022, 1, 22 )

For dates you should use date function, and for the AND you can use &&, or when you need OR ||.

Let us know first if it works with MIN and MAX before getting into the details of IF test, if needed 😉

Hi AilleryO Thanks for your reply. Actually Date 1 and Date 2 fields are from two different tables. Table B is created from Table A like Table B = DISTINCT('Table A'[Date 1])

Sample data:

NameDate 1 Amount

A	23/11/2021	10
A	20/12/2021	20
A	23/11/2022	30
B	15/10/2021	10
B	15/10/2022	70

Requirement is between Date 1 and Date 2 range what is the total amount by name.

I have created variables like below . But how to write return statement like

if(Table A[Date1]>= Date1 &&Table B[Date2]< Date2,Amount,0) -- It''s throwing error

Hi , Anonymous

According to your description, you want to calcuate the sum of [Amount] per name and between the two date in the slicer visual.

If this , i think you do not need to create another date table, you just need to put the 'Table A' [Date] in the visual and then you can get the data, like this:

If this method does not meet your needs, you can provide us with your special sample data and the desired output sample data in the form of tables, so that we can better help you solve the problem.

Thank you for your time and sharing, and thank you for your support and understanding of PowerBI!

Hi v-yueyunzh-msft Thanks for your reply. The above solution is not working. please find the below expected output

Input Table:

Name Date 1 Amount

A	23/11/2021	10
A	20/12/2021	20
A	23/11/2022	30
B	15/10/2021	10
B	15/10/2022	70

output: for Date 1 = 23/11/2021 and Date 2 = 23/11/2022 selection

Name Amount

A 30

Amount calculation: i am lookinf for dynamic dax expression for below calculation as user can select any of the dates

CASE WHEN (DATE1 >= '2022-11-21 00:00' AND DATE2 < '2022-11-22 00:00' ) THEN AMOUNT
ELSE 0
END

by using date range i am getting amount for A=60 instead of 30 because its taking date 1 >= selected date and date2<=selected date. It should be date 1 >= selected date and date2< selected date.

According to your description , you want to “CASE WHEN (DATE1 >= '2022-11-21 00:00' AND DATE2 < '2022-11-22 00:00' ) THEN AMOUNT”.

Here are the steps you can refer to:

(1)My test data is the same as yours.

(2)For your need , i recommend you to create a date table as slicer instead of using the date column in your table. You can click “New Table” and enter this:

Date = CALENDAR( FIRSTDATE('Table'[Date1]),LASTDATE('Table'[Date1]))

And we do not need to create relationship between two tables.

(3)We can click “New Measure” to create a measure:

Measure = var _min = MIN('Date'[Date]) var _max = MAX('Date'[Date]) var _t =FILTER('Table' , 'Table'[Date1]>= _min && 'Table'[Date1] <_max) return SUMX(_t,[Amount])

(4)Then we can put the ’Date‘[Date] on the sliver visual and the [Name] and the measure on the visual and we will meet your need :
