DAX Calculate with Filter

Anonymous — Fri, 14 Jan 2022 09:55:24 GMT

Hi there,

I have a sales data table as below. Each customer has more than 1 contract.

I want to calculate the total sales between the latest contract date for each customer and up to 31 Dec 2021. The result i am expecting is the yellow cells below and the total should be $1490 (1300+100+90).

Dax:

1. Latest Contract Start Date = max(Sales[Contract Date])

2. Total Sales from Latest Contract Start to end of Dec 2021 = CALCULATE([Total Sales],DATESBETWEEN('Calendar'[Date],[Latest Contract Start Date], date (2021,12,31)))

Below is the PowerBI result. at customer level, it is showing correct calculation. However, at total level, the $90 total sales is wrong as it is picking up the latest contract start date from the full list. How should i change the formula so that at total level, it will show as $1490?

Thank you!!

Hi,

Total calculation uses the same logic as the formula in the column it is in. You can create an IF logic to change this. E.g. Example = IF(ISBLANK(SELECTEDVALUE('Table'[Customer])),[Total sales],
CALCULATE([Total Sales],DATESBETWEEN('Calendar'[Date],[Latest Contract Start Date], date (2021,12,31)))
)

The point here is to change the calculation logic when we are calculating total.

I hope this post helps to solve your issue and if it does consider accepting it as a solution and giving the post a thumbs up!

Hi ValtteriN

Thanks for your advise.

However, the formula will still arrive at wrong amount.

The total amount should be the sum of all the lines above, which is total of $1490 (1300+100+90). The total should calculate each of the customers' sales at their respective latest contract start date.

Thank you!

Hi,

You can use this pattern to get the value for last sales date =

LastDaySales =

var _date = MAX('Calendar'[Date])

Var _lastSalesDate = CALCULATE(max(Sales[Date]),all('Calendar'),Sales[Date]<=_date) return

sumx(Sales,CALCULATE(SUM(Sales[Amount]),Sales[Date]=_lastSalesDate))

This should get the desired end result:

Anonymous can you try this

Measure = CALCULATE ( [Total Sales], FILTER ( Sales, Sales[Contract Date] >= CALCULATE ( MAX ( Sales[Contract Date] ), ALLEXCEPT ( Sales, Sales[Customer] ) ) && Sales[Contract Date] <= DATE ( 2021, 12, 31 ) ) )

Hi smpa01

Thank you for your advise. It works!!

I tried to apply the same concept to a very simple scenario below but i couldn't seem to get the desired result.

I have Customer A and B purchased cars from me. Due to certain reason, Customer A signed 3 different contracts but the total cars purchased by Customer A was 200,000 (#A001+#A002+#A003). Customer B purchased 800 cars. Hence, in total, i have sold 200,800 cars.

Excel:

DAX:

Total Cars Purchased =

CALCULATE (max('Car Purchased'[Cars Purchased]), ALLEXCEPT('Car Purchased','Car Purchased'[Customer]))

How should i amend the formula so that the total in Power BI will show 200,800 instead of 200,000? I am not sure what i did wrong here...

Thank you!!

Anonymous try this

Measure = SUMX ( VALUES ( 'Table'[Customer] ), CALCULATE ( MAX ( 'Table'[Car Purchased] ), ALLEXCEPT ( 'Table', 'Table'[Customer] ) ) )

hi smpa01

It works again!! i applied the logic to some other calculations in my dashboard and it all worked!

Thank you so much for your help!! You have just made the world a little better 😁

Cheers!
