# Filtering for dates even though I used ALL(Dates) function

Hello, I am working on " Understanding how variables are evaluated" in Mastering DAX Calculations course. In this video Sam explain if we add ALL function around Dates table ( ALL(Dates)) result would not change even we change the filter context using date column.

``````Customer Sales of Top Products =
CALCULATE (
[Total Sales],
FILTER ( Products, CALCULATE ( [Total Sales], ALL ( Dates ) ) > 100000 )
``````

)
But if we change the date ( by date column as a filter) it is changing. Can someone explain what is happening in this calculation.
Thank you!

@akila789 I am assuming the below screenshot would be difficult to comprehend for you, but it shows how your code works.

See if this works:

``````Customer Sales of Top Products =
CALCULATE (
[Total Sales],
FILTER ( Products, CALCULATE ( [Total Sales], ALL ( Dates ) ) > 100000 ),
REMOVEFILTERS ( Dates )
)``````

Answer is helpful. Anyway I figured out what happens after I post this question.
What is happening is it calculates [Total Sales] of products where if that productâ€™s [Total Sales] > 100000 without regarding the time. So, when ever [Total Sales] is less even from the beginning of time does not include for calculate final [Total Sales] measure.
