Filter table based on dates from another table

Hi , Anonymous 

Thanks for your sample data first!

According to your description, you want to filter the table by the slicer .

Here are the steps you can refer to :
(1)This is my test data:

(2)We can create a measure like this:

Measure = var _start_date = MAX('Table1'[start_date])
var _end_date = MAX('Table1'[end_date])
var _t = FILTER('Table2','Table2'[date]>=_start_date && 'Table2'[date]<=_end_date)
return
SUMX(_t,[sales])

(3)Then we can put the fields we need on the visual and the result is as follows:

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. (You can also upload you sample .pbix [without sensitive data] to the OneDrive and share with the OneDrive link to me ! )

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

Best Regards,
