How to Sum the total in a view, even with date filter

Hi! I would like to know how to sum the total in a specific view even with date filters.

It should to sum (and show) $390.800 in a row called Total Sum, even with date filters. I don’t know how to this. Can you help me with some idea. Like Formula or some hint?

No sum formula needed. Just add a new column with a common value to all rows, then group by this column in the view.

How a common value? can you explain details? I’m new

Please post a screenshot of your table. Thanks.
