We don't actually ever sort the underlying data in Tableau, we only sort the display of the underlying data. If you always want the data to come out of the data source in a certain order, then you need to define that order in the data source (which may not always be possible). Depending on your desired results, you may be able to create a text table view that has the desired sort.

I'm not clear on what you're referring to as sorting in descending order for underlying data.
Is it the ability to configure the sort order of data as shown in the image I'm providing here?
If so, as Jonathan points out, Tableau doesn't sort the underlying data, only the presentation of the data within
If not, where is it you're seeing Tableau Desktop perform sorting in descending order for underlying data?
I'm very curious, why is it you think Tableau is sorting the underlying data?
Which brings up the question: what is it you think the underlying data is?, or: what does "underlying data" mean to you?
I'm asking these questions because trying to identify places where it's not clear to people how Tableau works. Understanding these helps those of us involved with helping people learn and become productive with Tableau.
In Tableau today that view of underlying data cannot be manually sorted. For a view with sorted data, you'd need to create a text table in a Tableau worksheet and sort that.
I don't know where my brain went, what I wrote is not what I was thinking, you got it right, thanks!
