It is my first time I use Tableau Server, I added a scheduled extract, but it failed and I got this message:
I tried to refresh it manually and yet it still failed.
And in the publish page I tried to modify the option of managing the data sources but I didn't have it here: (below picture)
I would appreciate any help guys and thanks in advance,
