I have added a Microsft SQL Server 2018 Stored Procedure as Data Source in Tableau Desktop 10.5.
From the "Data Source" screen I would like to select Data => "Convert to Custom SQL" but is unselectable.
Why I can't select this field?
I am trying to follow this tutorial so I need to pass from this point.
PS: I have tryed with a SQL Server 2012 SP but the menu is unselectable too.
Drag any tables and select data menu and see convert to custom sql option enabled.
