Connecting to SharePoint drops internal/hidden columns

[lnkh]

I am trying to get Alteryx to read from a SharePoint (2013) list. The list is configured to have approval ("require content approval for submitted item" = yes).  When approval is turned on SP automatically creates the column called "Approval Status" to track. 

The "Approval Status" column is not getting pulled into my workflow. I need to pull in this field and also update it via Alteryx. I am pulling from a view that displays the Approval Status column.  I've seen another post about missing columns being related to modifying the list, but i have not modified any columns in this list. 

Tableau and Power BI has configuration to pull "hidden columns" like the Approval status. It is a hidden column because it is not listed in List Setting where you can add/edit columns. 

Any idea how to get this to work?

Thanks!
