PBI won't connect to SQL Server table

hi community,  I'm new to PBI and I either I'm missing something fundamental or this thing is really buggy.  I can't even connect to a SQL Server 2008 table.   As I try and connect to the table it says the column can't be found. 

Here's the script fro mthe advanced editor

let
    Source = Sql.Databases("qlikview.dk.sql.group.icopal.git"),
    IproBis = Source{[Name="IproBis"]}[Data],
    dbo_SA_CUSTOMER = IproBis{[Schema="dbo",Item="SA_CUSTOMER"]}[Data]
in
    dbo_SA_CUSTOMER

I've tried it for a single field but I get the same error.  Some help would be appreciated. 

Thanks in advance

Mark
