In the Studio, open your "Salesforce with SSO" type data source. In the Connections tab, look for the drop-down field for "Filter Scope". When the data source was initially created, it may have defaulted to: "Delegated" after the introspection was completed and saved.
Change the "Filter Scope" setting to "Everything" and save it in the Studio, then retry your query.
These are the normally allowable values: - Delegated - Everything - Mine - MineAndMyGroups - My_Territory - My_Team_Territory - Team
