I cannot see the Salesforce work order object via the power query or power BI desktop connector. I can succesfully view and query many other objects but the work object does not appear in the power query navigator view (see screenshot). This article states that the work order object is supported by API version 36.0 and later so perhaps power query uses an earlier version?
However, if you have sufficient permissions on these standard objects in Salesforce, and you are not able to view all standard objects which are available in API version 36.0 or later, I agree with you, the Power BI Desktop may use earlier version of Salesforce API.
Thanks, Lydia Zhang
