I have a report with Order and Order Product fields in it. The Partner Communities user has read permission to both Order and Order Product and no problem viewing them outside of reports (eg: in a detail page). The user can also access various other reports (all in the same folder). However, when a user tries to access the report, the message "Data Not Available" is displayed. Similarly, if user tries to create a new report based on the report type for that report then no order product fields are shown (but they are when an internal user accesses the same report type). I have changed the sharing for Order from "same as parent" to "private" and defined relevant sharing rules but still no go. Any suggestions?

I think that the problem may be rooted in the same issue described in this question.
