WEBi relies on ODWEK to access the content - if ODWEK fails to retrieve the content, then WEBi will not be able to view the content
The ODWEK has to be on the same machine as WEBi
If WEBi is having a problem:
1. first use the OD Client for Windows to retrieve the report
2. if that is successful, then run an ODWEK sample that retrieves the same report - if the report retrieval succeeds, then the problem is localized to WEBi
