Scheduling and embedding BO Reports in SharePoint

Hi,

We have a very restricted and locked down environment, so I am looking for some creative ways for scheduling and embedding BO Reports in
SharePoint. Goal is to publish weekly BO Reports, exported in Excel, to a document library on SharePoint, and/or to refresh embedded data in a SharePoint Web Part. Already tried scheduling to a SharePoint directory using UNC path, but it failed to access without giving a descriptive error message (Destination failed). A third party software, or direct connection to SAP is out of the question per our Administrators (performance, security, etc.). Looking to hear from anyone who had similar challenges and has come up with a “home-grown” solution.

Thanks kindly.
