We're using SQL Server 2012 SP2 and SharePoint 2013, and have started experiencing a strange error:
One of the workbooks, which connects to an Oracle 11g database, has started generating new tables in the PowerPivot data model on refreshes. The refresh says it fails, "Excel services returned an error", but I opened up the workbook to find a dozen
tables named, "Query1", "Query2", "Query3" etc.

Has anyone else run into this, or have a fix? Does Cumulative Update #1 address it? I don't administer the server, but I should be able to get answers quickly if any additional information is needed.
Thanks
