With 'SQL Server Reporting Services - Native' installed, attempting to edit an Excel Report in GP 2013 R2 gives an unusual error, as follows:
System.Web.Services.Protocols.SoapException: The path of the item '/\\craig-win8lap\GPShare\GPData\Excel Reports\Reports\TWO\Sales\TWO SalesTransactions This Week's Returns.xlsx' is not valid. The full path must be less than 260 characters long; other restrictions apply. If the report server is in native mode, the path must start with slash. ---> Microsoft.ReportingServices.Diagnostics.Utilities.InvalidItemPathException: The path of the item '/\\craig-win8lap\GPShare\GPData\Excel Reports\Reports\TWO\Sales\TWO SalesTransactions This Week's Returns.xlsx' is not valid. The full path must be less than 260 characters long; other restrictions apply. If the report server is in native mode, the path must start with slash.

=========================
Not sure what is going on. The feature report for SQL Server 2012 shows SSRS-Native. The reports deployment seemed to go OK, and I actually re-ran it for excel reports to be sure, but then got this error again when I attempted to edit an excel report. Interestingly, editing an SRS report is fine. Anyone seen this, or have any ideas? Thanks in advance for any help you can provide.
