SQL Server Reporting Services SSRS Report Builder GUID Error – Item Not Found

Using Report Builder 3.0, SharePoint Integrated Mode and SQL Server 2008R2.

On creating a new report in Report Builder, I kept getting the error:

‘Failed to preview the report. The Item XXX can not be found’.

XXX being a meaningless GUID.

Turns out, the Report needed to be saved to a SharePoint library for the preview to render.

Lean something new every day:

The Fix, thank you Technet:

Save to a SharePoint Library!
