I am running reporting server integrated into SharePoint (MOSS2007) and have several reports already designed (in Visual Studio 2008), published to a SharePoint Library and subject to subscriptions and I need to output these subscriptions as xlsx and not xls as they currently are.
My Query
How do I
a. Make the new rendering options available on my existing reports from within visual studio so I can then publish them to the SharePoint library and then use the new rendering extensions in my subscriptions , or
b. Publish the reports after revision in Xl to the SharePoint document library?
After going round the houses in your documentation I cannot find an answer, I cannot even see if you support reporting services in SharePoint integrated mode. Any help gratefully received
