Compatibility with Office 2007

Hi,

where can I find more information regarding the compatibility of BEx 3.5 and 7.0 (both running on BI 7.0 plattform) as well as BPS planning? Is Office 2007 fully compatible and supported? I noticed that there are many threads here regarding several functions not working correctly with e.g. Excel 2007.

I would need a kind of official document from SAP.

Thanks!
