If you have spent any time watching SharePoint videos on YouTube or elsewhere you may have noticed that there are many that demonstrate the rich feature set of SharePoint and few that actually show you how to get anything done. This is too bad because sometimes I think SharePoint administration is more difficult than creating PowerPivot data models.
Bucking this unfortunate trend is Melissa Coates of SQLChick who has produced a video about creating Power BI report libraries in SharePoint 365. Admittedly, one doesn’t usually need to create libraries until he has already created many reports, but watching Melissa administer SharePoint while giving a clear explanation of what she is doing has been very helpful in advancing my overall understanding of the system. The video can be found here: http://msbiacademy.com/?p=7531 . I recommend watching even if, especially if, you don’t know why you might want to use report libraries at all.
