When publishing Excel Workbooks that contains PowerPivot objects, a real Analysis Services cube is generated on the fly, you don’t believe me?
1. Install the PowerPivot Add-in for Excel 2010 and use it to create a workbook.
2. Publish the workbook to a document library which is marked as a trusted data source (Unlike MOSS 2007, All SharePoint sources are trusted by default in SharePoint 2010 as shown below).
3. Open SQL Server Management Studio, click Connect > Analysis Services and type the URL of the workbook you just published and click Connect.
Interesting, eh ?

Yesterday, while presenting about Business Intelligence using SharePoint 2010 Excel Services, we came across the data validation limitation. NOTE: Excel Access Web Part refuses to load a published Excel workbook that contains Data Validation.
Here are couple of interesting articles that are worth reading:

2) Unsupported Features in Excel Services
As shown in the screenshot below, I was trying to consume data from SQL Server Analysis Services cube using Excel 2010 Pivot Table.
Refreshing and filtering data worked as expected on the client but when I published my workbook to Excel Services, filtering and slicing produced the following error
“The data connection uses Windows Authentication and Excel Services is unable to delegate user credentials.”
Of course, the workbook existed in a trusted location and the external data connection file resided in a trusted connection library.
To solve this issue, I navigated to the Central Administration and started “Claims to Windows Token services” as shown below :
This allowed me to refresh data using Windows Authentication…
Excel Services supports displaying data from external locations if those locations were configured as “Trusted”. Try creating a simple excel document with a Table that displays data from a SQL server table . Now try to view it in Excel Web Access. You will get the following error:
After some investigations, I found out that Excel services supports displaying data from external data sources, but not in a table format, only in a pivot table!
To work around this limitation, you need to convert your tables to pivot ones? How ? Download this tool and you are good to go !

esterday, I was playing with Excel Services on an old MOSS 2007 VM that has no network. When publishing an Excel Spreadsheet to Excel Services, I received the following error:
“Microsoft Office Excel This file cannot be saved to this location because there is no connection to the server. Check your network connection and try again. ”
After some quick research, I found out that this problem is related to the System Event Notification Service. To work around this issue, I ran net stop sens from the command line.
