Just realize today that I can actually download the whole OLAP cube and browse with Excel 2007 when you offline. Below are the steps:
1. Access the .ODC file online
2. When you click Open, you will fire up Excel and the Pivot Table Field List.

Construct you Excel Pivot Table view. For example I put Reason on Row Labels, Calendar Year, Quarter and Month on Column Labels and Incidents Count on Values.

To take the cube offline, click on Options –> OLAP Tools –> Offline OLAP
Because you don’t have a Offline data file, on the Offline OLAP Settings window you will see Offline OLAP option is grayed out. Create the data file by click on Create Offline Data File.

You will be presented by a wizard, click Next on the first screen
Because a real life data warehouse is huge and you might not want every data, you can choose the level of field you want to store in the offline data file. Then click Next.

Then specify the item within the level and click Next.
Finally specify where you want to store the data file and click Finish
Now you see Offline OLAP option is enabled.
