Avanced tab in Power Pivot windows 'Excel 2013)

Hello,

I'm studying Power Pivot and Power View in Excel 2013. I'm working on this exercise:

http://office.microsoft.com/en-us/excel-help/tutorial-extend-data-model-relationships-using-excel-2013-power-pivot-and-dax-HA104074532.aspx?CTT=5&origin=HA104073811

In the Power Pivot windows we are supposed to find a Advanced tab. But I don't have this Advanced tab.

What did I missed ?

Thanks for your help

and
