DS Cross tab dynamic measure

Hi,

Like in Webi can we create a variable in Design studio with calculated measures and this can inserted in cross tab to pull the values dynamically.

I have seen the document that global and local variables are created and used in Text button to display, this works fine for me too.

The same measure can we use to insert in cross tab to pull the values dynamically...like. .Actual Sales is a measure

                                         Jan                feb              march      Total Sales(3months Actual Jan feb March+9 Month forecasted sales data)

Region                                           

Europe                              50                  60                   70           ----

North America                   30                  52                   75          ------

Asia                                   85                  15                   65           --------

I would like to know total sales can be calculated using the above logic  in Design studio level and will this pull the data when you drop in the cross tab.

Thanks,

Ramesh.
