Group Date in Report Studio

[cognoid1]

My data contain four dates (03/2/2006, 03/09/2006,03/16/2006 and 03/23/2006).  When i generated the report, i ended up with 4 columns in the crosstab which is ok.  However, my customer want only ONE column showing March 2006 for all 4 dates.

How do I accomplish this in Report Studio?

thanks

Gget rid of the days and make it Month-Year instead.
