How to set a default value for a parameter - Fromperiod 7 ToPeriod from script

I have two parameters called FromPeriod & ToPeriod of type String. It
is actually a parameter for a dimension calendarYearMonth.
The default value of ToPeriod I want is 2006009 for the current month
which is Sept 2006 and I want FromPeriod to be 2005009 which is current
date - 365.
I want the default value to be derived from the current system date and
assign the current year and current month concatenated together to
FromPeriod & ToPeriod
Appreciate if you could kindly share the approach to implement this.
Thanks
KarenCreate a new dataset which can either select the current system date using
getDate() or can calculate the full text string you are after based on
getDate().
In the parameters window reached through the report menu, set the default
value to derive from query and reference the new dataset there.
Hope that helped.
