OBIEE 11.1.1.6 Help needed to resolve a user requirement for an analysis

Question

Hi all,
I need to create a pivot table like this:
Show a calculated measure VALUE / QUANTITY by dimension1 (on rows) and year & month (on columns). Add a grand total on year. Add a calculated item that shows the difference between grand total on year and last month shown. That is:
----------2012-------------------------------------------------------------+
----------JANUARY---FEBRUARY--MARCH-----APRIL-----Total 2012+Diff------+
+ (dim1) + 205+ 212+ 209+ 211+ 210+ 1+
Obviously it's easy to do if I don't take the additional calculated item into account.
But when it comes for having it specified, I'm in trouble:
I can put year and month on columns and create a total on year (and it works) but I don't know how to create the diff calculated item...
or...
I can create two calculated items, one for the grand total (but I don't exactly know how to define the rule), the other one defined as LAST month - grand total (but I get an error if I try to use a calculated item in a calculated item).
Any help or suggestion is welcome.
Version is 11.1.1.6.
Thanks!
Cristina
