Sum up key figures in cube

Question

Hi,
I would like to include an ABAP code in a start routine.
My infocube contains account numbers.  for each account there is an amount (0QUANTITY) and a 0CALMONTH.  Each line in the cube contains an account number and a 0CALMONTH.
On every line of my infocube (for every account number with its 0CALMONTH) I would like to calculate in a new column the total amount for a duration of a roll back year.  Ex: Account Number 123, 0CALMONTH = 01/2009, 0QUANTITY = 10 -> In the new colomn I want the sum of 0QUANTITY for a roll back year (0QUANTITY 01/2009 + 0QUANTITY 12/2008 + 0QUANTITY 11/2008 + ... + 0QUANTITY 02/2008).
Can someone give me an example of the ABAP code to perform this?
Thanks a lot!

When applying the solution you describe, beware of the modification on the different axis you use in your query.
For instance, if the characteristic owner is linked to the characteristic Account, and if it can changed, you can encounter some difficulties to consolidate your data:
On January :
  Account N° 123 Owner 001 -> 0CALMONTH 01/2009 -> Quantity 10
  Account N° 123 Owner 001-> 0CALMONTH 02/2009 -> Quantity 10
On February :
  Account N° 123 Owner 002 -> 0CALMONTH 02/2009 -> Quantity 20
  Account N° 123 Owner 002-> 0CALMONTH 03/2009 -> Quantity 20
Here, data on february are assigned to the owner 1 and 2 (for the same account), this is not what you necessarily want...
The problem is that you assign values in the future (and here, you don't know which owner will be assigned to the account in this future)...
