Counting values back in time with a split in the Time dimension

Question

Hi there,
I would like to calculate how many sales months we had during the past half year. For every month in the past 6 months where there is sales > 0 this should be counted. On the account Sales Months I would like to see the result.
Lets say I had sales in 01 + 02 +03 + 05 but not on 04 and 06, the value on 07->Sales Months should be 4.
The seperated Years dimension makes it hard to calculate this for the first 6 months because the formula has to look back a year and the Months dimension is tagged as Time so I cannot use @PRIOR.
Maybe you guys have some great idea!
Regards,
Thijs

1. shutdown and backup your database (!!!).
2. start in umount mode
3. rman target sys/manager@EON1 catalog rman/rman@rman
4. at the RMAN prompt perform a point in time restore/recover, e.q.:
restore database until time "to_date('19.01.2009 13:00:00','DD.MM.YYYY HH24:MI:SS')";
recover database until time "to_date('19.01.2009 13:00:00','DD.MM.YYYY HH24:MI:SS')";
