SUM...OVER... in OWB mappings

Question

Hello,
I need to implement the following phrase in OWB mappings, how would I do it?
select lot, pdate, sum(rec_amount) over (order by pdate rows between unbounded preceding and current row) from S1;
Where S1 is the result of a set operator.
Thank you,
GH

Hi,
Thanks for the quick reply oleg. I got the sum()..over() clause working thanks to your screenshot. However, i got a little side problem here. The sum()..over() clause should take data in this form (product sales table)
PRODUCT 01/01 01/02 01/03 01/04 01/05
A 100 200 (null) 100 (null)
B 50 (null) 100 (null) 10
and turn it into something like
Product 01/01 01/02 01/03 01/04 01/05
A 100 300 300(*) 400 400(*)
B 50 50(*) 150 150(*) 160
The numbers in the above table that were attached to a (*) were not generated, however, since on those dates, no transaction occurred for such product. I need to have these days since the result of such table will be mapped to a MOLAP cube. If such number doesn't exist in the tables, it certainly won't exist in the MOLAP cubes, (right?) unless there are some procedures or functions that can automatically fill in those with (*) in the cube or elsewhere.
Please advise on this,
GH
