Report based on 2 different Fact tables

Question

Hi all
Is it possible to make a report based on 2 Fact tables wich are not linked to exactly the same dimensions?
FactTable1 : linked to Time,Product,Geography
FactTable2: linked to only Time
The FactTable2 will contain only one measure which is a constant value per year and It will be used to be compared to the FactTable2's measure (It's a kind of reference).
So do FactTable2 need to be linked to Geography and product to be able to create this report??
Regards.

I tried to set the level for the metrics...now it doesn't make the CAST anymore, but i get a result set bigger than i need...
BI Server seems to make the union of 2 instead of the intersection...
For example, if i have 5 customers, but only 2 customers have a service request (order) associated, then the server returns the following report
Customer Code | Service Request Code | # asset(Fact 1) | # order (Fact2)
0000001_________NULL_______________ 5____________ 0
0000002_________NULL_______________ 4____________ 0
0000003_____ 700000930______________ 3___________ 1
0000004_____ 700000930______________ 3___________ 1
0000005_________NULL_______________ 3____________ 0
while my goal is to get just the list of customers having at least a service request (order)...
I tried to create a filter on the column "Serve Request Code", but it doen't have effect, cuz the server lunchs 2 different sql queries to create the report:
select D1.c3 as c1,
D1.c2 as c2,
D1.c1 as c3,
D1.c4 as c4
from
(select D1.c1 as c1,
D1.c2 as c2,
D1.c3 as c3,
D1.c4 as c4
from
(select count(distinct T111689.ROW_ID) as c1,
T112015.SR_NUM as c2,
T111844.OU_NUM as c3,
T111844.ROW_ID as c4,
ROW_NUMBER() OVER (PARTITION BY T111844.ROW_ID, T112015.SR_NUM ORDER BY T111844.ROW_ID ASC, T112015.SR_NUM ASC) as c5
from
CW_CASE T112015 /* Dim_CW_CASE_Case_Order */ ,
CW_CUSTOMER T111844 /* Dim_CW_CUSTOMER_Customer_Order */ ,
CW_ORDER T111689 /* Fact_CW_ORDER_Order */
where ( T111689.ACCNT_ID = T111844.ROW_ID and T111689.SR_ID = T112015.ROW_ID and T111844.ROW_ID = T112015.CST_OU_ID )
group by T111844.ROW_ID, T111844.OU_NUM, T112015.SR_NUM
) D1
where ( D1.c5 = 1 )
) D1
