Aggregate amount - Content tab

Question

Hello,
In my repository, I have 2 stars schemas joined by a common dimension.
Fact1 <- Dim_F1
Dim_Common
Fact2 <- Dim_F2
Everything is OK concerning the filling of the content tabs for logical table source and for the aggregate amount according to the dimension hierarchies for Dim_F1, Dim_F2 and Dim_Common. So, when I query :
Dim_F1.val1, Fact1.amount_sum2, Dim_Common.val2, Fact2.amount_sum2, Dim_F2.val3
the result is coherent.
But if I only query
Dim_F2.val3, Fact2.amount_sum2
or only Fact2.amount_sum2
the result is aggregated according to the content tab of the logical column Fact2.amount_sum2.
So instead having only one amount, I have many lines as OBIEE execute :
select c3 from (
select id_common c1, id_dim_F2 c2, sum(amount_sum2) c3
from ...
where ...
group by id_common, id_dim_F2)
Is this mean, that I have to create 2 amount_sum in my Fact2 table ? One to use when I want to see the Fact2.amount with the Fact1.amount and another one when I only take fields from the star schema in which Fact2 is ?
I'm completely lost and I really would like to understand this point so if my post is not clear don't hesitate to tell me.
Another point, is there a mean to fill the content tabs of a logical columns automatically according to the content tab of a logical table source ?
Thanks in advance for your help.

Thank you for your reply Wildmight but I have tried to put an implicit fact on an amount of Fact2, but I continue to have my problem :
If I query only Fact2.amount_sum2, then the generated SQL is :
select D1.c1 as c1
from
(select sum(T23105.MTINIT_TBE) as c1,
T22952.ID_RT as c2,
T23089.ID_TS as c3,
T23105.ID_TS as c4
from
Dim_F2 T23089,
Dim_Common T22952,
Fact2 T23105
where ( T22952.ID_RT = T23105.ID_RT and T23089.ID_TS = T23105.ID_TS )
group by T22952.ID_RT, T23089.ID_TS, T23105.ID_TS
) D1
and the results is
10
20
25
But what I want if I only query an amount is 55.
Do you have another idea ?
Thanks in advance.
