Problem querying over two fact tables

Question

The business requirement is that we want to be able to see sales for two different periods of times, over different brands, different Items' years and seasons per periods.
So for the different dimensions I created alias having two tables in the physical layer
for Brands, Shops and Items (tables) [These are the tables where I query for different brand, Item's year and different season]. The Business Model Schema looks like this:
Items-----> SALES <------Brands Items 2-----> SALES 2 <------------Brands 2
^ ^
TIMES TIMES 2 (TIMES JOINED WITH SALES AND TIMES 2 WITH SALES 2)
and VENDORS connected to both SALES & SALES 2 left outer joined
The need is that I need to query over two indepedent periods of time with independed dimensions but for a common dimension (Vendors).
The presentation data simplified looks like this:
Answers
Vendor Sales Qty Sales 2 Qty
1092 234 123
The problem is that when a vendor doesn't exist in one period it doesn't come and in the other although there are sales. So when I query with the same filters (same period of time, Brands, Items' years and seasons) over these two fact tables I get the same sales and correct data. When there are different criteria then I lose data.
The Query fired in the database is the following:
select distinct case when D2.c4 is not null then D2.c4 when D1.c4 is not null then D1.c4 end as c1,
D1.c3 as c4,
D1.c1 as c5,
D1.c2 as c6,
cast(D1.c2 / nullif( D1.c1, 0) * 100 as DOUBLE PRECISION ) as c7,
D2.c3 as c8,
D2.c1 as c9,
D2.c2 as c10,
cast(D2.c2 / nullif( D2.c1, 0) * 100 as DOUBLE PRECISION ) as c11
from
