OBIEE: Incorrectly defined logical table source doesn't contain mapping

Question

In OBIEE 10.1.3.2 I have a very simple thing but cannot get it to work. Hopefully someone can point out the mistake. I have the same schema on two different database that I want to compare data.
The schema is simple. Table (dimension) A has two columns: id and name. Table (Fact) B has two columns: id and value. Table B.id is a foreign key to A. I imported two database schema into the physical layer and for each database, I built the foreign key relationship between table A and B. In the logical layer, I have two logic tables, one to represent A (Dimension) and the other B (Fact) with a logical join. Each logical table has two data sources. For the dimension tables, both id and name columns have two sources. For the fact table, the id has two sources and for the value, I created two separate columns, one called value1 and the other value2 with one from one database's B table's value column and the other from another database's B table's value. They then were made available at presentation layer.
Now in the Anwser, I can build a query with id from dimension and value1 from fact; it displayed fine. Same with a query with id from dimension and value2 from fact, it displayed fine. However, if the query is id, value1 and value2, I got the following error
State: HY000. Code: 10058. [NQODBC] [SQL_STATE: HY000] [nQSError: 10058] A general error has occurred. [nQSError: 15018] Incorrectly defined logical table source (for fact table B) does not contain mapping for [B.value1 [ ] , B.value2 [ ] ]. (HY000)
Is there something I have to do additional to make both values appearing the same time.?
Thanks for your help

Hi, Siddhartha P
I don't think I understand your information. I couldn't find connection pool at the business mapping layer. I only see it in the physical layer. Do you mean to do the mapping at the logical source table? That's only places I see any mappings and I don't see complex join there (only inner join, left outer, right outer and full outer) What mappings should I need to create between table B (fact table) of database 1 and table B (fact table) of database 2. I thought they don't have any relationship other than join through a dimension table which has columns that map to both table A (dimension table) of database 1 and 2. Then the logical fact table has 3 columns, one is id (to join to Dimension table) with two mappings (one to table B of database 1 and one to table B of database 2) and one column value1 which maps only to table B's value of database 1 and another column value2 maps to table B's value of database 2. That seems to be done correctly because I can pick column id and value1 or column id and value2 and have them displayed correctly but not all 3. I thought if it can display the two separately correctly, they should be able to display all 3. no?
I am not getting any inconsistency error.
There must be something I still don't understand. If you don't mind give me a little more direction, that would be great.
