[39008] Logical dimension table ... has a source ... that does not join to

Question

Oracle BI 11g
Hi,
I have this set of tables:
1) Table "Sales" with fields: ID, Billdate, ProductID, Amount
2) Table "Products" with fields: ID, ProductName, BrandID, TypeID
3) Table "Brands" with fields: ID, Name
4) Table "ProductTypes": ID, Name
In Physical layer I add these tables and create Physical Diagram with constraints like this:
[Brands] -------------------->[Products]
[ProductTypes] ---------->[Products]
[Products] -----------------> [Sales]
In Logical Layer I create logical table T1 Products with sources:
- LTS1 Brands,
- LTS2 ProductTypes,
- LTS3 Products
and fields:
- ProductID
- ProductName
- Brand
- ProductType
After that I create Dimention With Level-Based Hierarchy (H1 Products):
Total Products
- Brands
-- ProductTypes
--- Detail Products
When I try "Check Global Consistency" I get warning: "[39008] Logical dimension table T1 Products has a source LTS1 Brends that does not join to any fact source."
And after that when I try to make Analysis in Oracle BI, for example:
H1 Products | Amount
and then drill down item "Total Products" I receive error:
"State: HY000. Code: 10058. [NQODBC] [SQL_STATE: HY000] [nQSError: 10058] A general error has occurred. [nQSError: 43113] Message returned from OBIS. [nQSError: 43119] Query Failed: [nQSError: 14025] No fact table exists at the requested level of detail: [,Brand,,,,,,,,,]. (HY000)"
What's wrong? Where do I mistake? And why I don't get any messages about Logical Table Source LTS2 Product Type?

Answer 1

Hi,
you can create a single LTS for the product with the join for all 3 tables. Do you have a particular reason for the modelling that you have used?
