Skipping a table level

Question

Hi, I have these 3 tables (with right FKs and joins) in my Product Dimension:
CITY, SUPPLIER, PRODUCT.
The right level hierarchy should be, from top to leaves: City -> Supplier -> Product
We'd want to build these dimension hierarchy:
City -> Product, but we get this warning in BI Admin (and error then in Answers)
[39008] Logical dimension table CITY has a source CITY that does not join to any fact source.
It can't navigate through the joins, skipping the intermediate table level?
Are we forced to build the entire hierarchy and skip the level (and the table) setting a preferred Drill-Path? (this solution worked)
Thanks in advance!

Answer 1

To resolve this you have two options.
Be sure that you have in the physical layer correct FK join relationships between these tables as follow:
City-<Supplier-<Product
In the BMM make logical table (dimension table) with logical table source Product. Now, in the logical table source Product general tab properties add physical tables and joins (add first Supplier table and join Product>-Supplier, then add City table and join Supplier>-City). Now, drag-drop columns from all tables that you want to use in dimension levels.
Build dimension object with levels, and put columns on each level.
Option one (all three levels):
City level: key use for drilldown checked
Supplier level: key use for drilldown unchecked
Product level: key use for drilldown checked or unchecked
Now you can drilldown in Answers from City to Product, the middle level is not shown, obiee make join through all three tables.
Option two (City and Product levels only):
City level: key use for drilldown checked
Product level: key use for drilldown checked or unchecked
Now you can drilldown in Answers from City to Product, obiee make join through all three tables, because you have define this additional physical tables and joins in logical table source Product.
