Dimension multiple leaf levels

Question

hi, there is a logical table (business model and mapping) with 6 columns.
the columns are:
region name
region special name
city name
city special name
street name
street special name.
my purpose is to:
when users click "region name" on the dashboard, the drill down is "region name" -> "city name" -> "street name"
when users click "region special name on the dashboard, the drill down is "region special name" -> "city special name" -> "street special name"
"special names" are not in the drill down of "names"
"names" are not in the drill down of "special names".
I build a dimension (business model and mapping) with 4 levels.
grand total level
- region
_region name_
-- city
_city name_
--- street
_street name_
- region special
_region special name_
-- city special
_city special name_
--- street special
_street special name_
(underlined are columns)
but I get an error "not identical leaf levels",
how to achieve my goal?
and is it a must to define ONLY ONE dimension for ONE logical table?

Answer 1

To eliminate this error add detail level (child, lowest level) in the first hierarchy and share it in the second hierarchy. This is must be and if you ommit use for drilldown on the key column on that child/shared/lowest level it will never be displayed, so your two hierarchies will be the same as we defined before. Use primary key (id from table) for the column on this detail level. In the second hierarchy go to Street2/New object/Shared level as child and choose Detail level. Now both have this Detail level.
The dimension is now like:
Total
--Region (column region name is the key use for drilldown)
----City (column city name is the key use for drilldown)
------Street (column street name is the key use for drilldown)
--------Detail (shared level, id is the key not use for drilldown)
--Region2 (column region special name is the key use for drilldown)
----City2 (column city special name is the key use for drilldown)
------Street2 (column street special name is the key use for drilldown)
--------Detail (shared level, id is the key not use for drilldown)
