I think that's because in FoodMart 2005 the Gender hierarchy belongs to the
Customer dimension. So yes, Gender.Gender is short for the level
Customers.Gender.Gender, and Gender is short for the hierarchy
In Mondrian it's a bit different -- the Gender hierarchy belongs to the
Gender dimension, so Gender.Gender properly refers to the hierarchy, not the
However, if we use a more representative example, Customer, which is the
name of a dimension, hierarchy and a level, we get the following behavior on
SSAS 2005, which is consistent with Mondrian with SsasCompatibleNaming=true.
select head([Customer].members, 3) on 0 from [Warehouse and Sales]
gives error "The 'Customer' dimension contains more than one hierarchy"
select head([Customer].[Customer].members, 3) on 0 from [Warehouse and
gives All, A. Catherince Binkley, A. Joyce Jarvis
select head([Customer].[Customer].[Customers].members, 3) on 0 from
[Warehouse and Sales]
gives A. Catherince Binkley, A. Joyce Jarvis, Aaron Carabellos.
I really do want to achieve total compatability with Ssas name-resolution.
If you can find cases where Mondrian differs, please point them out on this
list or log a bug.

The failures are caused by Dimension.Level.Members queries being interpreted
as Dimension.Hierarchy.Members. For example,
select [Gender].[Gender].members on 0 from sales
Row #0: 266,773
Row #0: 131,558
Row #0: 135,215
This is different than SSAS 2005/2008, which excludes the [All Gender].
We can change the tests to match the currently expected syntax for referring
to a level, but I wonder if the real fix here is to modify Mondrian to be
consistent with SSAS behavior.

If I run the test suite with mondrian.olap.SsasCompatibleNaming=true, I get
lots of errors from NativizeSetFunDefTest. This is one of those options for
which the test suite needs to pass regardless of the setting. It's important
that the test suite works with this option set to true, because this will be
the default behavior of mondrian in 4.0.
(You weren't to know that this parameter was important. We're setting up a
hudson instance that tests all of these obscure parameters, and runs on
multiple databases and jdks regularly.)
Can you please fix NativizeSetFunDefTest for this option?
There are also errors in NonEmptyTest, SchemaTest and XmlaBasicTest. I have
not figured out who owns there.
