MDX AllMembers doesn't show calculated members - mdx

Question

Say I have as hierarchy [Rank].[Rank] with three members
[Rank].[Rank].&[Boss]
[Rank].[Rank].&[Manager]
[Rank].[Rank].&[Supervisor]
[Rank].[Rank].&[Serf]
Then create a calcuated member in the query
MEMBER [Rank].[Rank].[Middle Managers] AS
[Rank].[Rank].&[Manager] + [Rank].[Rank].&[Supervisor]
if I say
with
member [Rank].[Rank].[Middle Managers] AS
[Rank].[Rank].&[Manager] + [Rank].[Rank].&[Supervisor]
select
{
[Measures].[Hours]
}
on 0
, [Rank].[Rank].[Rank].ALLMEMBERS
on 1
from
some_cube
I don't get the [Rank].[Rank].[Middle Managers] appearing in resultset, but if I use
with
member [Rank].[Rank].[Middle Managers] AS
[Rank].[Rank].&[Manager] + [Rank].[Rank].&[Supervisor]
select
{
[Measures].[Hours On Stack Overflow]
}
on 0
, [Rank].[Rank].[Rank].ALLMEMBERS + [Rank].[Rank].[Middle Managers]
on 1
from
some_cube
I do get it.
But I was under the impression that ALLMEMBERS includes calculated members. Can anyone see what I'm doing wrong please?

Answer 1

Your naming is a bit confusing ([Rank].[Rank].[Rank] vs [Rank].[Rank] usage); you might try (notice the extra [Rank] in the name):
with member [Rank].[Rank].[Rank].[Middle Managers] AS
[Rank].[Rank].&[Manager] + [Rank].[Rank].&[Supervisor]
[edit] is attaching your calc. member into a member that is the level above [Rank] working:
with member [Rank].[Rank].&[Boss].parent.[Middle Managers] AS
[Rank].[Rank].&[Manager] + [Rank].[Rank].&[Supervisor]
