Pre order, Post order, Level order (BFS) traversing with MDX

A tree or hierarchy of my sample cube is being shown below:


BFS or Level Order Traversing:

with
member [Measures].[x]
as [Dim Category].[Parent].currentmember.level.ordinal

select
order(([Dim Category].[Parent].members),[Measures].[x],BASC)
on 1 ,
[Measures].[x] on 0
from SalesCube
And, here goes the output:


Pre-Order traversing:
By default, traversing in MDX is always in pre-order.
select [Dim Category].[Parent].members
on 1 ,
[Measures].[Sales] on 0
from SalesCube


Post-Order Traversing:
Using “Hierarchize” function, with parameter “POST”
select
hierarchize([Dim Category].[Parent].members,post)
on 1 ,
[Measures].[Sales] on 0
from SalesCube
