Cross join same hierarchy columns - sql

Question

I have a SQL data cube with following hierarchy
I want to cross join Warehouse division and Code warehouse Desc. I wrote a MDX as follows
SELECT NON EMPTY
{ [Measures].[Total Value]}
DIMENSION PROPERTIES CHILDREN_CARDINALITY,
PARENT_UNIQUE_NAME ON COLUMNS,
NON EMPTY
{
[Combined].[Drill Down Path 4].[Warehouse Division].MEMBERS* [Combined].[Drill Down Path 4].[Code Warehouse Desc].MEMBERS
}
DIMENSION PROPERTIES MEMBER_CAPTION ON ROWS FROM [InventoryAge]
WHERE ( [Calendar].[Report Days].[All Members].&[All].&[WantInReport].& [2].&[20141031] )
It gives me an error as follows
Query (13, 8) The Drill Down Path 4 hierarchy is used more than once in the Crossjoin function.
Can any body suggests a better way to do this
Please find the calender hierarchy

Answer 1

You don't need to crossjoin hierarchy (this is impossible) to do what you need. Just query the lowest level of it, you will get all parents also
SELECT NON EMPTY
{ [Measures].[Total Value]}
DIMENSION PROPERTIES CHILDREN_CARDINALITY,
PARENT_UNIQUE_NAME ON COLUMNS,
NON EMPTY
{
[Combined].[Drill Down Path 4].[Code Warehouse Desc].allMEMBERS
}
DIMENSION PROPERTIES MEMBER_CAPTION ON ROWS FROM [InventoryAge]
WHERE ( [Calendar].[Report Days].[All Members].&[All].&[WantInReport].& [2].&[20141031] )
PS. You might not be able to see them in SSMS query result viewer, but they will appear if you use query in cube browser or as dataset in SSRS/other tool

Answer 2

You can pass last date in your set by using Tail(Existing [Calendar].[Report Days].[All Members].&[All].&[WantInReport].members, 1).item(0)
Or you can use Format(Now()), which gives you string representation of current system date. However, it depends on locale, so you probably need to remove dots/slashes. See here
