How can i use CalculatedMember (dimension, not measure) in Pentaho xml schema? - schema

Question

I have this MDX query:
WITH
MEMBER [CLIENT].[WITHOUT CLIENT X] AS
'[CLIENT].[All CLIENTs] - [CLIENT].[CLIENT X]'
SELECT
[Measures].[Sales] ON COLUMNS
,{[STORE].[All STOREs].Children} ON ROWS
FROM [Sales]
WHERE
CrossJoin
(
{[YEAR].[2015]}
,{[CLIENT].[WITHOUT CLIENT X]}
);
This query return corect result (All stores sales without [CLIENT].[CLIENT X]).
Now, I want to use this calculated member ([CLIENT].[WITHOUT CLIENT X]) in Saiku, OpenI, BTable or Pivot4J as a normal dimension or something like this.
For this i added in schema.xml:
<CalculatedMember name="WITHOUT CLIENT X"
formula="([CLIENT].[All CLIENTs] - [CLIENT].[CLIENT X])" hierarchy="CLIENT" parent="CLIENT" visible="true"></CalculatedMember>
If i run:
Select [Measures].[Sales] on COLUMNS,
{[STORE].[All STOREs].Children} ON ROWS
from [Sales]
WHERE CrossJoin({[YEAR].[2015]}, {[CLIENT].[WITHOUT CLIENT X]})
the result returned is corect, but i can't see this dimension [CLIENT].[WITHOUT CLIENT X].
In Saiku, OpenI or Pivot4J i can't find this dimension.
BTable get this dimension as MEASURES because of CDA (/api/olap/getCubeStructure) and result is this:
{
"type": "measure",
"name": "WITHOUT CLIENT X",
"caption": "WITHOUT CLIENT X]",
"qualifiedName": "[CLIENT].[CLIENT X]",
"memberType": "FORMULA"
}
but is useless because I can't use in filter.
Do you have same answers?
Posible questions:
Why u use member and not named set?
Because dimension CLIENT it's huge (more than 50000) query with member run in 1 sec and with set in more than 5 minutes
why don't use EXCEPT?
Same as 1.
why not use just mdx query?
Because final report is for non-tehnic and they want to change this filter.
UPDATE INFO
I renamed [CLIENT].[WITHOUT_this_CLIENT] with [CLIENT].[WITHOUT CLIENT X] and [CLIENT].[My Special Client] with *[CLIENT].[CLIENT X]*to avoid some confusion.
I want to filter a level in this way: add all members (CLIENT) except one (CLIENT X).
The result returned is corect when i use mdx query, because GUI OLAP clients cant read my xml schema.
I don't know where is my error.
Thank you,

SOLVED
For what I want (filtering one element from a big list) the answer is this:
I created another dimension, which is used just for filter.
<Dimension type="StandardDimension" visible="true" highCardinality="false" name="CLIENT X">
<Hierarchy visible="true" hasAll="true">
<Table name="SALES" schema="SALES" />
<Level name="CLIENT X" visible="true" column="CLIENT" type="String" uniqueMembers="false" levelType="Regular" hideMemberIf="Never">
<KeyExpression>
<SQL dialect="oracle">
<![CDATA[CASE WHEN CLIENT = 'CLIENT X' THEN 'CLIENT X' ELSE 'WITHOUT CLIENT X' END]]>
</SQL>
</KeyExpression>
</Level>
</Hierarchy>
</Dimension>

You're not defining your member correctly. ie. The parent member must be the fully qualified name of the parent of the newly created member, not the level's name. Read this carefully and you'll figure it out.
