Is it not possible to just have one except clause in a calculated member? (Without using aggregate)
Like this:
MEMBER [Agency].[AgencyName].[Trade] AS (
EXCEPT([Agency].[AgencyName].[All].children, [Agency].[AgencyName].&[Direct Business])
)
In case of sum aggregation go for:
([Agancy].[AgancyName].[All],[Measures].[MyMeasure]) - ([Agancy].[AgancyName].&[Direct Business], [Measures].[MyMeasure])

I am trying to create a calculated measure that finds the difference between two measures by using the following mdx query
WITH MEMBER [Measures].[Available]
AS ([Measures].[Capacity days] ,[Project].[Projects by Name].[All],[Project].[Projects by Code].[All])
- ([Measures].[Worked Days] ,EXCEPT([Project].[Projects by Name].[Project].MEMBERS,
[Project].[Projects by Name].[Project].&[1214]),[Version].[Version].[Combined],[Charge].[Charge].[All])
In case of second measure Worked Days I want to access it with respect to all projects except one ,so am using EXCEPT function which results in the following error
" The function expects a string or numeric expression for the argument. A tuple set expression was used"
Is there any other way to perform this operation?
The query is mixing tuples with sets. Perhaps you can check this gentle introduction of MDX for main concepts and notations.
The second tuple is using a set (the result of EXCEPT) as its second member which is not possible. You could use the aggregate function as following to compute the [Worked Days] over the members of this set instead :
AS ( [Measures].[Capacity days], ... )
- Aggregate(
Except (
[Project].[Projects by Name].[Project].MEMBERS,
[Project].[Projects by Name].[Project].&[1214]
),
( [Measures].[Worked Days], ... )
)
In a previous post I had this script:
WITH
SET [orderedSet] AS
ORDER(
[Operator].members,
[Operator].currentmember.name,
BASC
)
MEMBER [Measures].[newMeasure] AS
RANK(
[Operator].currentmember,
[orderedSet]
)
SELECT
[Measures].[newMeasure] ON COLUMNS,
[orderedSet] ON ROWS
FROM [ourCube]
Plus further reference to the MSDN page
Can the RANK function be used in any clauses other than WITH?
It's first argument is a tuple so I'm not sure how to use it in other clauses such as the SELECT.
It can be used anywhere where a numeric expression can be used.
Please note that in MDX, the axes in the select clause are sets, hence you cannot use Rank or any function that returns a numeric expression in an axis clause, but only functions returning sets (or some data types like tuples which are implicitly converted to sets).
And all members that appear in an expression returning a set have to be defined before you start with this expression. Hence, you cannot define them in the axis clause like you can use expressions to define result columns in SQL selects.
However, to literally answer your question, you can use Rank indirectly in the select clause in MDX e. g. if the outer function is Filter, which returns a set. The following is a slightly inefficient way to show the first three countries according to attribute order:
SELECT {[Measures].[Internet Sales Amount]}
ON COLUMNS,
Filter(
[Customer].[Customer Geography].[Country].Members as C,
Rank(C.Current, [Customer].[Customer Geography].[Country].Members) <= 3
)
ON ROWS
FROM [Adventure Works]
Some people use Rank within Generate to reverse sets, which would be another use of Rank that would be legal in the select clause.
I am new to MDX expressions and I am trying to create one that sums the value of a given measure filtered by dimensions.
In my database I have several different dimensions that have the same name: "Answer". To sum them up, I have created the query below:
WITH MEMBER Measures.Total as SUM ({[Activity].[Activity].&[14], [Activity][Activity].&[22]},
[Measures].[Activity time])
SELECT NON EMPTY [Measures].[Total] on COLUMNS from [My Analytics]
This query works, however I had to use the "&[14]" and "&[22]" statments that correspond to two different "Answer" dimensions.
Since I have more than two dimensions with the same name, is there a way to rewrite the query above in a way that I would select all these dimensions without having to add their unique ID? For example, I would re-write the query as something like this:
WITH MEMBER Measures.Total as SUM ({[Activity].[Activity].&["Answer"]},
[Measures].[Activity time])
SELECT NON EMPTY [Measures].[Total] on COLUMNS from [My Analytics]
Is this possible?
Thanks!
You can use the Filter function as following:
with
set [my-answers] as
Filter( [Activity].[Activity].members,
[Activity].[Activity].currentMember.name = 'Answer'
)
member [Measures].[Total] as Sum( [my-answers] )
...
I am very new to MDX, so probably I'm missing something very simple.
In my cube, I have a dimension [Asset] and a measure [Visits], calculating (in this case) how many visits an asset has been consumed by. An important thing to note is that not every visit is associated with an asset.
What I need to find out is how many visits there are that consumed at least one asset. I wrote the following query:
SELECT
[Asset].[All] ON COLUMNS,
[Measures].[Visits] ON ROWS
FROM
[Analytics]
But this query just returns the total number of visits in the cube. I tried applying the NON EMPTY modifier to both axes, but that doesn't help.
This query should give you what you expect:
WITH MEMBER [Asset].[Asset Name].[All Assets] AS
AGGREGATE( EXCEPT( [Asset].[Asset Name].MEMBERS, { [Asset].[All] } ) )
SELECT
{ [Asset].[Asset Name].[All Assets] } ON COLUMNS,
[Measures].[Visits] ON ROWS
FROM
[Analytics]
You may need to put {[Asset].[Asset Name].[All]} as second argument of Except if the All member was not excluded.
In the query I create a calculated member [Asset].[Asset Name].[all assets] that should represent all your existing assets. I supposed that your existing assets are all the members of the level [Asset].[Asset Name] but the All member.
You can find more information about the Aggregate function here.
This works as well:
SELECT
[Measures].[Visits] ON 0
FROM
[Analytics]
WHERE
DRILLDOWNLEVEL([Asset].[All])
Update: as well as this:
SELECT
[Measures].[Visits] ON 0
FROM
[Analytics]
WHERE
[Asset].[All].CHILDREN
I would to execute a query with a calculated member which returns the AVG (of the measure) of the Coil belonging to a particular LINESPEED.
The query is:
With
Member [Measures].[Avg1] As
AVG(
([LINESPEED].currentmember,
[GRUPPO].[Coil].currentmember)
,
[Measures].[KPI1]
)
SELECT [Measures].[Avg1] on 0,
non empty {[LINESPEED].children} On 1
from[HDGL]
But the AVG function compute exactly the sum of the KPIs of the coil related to a particular LINESPEED!!
Why?
Your formula is using a single tuple, so AVG() is equivalent to SUM() :
AVG( ([LINESPEED].currentmember, [GRUPPO].[Coil].currentmember), ...)
