Welcome to everyone.
I would be very thanks if anyone help me. I am not too expert writing mdx query.
I am working in a software that build a mdx query to get info from a OLAP structure.
I get the result when I filter by a dimension, but I need to filter by many.
my structure is
CodGer : A, B, C, D
CodModel : A01, A02, A03, B01, B02,B03 ...
With this query I get all element from A1, and that is right.
Select {[Measures].allmembers} on columns
, non empty {
[ModelosGers].[CodGer].[A] *
{[ModelosGers].[CodModel].[A01] } } on rows
From [Tasas]
where {[Periodos].[Periodos].[Periodos].[260]}
But, in fact, I also need, for example, get all element from A and B01.
In sql could be like
Select * from Tasas where [Periodos].[Periodos].[Periodos]=260 and( [ModelosGers].[CodGer] like 'A' or [ModelosGers].[CodModel]='B01')
I have been research filters and where clause MDX but I do obtain the right query.
Can anyone help me?
Thanks
Finally I resolved my selft traying differents posts like
And-Or in MDX queries
Select {[Measures].allmembers} on columns
, non empty {
{([ModelosGers].[CodGer].[A] ,[ModelosGers].[CodModelo].defaultmember ) ,
([ModelosGers].[CodGer].defaultmember ,[ModelosGers].[CodModelo].[B01] ) }
} on rows
From [Tasas] where {[Periodos].[Periodos].[Periodos].[260]}

I'm completely new to SSAS cubes and terminologies (members, hierarchies, e.t.c) and MDX queries but i have started my journey to learn this stuff, so apologies if my question is very clear.
SELECT NON EMPTY { } ON COLUMNS, {
[Suggestions].[Parent_id].[Parent_id] *--.ALLMEMBERS *
[Suggestions].[id].[id] * --.ALLMEMBERS *
[Suggestions].[Sugg - #].[Sugg - #] *-- .ALLMEMBERS *
[Suggestions].[Sugg - Assigned].[Sugg - Assigned] * --.ALLMEMBERS *
[Suggestions].[Sugg - Assigned to].[Sugg - Assigned to]* --.ALLMEMBERS *
[Suggestions].[Sugg - Status].[Sugg - Status] *--.ALLMEMBERS
--[Parent_Details].[Unit_Name].[Unit_Name] --.ALLMEMBERS
}
DIMENSION PROPERTIES MEMBER_CAPTION,
MEMBER_UNIQUE_NAME ON ROWS
FROM ( SELECT ( { [Suggestions].[Sugg - Assigned to].&[UNIT] } ) ON COLUMNS
FROM ( SELECT ( STRTOSET('SG123', CONSTRAINED) ) ON COLUMNS
FROM ( SELECT ( { [Suggestions].[Sugg - Status].&[Pending Inputt] } ) ON COLUMNS
FROM [BOI_Tracker-Stats])))
CELL PROPERTIES VALUE
I have the above MDX query that executing. I generated the query from the MDX query designer tool in SSMS and have only simple modifications by hand.
In the query, if i comment out the line [Parent_Details].[Unit_Name].[Unit_Name] --.ALLMEMBERS, i get the correct number of rows.
Main Question.
If i un-comment it so that i return the Unit_Name column, my rows are duplicated. The original 100 correct rows now because thousands of rows with duplicate values all over. Any body know what i should look out for that is causing this. Looks a wrong join is being applied.
Other things i would like to understand.
1. The query designer generated the query in the format
[Suggestions].[Parent_id].[Parent_id].ALLMEMBERS * . If i comment out .ALLMEMBERS * such that the query is just [Suggestions].[Parent_id].[Parent_id] with out .ALLMEMBERS * the results are the same. So what is the use of .ALLMEMBERS *
2. I also notice that the column i want to select is repeated twice like
Suggestions].[Parent_id].[Parent_id], why is this so?, why can't it just be generated as Suggestions].[Parent_id]
If you select from different dimensions like that you basically multiply the results. If you think about it that's the correct behavior. In your case you have [Suggestions] and [Parent_Details] . These are different dimensions. In your query you want results having both so it does:
For each member of [Suggestion] get all members of [Parent Details] and add them to the result. So the result set becomes:
[Suggestion-1][Parent_Details-1][Measures...]
[Suggestion-1][Parent_Details-2][Measures...]
[Suggestion-2][Parent_Details-1][Measures...]
[Suggestion-2][Parent_Details-2][Measures...]
[Suggestion-3][Parent_Details-1][Measures...]
etc.
( having different levels from the [Suggestions] dimension doesn't multiply the measures )
This is a correct behavior when you think about it because if you add these two dimensions you probably want to know something like "What are the measures for that suggestion and for these parent details?" And that exact row will be correct in the result set. It all depends on what result do you want to get (What do you ask for).
The multiplication of the names depends on your cube design. First row is a level and second a member. If you create a hierarchy for example it will not look like that.
I would like to make a BAPI call from Java to the BAPI "BAPI_MDDATASET_CREATE_OBJECT".
Therefore I want to use the following MDX Query:
SELECT
[0DISTR_CHAN].Members ON COLUMNS,
[0MATERIAL].Members ON ROWS
FROM [$/PKG/AB_C01]
Because the Parameter "COMMAND_TEXT" is to short I made 4 entries like this:
Now I run the BAPI and get a DATASETID in return. I use this id with the next BAPI "BAPI_MDDATASET_CHECK_SYNTAX"
But now I get an exception:
English Version:
Why is this so?
This MDX query seems to be OK, because in transcation "MDXTEST" this query is working.
Any suggestions?
I had the same problem only with c# and sap connector.
I solved it. Need to use all commands in one context:
RfcSessionManager.BeginContext(destination);
Create_Object();
CheckSyntax();
etc.
RfcSessionManager.EndContext(this.destination);
The following will return a large table that is n * m where n are the number of columns and m is the number of rows:
SELECT
[0DISTR_CHAN].Members ON COLUMNS,
[0MATERIAL].Members ON ROWS
FROM [$/PKG/AB_C01]
n = number of members in this dimension [0DISTR_CHAN] + 1
m = number of members in this dimension [0MATERIAL]
This is not an answer but maybe will help to discover if the mdx is the problem. If you simplify the above to just a single member on rows, and a single member on columns do you still get an error?
SELECT
{[0DISTR_CHAN].[0DISTR_CHAN].[someMemberY]} ON COLUMNS,
{[0MATERIAL].[0MATERIAL].[someMemberX]} ON ROWS
FROM [$/PKG/AB_C01];
Right now I'm dealing with a program that can generate and return SQL or MDX queries (depending on the source database of the queries). I'm working on adding a feature that counts all the rows returned by a given query.
Now, I have some small background with SQL, so I was able to parse table names and generate a rowcount. However, MDX is a completely new beast for me.
In SQL, I'm creating:
SELECT
COUNT(SUM)
AS ROWS
FROM
(
COUNT(*) AS COUNT FROM TABLE1
UNION ALL
COUNT(*) AS COUNT FROM TABLE2
UNION ALL
COUNT(*) AS COUNT FROM TABLE3
ETC...
)
Now, what I'm wondering is, how would I do something similar with MDX? I've done some reading on MDX, and from what I gathered the basic notation is
[Dimension].[Hierarchy].[Level]
Now with SQL, I parsed the table names out of a larger generated query and simply inserted them into a new programmatically generated query. What would I have to grab from a larger MDX query to generate my own rowcounting query and sending it off to run? A simpler example of the MDX I'm dealing with would be:
WITH
MEMBER [BUSINESS1].[XQE_RS_CM1] AS '([BUSINESS1].[COMPANY_H].[all])', SOLVE_ORDER = 8
MEMBER [BUSINESS2].[XQE_RS_CM0] AS '([BUSINESS2].[all])', SOLVE_ORDER = 4
SELECT
NON EMPTY {[BUSINESS2].[ALL_TIME_H].[CALENDAR_YEAR_L].MEMBERS AS [XQE_SA1] , HEAD({[BUSINESS2].[XQE_RS_CM0]}, COUNT(HEAD([XQE_SA1]), INCLUDEEMPTY))} DIMENSION PROPERTIES PARENT_LEVEL, PARENT_UNIQUE_NAME ON AXIS(0),
NON EMPTY {[BUSINESS1].[COMPANY_H].[COMPANY_CD__L].MEMBERS AS [XQE_SA0] , HEAD({[BUSINESS1].[XQE_RS_CM1]}, COUNT(HEAD([XQE_SA0]), INCLUDEEMPTY))} DIMENSION PROPERTIES PARENT_LEVEL, PARENT_UNIQUE_NAME ON AXIS(1),
NON EMPTY {[Measures].[Measures].[BUSINESS3]} DIMENSION PROPERTIES PARENT_LEVEL, PARENT_UNIQUE_NAME ON AXIS(2)
FROM
[SOURCE] CELL PROPERTIES CELL_ORDINAL, FORMAT_STRING, VALUE
Any insight would be awesome, thanks.
At first glance your script looks reasonable then after unravelling it becomes a bit(!) more complex.
The main difference between this and other scripts is its use of axis(2). In a sub-select extra dimensions are often used but this is a little odd as most clients can't handle 3 dimensional cellsets - so I'm intrigued by what is consuming this info?
Also the member [BUSINESS1].[XQE_RS_CM1] is a single member as is [BUSINESS2].[XQE_RS_CM0] so what is the point of the sections HEAD... ?
WITH
MEMBER [BUSINESS1].[XQE_RS_CM1] AS
([BUSINESS1].[COMPANY_H].[all]), SOLVE_ORDER = 8
MEMBER [BUSINESS2].[XQE_RS_CM0] AS
([BUSINESS2].[all]), SOLVE_ORDER = 4
SELECT
NON EMPTY
{[BUSINESS2].[ALL_TIME_H].[CALENDAR_YEAR_L].MEMBERS AS [XQE_SA1]
,HEAD(
{[BUSINESS2].[XQE_RS_CM0]},
COUNT(
HEAD([XQE_SA1])
,INCLUDEEMPTY
)
)}
ON AXIS(0),
NON EMPTY
{[BUSINESS1].[COMPANY_H].[COMPANY_CD__L].MEMBERS AS [XQE_SA0]
,HEAD(
{[BUSINESS1].[XQE_RS_CM1]},
COUNT(
HEAD([XQE_SA0])
,INCLUDEEMPTY
)
)}
ON AXIS(1),
NON EMPTY
{
[Measures].[Measures].[BUSINESS3]
}
ON AXIS(2)
FROM
[SOURCE]
Does the following return the same data as the original script?
SELECT
NON EMPTY
{
[BUSINESS2].[ALL_TIME_H].[CALENDAR_YEAR_L].MEMBERS
,[BUSINESS2].[all]
}
ON 0,
NON EMPTY
{
[BUSINESS1].[COMPANY_H].[COMPANY_CD__L].MEMBERS
,[BUSINESS1].[COMPANY_H].[all]
}
ON 1
FROM [SOURCE]
WHERE [Measures].[Measures].[BUSINESS3];
All you need to calculate then is the count of members returned in the following set on the rows:
{
[BUSINESS1].[COMPANY_H].[COMPANY_CD__L].MEMBERS
,[BUSINESS1].[COMPANY_H].[all]
}
I have an MDX query as follows:
WITH
MEMBER [MatCode] AS [Product].[Material]
SELECT
([MatCode]) on 0,
([Activity].[ActivityCode].[T-50051151]) ON 1
FROM
[Cube]
This returns a value such as:
MatCode
T-50051151 Null
Which tells me it is not joining the activity code to the description when I know they match up
How can I correct my MDX query to join activity code to material?
thanks
Why not try something like the following to look for areas of the cube with data? You'll can use the WHERE clause to slice by a specific measure in your cube.
SELECT
{[Activity].[ActivityCode].[T-50051151]} ON 0,
//NON EMPTY //<<include to hide nulls
{[Product].[Material].members} on 1
FROM
[Cube]
WHERE
([Measures].[someMeasure])
Your query returns the _ default _ value / cell for the tuple :
( [Activity].[ActivityCode].[T-50051151], [Product].[Material].defaultMember )
as well as the .defaultMember for every other dimension not mentionned in your query. There is nothing wrong with it.
I've just started to learn MDX and i want to do a query like that:
filter data by the cost ( i've already made that query but without the sum) like that:
SELECT [Measures].[SumOfSelled] ON 0,
FILTER ([From].[From].[City].members, [Measures].[SumOfSelled]>7000) ON 1
FROM [BI-Avia]
It's working
and it is OK
BUT!!!
I need also to show the sum of filtered elements under this filtered result by cities
I know how to find it separately:
with member [Measures].FilteredSum as sum(filter([From].From].City].members,Measures].SunOfSelled]>7000),Measures].[SumOfSelled])
select{SumOfSelled} on 0
from [BI-AVIA]
But i have to show this together!! The SUM under Filtered! two in one! I need youe help! I think it's very clear for you!!!
Just define the calculated member on the [From].[From] hierarchy and then combine both queries, using a union of sets (abbreviated with + in MDX):
with member [From].[From].FilteredSum as
sum(filter([From].[From].City].members, Measures].SumOfSelled]>7000))
SELECT [Measures].[SumOfSelled]
ON 0,
FILTER ([From].[From].[City].members, [Measures].[SumOfSelled]>7000)
+
{ [From].[From].FilteredSum }
ON 1
FROM [BI-Avia]
You could possibly define the filter as a set in the WITH clause, which would avoid that Analysis Services evaluates it twice.
