MDX query on Tabular Model

Hi,
I am very new to SSAS Tabular model and MDX query so I need some help in getting correct query.
I am trying to build a query against a Tabular Model but not sure how to build the query.
I have a Db called 'MyClient' in Analysis Services database. This db has Tables like 'Observations','Scan' etc.
In table I have around 10 to 12 columns like 'Id','ScanId','Title','Date','Impact' etc.. What I am looking for is a MDX query to reterive all the information from Observations table filtered on ScanID? Can someone provide me with a query
If SQL I could have written Select * from Observations where ScanID='22qwe-adfad-12322-adfsdf'.

Hello,
Is "Observation" a fact table or a dimension? In MDX it is not common to query a "detailed list", mostly you query aggregations; but you can query data from a diminsion. Here is an example for the "AdventureWorks" cube with dimension "Customers":
SELECT {} ON 0
{ [Customer].[Customer].[Customer]
* [Customer].[Gender].[Gender]
* [Customer].[Marital Status].[Marital Status] } ON 1
FROM $Customer

SSRS report with tabular model - MDX query to filter parameter data based on Tuple value.

Hello Everyone,
I am working on SSRS report in which a tabular model is being used as a backend.
I want to filter the report parameters which are dependent to other parameters. Like, country, state, and cities drop downs.
All are multi-select parameters. I am using MDX queries to filter the parameters data.
Based on selected one or more countries, the data of states needs to be filtered.
The point is the text which is being displayed in state dropdown for each state name is combination of 3 different members.
So, I created the following Tuple for the same and can see the expected display names in states dropdown.
"("+
[Location].[Code 1].CURRENTMEMBER.UNIQUENAME +","+
[Location].[Code 2].CURRENTMEMBER.UNIQUENAME +","+
[Location].[Descr].CURRENTMEMBER.UNIQUENAME +")"
Now, when I would like filter the cities data based on selected one or more states, I am unable to pass the multiple Tuples (more than one selected Tuples) as parameter for cities dropdown.
The following is my query for City parameter. It is working well when I select only one State from the dropdown.
However, when I select multiple states, it is unable to convert the Tuple into SET in ELSE part of IIF condition specified in following query.
Can anybody help me how to resolve the error that I am getting about STRTOSET function?
Or
Are there any other alternatives to achieve this requirement?
Any help would be much appreciated.
Query:
WITH MEMBER [Measures].[ParameterCaption] AS [City].[City Business].CURRENTMEMBER.MEMBER_CAPTION
MEMBER [Measures].[ParameterValue] AS [City].[City Business].CURRENTMEMBER.UNIQUENAME
MEMBER [Measures].[ParameterLevel] AS [City].[City Business].CURRENTMEMBER.LEVEL.ORDINAL
SELECT {[Measures].[ParameterCaption], [Measures].[ParameterValue], [Measures].[ParameterLevel]} ON COLUMNS ,
[City].[City Business].Children ON ROWS
FROM (
SELECT ( STRTOSET(@State, CONSTRAINED) ) ON COLUMNS FROM [Model])
WHERE ( IIF( STRTOSET(@State).Count= 1,
STRTOTUPLE(@State, CONSTRAINED),
STRTOSET("{
("+
[Location].[Code 1].CURRENTMEMBER.UNIQUENAME +","+
[Location].[Code 2].CURRENTMEMBER.UNIQUENAME +","+
[Location].[Descr].CURRENTMEMBER.UNIQUENAME
+ ")
}",CONSTRAINED )) ) CELL PROPERTIES VALUE

Hi,
I used following dynamic query in expression of dataset of parameter and it works like a charm.
"WITH MEMBER [Measures].[ParameterCaption] AS [City].[City Business].CURRENTMEMBER.MEMBER_CAPTION "&
"MEMBER [Measures].[ParameterValue] AS [City].[City Business].CURRENTMEMBER.UNIQUENAME "&
"MEMBER [Measures].[ParameterLevel] AS [City].[City Business].CURRENTMEMBER.LEVEL.ORDINAL "&
"SELECT {[Measures].[ParameterCaption], [Measures].[ParameterValue], [Measures].[ParameterLevel]} ON COLUMNS , " &
"[City].[City Business].Children ON ROWS " &
" FROM [Model] WHERE ({"& join(Parameters!Location.Value,",") &"}) CELL PROPERTIES VALUE"

SSRS report with tabular model – MDX query CoalesceEmpty function does not return the provided string value

Hello everyone,
I created following calculated member in MDX query. I am using it in one of the report parameter in dataset (single select dropdown list as report parameter).
WITH MEMBER [Measures].[ParameterCaption] AS
CoalesceEmpty([Customer].[National Account Code].CURRENTMEMBER.MEMBER_CAPTION,'None')
I would like to display 'None' text at the top of the dropdown list values. So that when user selects 'None' then this parameter will not considered in MDX query else the selected National Account Code will be considered to filter report data. But,
the above return blank/empty value for [Customer].[National Account Code].& member though I specified 'None' as text in CoalesceEmpty function. Any advice would be appreciated.

SSRS report with tabular model – MDX query how to get the sum and count of measure and dimension respectively.

Hello everyone,
I am using the following MDX query on one of my SSRS report.
SELECT NON EMPTY { [Measures].[Days Outstanding], [Measures].[Amt] } ON COLUMNS,
NON EMPTY { ([Customer].[Customer].[Customer Key].ALLMEMBERS) }
HAVING [Measures].[ Days Outstanding] > 60
DIMENSION PROPERTIES MEMBER_CAPTION, MEMBER_UNIQUE_NAME ON ROWS
FROM ( SELECT ( STRTOSET(@Location, CONSTRAINED)) ON COLUMNS
FROM ( SELECT ( {[Date].[Fiscal Period].&[2014-06]}) ON COLUMNS
FROM [Model]))
Over here, the data is being filtered always for current month and for a location that is being selected by user from a report selection parameter.
I would like to get the count of total no. of customers and sum of the amount measure.
When I am using them in calculated members it gives incorrect values. It considers all records (ignores the sub-select statements) instead of only the records of current month and selected location.
I also tried with EXISTING keyword in calculated members but there is not difference in output. Finally, I manage the same at SSRS level.
Can anybody please advise what are the ways to get the required sum of [Measures].[Amt] and count of [Customer].[Customer].[Customer Key].ALLMEMBERS dimension?
Also, does it make any difference if I manage it as SSRS level and not at MDX query level?
Any help would be much appreciated.

Hi Ankit,
We can use SUM function and COUNT function to sum of [Measures].[Amt] and count of [Customer].[Customer].[Customer Key].ALLMEMBERS dimension. Here is a sample query for you reference.
WITH MEMBER [measures].[SumValue] AS
SUM([Customer].[Customer].ALLMEMBERS,[Measures].[Internet Sales Amount])
MEMBER [measures].[CountValue] AS
COUNT([Customer].[Customer].ALLMEMBERS)
MEMBER [Measures].[DimensionName] AS [Customer].NAME
SELECT {[Measures].[DimensionName],[measures].[SumValue],[measures].[CountValue]} ON 0
FROM [Adventure Works]
Besides, you ask that does it make any difference if I manage it as SSRS level and not at MDX query level. I don't thinks it will make much difference. The total time to generate a reporting server report (RDL) can be divided into 3 elements:Time to retrieve
the data (TimeDataRetrieval);Time to process the report (TimeProcessing);Time to render the report (TimeRendering). If you manage it on MDX query level, then the TimeDataRetrieval might a little longer. If you manage it on report level, then the TimeProcessing
or TimeRendering time might a little longer. You can test it on you report with following query:
SELECT Itempath, TimeStart,TimeDataRetrieval + TimeProcessing + TimeRendering as [total time],
TimeDataRetrieval, TimeProcessing, TimeRendering, ByteCount, [RowCount],Source
FROM ExecutionLog3
WHERE itempath like '%reportname'

SSAS Tabular : MDX query goes OutOfMemory for a larger dataset

Hello all,
I am using SSAS 2012 Tabular to build the cube to support the organizational reporting requirements. Right now the server is Windows 2008 x64 with 16GB of Ram installed. I have the following MDX query. What this query does is get the member caption of the
“OrderGroupNumber” non-key attribute as a measure where order group numbers pertain to a specific day and which occurs in specific seconds of a day. As I want to find in which second I have order group numbers, I cross the time dimension’s members with a specific
day and filter the tuples using the transaction count. The transaction count is a non-zero value if an Order Group Number occurs within a specific second of a selected day.
At present “TransactionsInflight].[OrderGroupNumber].[OrderGroupNumber]” has 170+ million members (Potentially this could grow rapidly) and time dimension has 86400 members.
WITH
MEMBER [Measures].[OrderGroupNumber]
AS IIF([Measures].[Transaction Count] > 0, [TransactionsInflight].[OrderGroupNumber].CURRENTMEMBER.MEMBER_CAPTION,
NULL)
SELECT
NON EMPTY{[TransactionsInflight].[OrderGroupNumber].[OrderGroupNumber].MEMBERS}
ON COLUMNS,
{FILTER(([Date].[Calendar Hierarchy].[Date].&[2012-07-05T00:00:00], [Time].[Time].[Time].MEMBERS),
[Measures].[Transaction Count] > 0) } ON
ROWS
FROM [OrgDataCube]
WHERE [Measures].[OrderGroupNumber]
After I run this query it reaches to a dead-end and freezes the server (Sometimes SSAS server throws OutOfMemory exception but sometimes it does not). Even though I have 16GB of memory it uses all the memory and doing nothing. I have to do a hard-reset against
the server to get the server online. Even I limit the time members using the “:” range operator still the machine freeze. I have run out of solutions to fine-tune the design. Could you guys provide me some guidelines to optimize this query? I am willing to
do a design change if it is necessary.
Thanks and best regards,
Chandima

Hi Greg,
Finally I found the problem why the query goes out of memory in tabular mode. I guess this information will helpful for others and I am posting my findings.
Some of the non-key attribute columns in the tabular model tables (mainly the tables which form dimensions) do not contain pretty names. So for the non-key attribute columns which I need to provide pretty names I renamed the columns to something else.
For an example, in my date dimension there is a non-key attribute named “DateAltKey”. This is the date column which I am using. As this is not pretty to the client tools I renamed this column as “Date” inside the designer (Dimension
design screen). I deployed the cube, processed the cube and no problem.
Now here comes the fun part. For every table, inside the Tables node (Tabular SSAS Database > Tables) you can view the partition details. You have single partition per dimension table if you do not create extra partitions. I opened the partitions screen
and clicked on the “Edit” icon and performed a Syntax Check. Surprisingly it failed. It complains about the renamed column. It complained “Date” cannot be found in source. So I realized that I cannot simply rename the columns like that.
After that I created calculated columns (with a pretty name) for all the columns which complained and all the source columns to the calculated columns were hid from the client tools. I deployed the cube, processed the cube and performed a
syntax check. No errors and everything were perfect.
I ran the query which gave me trouble and guess what... it executed within 5 seconds. My problem is solved. I really do not know who did this improve the performance but the trick worked for me.
Thanks a lot for your support.

Tabular model with Direct Query issue

Hi,
i am creating a tabular model - Direct Query option. I am using a kind of below query to import data,
Declare @TEST as Table (TestID int, TestName varchar(20))
Insert into @TEST
Select 1, 'TEst1' Union
Select 2, 'TEst2'
Select * from @TEST
But the Import fails with an error similar to below,
OLE DB or ODBC error. An error occurred while processing the partition 'Query_``````````' in table 'Query_````````'. The current operation was cancelled because another operation in the transaction failed.
Any idea, why it is failing ? or is it like we shouldn't use declare statement in the Query area ?
Please reply ...Thanks in advance !
--------------------------- Radhai Krish | Golden Age is no more far | --------------------------

I'm pretty sure that the query would have to be a single statement so the declare statement would be causing issues.
So just doing this as a single union query should work:
Select 1 as TestID, 'TEst1' as TestName Union
Select 2, 'TEst2'

Reading the DAX query plan of a trace against a query on a Tabular model

Hi,
I'm monitoring a Tabular model queried by an Excel workbook. Inside SQL Profiler I've choosen as events the VertiPaq SE Query End, the Query End and the DAX Query Plan. But this last event isn't more readable.
How can I read the info collected in the DAX Query Plan in a simple manner?
Thanks

It is fairly complex to read the DAX Query Plan. I don't think there are currently tools that make it easier to read. (Watch the DAX Studio project on codeplex as they may include tools for this in the future.) I would recommend you review the Tabular
Performance Guide which has a good explanation of the DAX Query Plan:

SSRS Parameters using SSAS Tabular model get cleared

I have an SSRS report that uses data from a SSAS Tabular model. In the query designer, from the calendar dimension I choose a "Date Inclusive" filter and make it a parameter. I also choose to add another filter using and Organisation Unit
dimension and also make this a parameter. The report is written and deployed to a SharePoint 2013 library.
Most of the time, the report runs as expected with the parameters cascading off each other as expected. However, occasionally, parameters get cleared (either after changing a single value such as the Org Unit selection or sometime whilst the report
is being rendered). Sometimes you cannot select a value from the available values - you need to navigate somewhere else and then start over.
I changed the data source for the parameters to use SQL queries that return the same values as the MDX queries and the probably seems to have gone (time will tell)
This report has a child (detail) report that has one extract parameter. This parameter happens to have over 1,000 values. With the change of the parent report, you are now able to get to the child report. However, the child report seems
to exhibit the same problem with the parameters being cleared - and with a much higher frequency.
So, that leaves me wondering whether
anyone else has experienced this ?
is this an issue with SSRS 2012 and SSAS Tabular models (I have not seen this behaviour before and I have been using SSRS (since version 1) and SSAS Multi-dimensional (from when it was called "OLAP Services") ?

We applied SQL Server 2012 Service Pack 2 to the SharePoint farm (the SP Admin needed to re-create the service applications) and the problem is fixed

Ordering MDX query wih Named set gives error, "The CURRENT function cannot be invoked in this context ".

Hi,
I have following Query
WITH SET [Union name set test] AS {[Union].[Union Name].&[2],[Union].[Union Name].&[3],
[Union].[Union Name].&[4],[Union].[Union Name].&[5],[Union].[Union Name].&[6]}
SELECT {[Measures].[Emp Count]} ON 0,
{ORDER({[Union].[Union City].[Union City]*[Union name set test]},
[Union name set test].CURRENTMEMBER.MEMBERVALUE, BASC)} ON 1 FROM [Federations];
when i run this query from code as well as SSMS i get following error...
The CURRENT function cannot be invoked in this context because the 'Union name set test' set is not in the scope.
Please help me for this ....

Hi Mihirhp,
Base on my research, there are some similar issues and the resault turn out that the Tabular model engine can’t associate .currentmember with a set. The workaround is to use .current in the MDX query. Please try the query below.
WITH SET [Union name set test] AS {[Union].[Union Name].&[2],[Union].[Union Name].&[3],
[Union].[Union Name].&[4],[Union].[Union Name].&[5],[Union].[Union Name].&[6]}
SELECT {[Measures].[Emp Count]} ON 0,
{ORDER({[Union].[Union City].[Union City]*[Union name set test]},
[Union name set test].CURRENT.MEMBERVALUE, BASC)} ON 1 FROM [Federations];
Hope this helps.

Tabular model performance

HI,
I have built a small database of size 31 MB on tabular mode. DB querymode is set to InMemory. With simple setup, a normal evaluate dax query is taking 1 sec to retrieve list of sales person which is a dimension table and does not include any calculation.
The other semi complex query are taking 15- 20 secs. The tabular instance setting are set to default as the db size is less and server as total of 7 GB RAM.
Is there any setting that needs to be validated to improve the performance.Because if the model is inmemory then the output should come out in microseconds.
Manohar K - SQL Server DBA Consultant

Hi Manohar,
According to your description, you are experienciing the performance issue when retrieval data from the small SQL Server Analysis Services Tabular model, right?
In tabular model, as you increase the data load, add more users, or run complex queries, you need to have a strategy for maintaining and tuning performance. Here are some links which describe strategies and specific techniques for getting the best performance
from your tabular models, including processing and partitioning strategies, DAX query tuning, and server tuning for specific workloads. Please refer to the links below.

http://sqlblog.com/blogs/marco_russo/archive/2013/08/05/performance-tuning-of-tabular-models-in-analysis-services-2012-ssas.aspx
Besides, I'd suggest you enable SQL Server profiler to monitor the query, and check which part in the query took a very long time to run. Here is a useful link for your reference.

Report using Tabular Model and Measures based on Distinct Counts

Hello,
I am creating a report that should present something like this:
YEAR-1 | MONTH-1 | MONTH-2 | MONTH-3... | YEAR | MONTH-1 | MONTH-2 | MONTH-3...
My problem is that when designing the dataset to support this layout I drag the Year, Month and Distinct count Measure, but on the report when I want the value for the YEAR level I don't have it and I cannot sum the months value...
What is the best aproach to solve this? Do I really have to go to advanced mode and customize my MDX or DAX? Can't basic users do something like this that seems so trivial and needed?
Thank you
Luis Simões

Hi Luis,
According to your description, you create a Reporting Services report using Analysis Service Tabular Model as the datasource, now what you want is sum the months value on year level, right?
In your scenario, you can add the Month field to column group, add a parent group using Year Field and then add a Total on Month group. In this case, Reporting Services will sum the months value on Year level. I have tested it on my local environment, the
screenshot below is for you reference.
Reference:Lesson 6: Adding Grouping and Totals (Reporting Services)
If this is not what you want, please describe your dataset structure, so that we can make further analysis.

Creating Tabular Models using AMO

Hi,
I am trying to setup Tabular Models on SSAS using AMO referring to the materials available at Technet and the Codeplex AMO Tabular Tutorial. I have a few questions/issues
currently and was hoping I could get some help from here. The tool I am working with currently supports Multidimensional mode via AMO and I am trying to extend most of its features from the Multidimensional model. So, some of the questions might not exactly
fit into the Tabular model and if so, please do point them out.
RELATIONSHIPS: While creating relationships among tables,
would it suffice to create the relationship in the Data Source View Schema (as the tool currently does for the Multidimensional mode) or should we explicitly create relationships under the dimensions that we create to represent the table in Tabular mode? The
latter is the approach mentioned in the tutorial and I wanted to know if there is any difference between the relationships created using the 2 methods.
MEASURES: I am trying to create measures using Native
OLAP Measure objects in the Tabular model. I understand the shortcomings of this type of measures but I would still need to create them for basic aggregation functions like SUMMATION, COUNTS etc… I tried creating the measures using the same Measure Group that
was created to represent the table and used a ColumnBinding to the Measure’s source-column for the measure object’s source property but I get the following error:
Binding for VertiPaq measure MEASURE_NAME in measure group MEASURE_GROUP_NAME is invalid because it does not match any property binding of the fact dimension
TABLE_NAME
Am I missing anything here? Is there a better way of creating OLAP measures in TABULAR model without using the default Table dimensions that we create?
HIERARCHIES: I tried creating new Dimensions to hold
hierarchies for a table but when creating them, I get the error about MISSING ROWNUMBER attribute. Is this attribute mandatory for every dimension that is created?
To avoid this problem, I used the same dimension that was created to represent the table and tried adding inter-table attribute relationships to it but I get the following exception
message which I cannot figure out.
VertiPaq property ‘’ cannot have a name binding.
In general, can we create separate measure groups and dimensions, apart from the ones we use to represent the table, to store the custom measures and hierarchies? Is this a recommended
approach? This way, I am trying to keep things in parallel with the Multidimensional model that our tool currently supports but when I create such individual dimensions and measure groups, I get an error on the mismatch between the number of measure groups
and dimensions in the table.
Please bear with the long list of questions. I could not find any help online for these and so am posting them all here.
Thank you.

No - relationships in the DSV have no impact on the end model. You need to explicitly create relationships between your dimensions and measure groups for them to be picked up as relationships in your tabular model.

Measure objects in the Tabular model. I understand the shortcomings of this type of measures but I would still need to create them for basic aggregation functions like SUMMATION, COUNTS etc… I tried creating the measures using the same Measure Group that was

Am I missing anything here? Is there a better way of creating OLAP measures in TABULAR model without using the default Table dimensions that we create?
There is no concept of native measures in a Tabular model. You need to create all your measures as "Calculated Measures" in AMO, but using the appropriate DAX expressions instead of MDX.
HIERARCHIES: I tried creating new Dimensions to hold hierarchies
for a table but when creating them, I get the error about MISSING ROWNUMBER attribute. Is this attribute mandatory for every dimension that is created?
To avoid this problem, I used the same dimension that was created to represent the table and tried adding inter-table attribute relationships to it but I get the following exception message
which I cannot figure out.

Yes, I believe every table needs the hidden RowNumber attribute. The
TableAddEmptyTable function in the tabular AMO sample on codeplex shows you how to create this.
In general, can we create separate measure groups and dimensions, apart from the ones we use to represent the table, to store the custom measures and hierarchies? Is this a recommended
approach? This way, I am trying to keep things in parallel with the Multidimensional model that our tool currently supports but when I create such individual dimensions and measure groups, I get an error on the mismatch between the number of measure groups
and dimensions in the table.
No you can't create any extra structures. Tabular projects only supports a subset of AMO. You need to follow the example on codeplex very closely and read all the code comments if you are making changes because it's very easy to break things.
My suggestion is to create an abstraction layer either using the TabularAMO library from codeplex as it is or creating your own library if you only need a subset of the functionality. This will mean that your core code is not too tightly bound to AMO. The
reason for this is that I would hope that MS will replace AMO with something better for Tabular models in a coming release and having a clear abstraction layer should make it easier to update to a new API.

Tabular Modeling. What is the best practice for importing data into VS to limit the records in the designer?

Should I wrap the queries in a procedure with a @StartDate and @EndDate and create a test partition to pass a small date range?
Or can i use the Table properties screen to put the command there and will it run and not be affected or affect the partitions?This would be nice if this SQL statement on this screen was independent of the partitions and I could just leave it with the the
command text = EXEC TransactionDetail '2014-01-01', '2014-05-31' Especially since if you have many tables that load based on a date range. i would not want to jump in and change that query on all of them.
Is there a a way to have a parameter in the project so all tables would get the same @startDate and @EndDate so I could change it in one place?
And I am not stuck to these questions\options, If there is a better way to mass change the queries to run a subset of data for the designer I'd like to hear it.
Thank You,
Phil

Hi Phil,
According to your description, you are looking for the best way to control the rows that are loaded into a table, right?
When importing data to a table of tabular model, we can apply filters to control the rows that are loaded into a table. After you have imported the data, you cannot delete individual rows. However, you can apply custom filters to control the way that
rows are displayed. Rows that do not meet the filtering criteria are hidden. For the detail information about it, please refer to the link below.Filter Data in a Table (SSAS Tabular)
If I have anything misunderstand, please point it out.
