Tabular Model Partition

Hi everyone
Please help me,
I am new to the tabular model
My table data size big having millions of records , i need to apply the Partition on my tables month wise or Year wise.
I have search many blogs but i could not able to find the right solution,
please help anyone i need step by step process.
please anyone share the documentation or link.
its very helpful.
Regards
Sreeni

Hi Sreeni,
Partitions divide a table into logical parts, and each partition can then be processed (Refreshed) independent of other partitions. In this case, you should group by your partitions at month level, so we can directy process the "Jan-2014" partition to load
data for business requirement.
Besides, we can process the parition via SSIS package. Here are some articles for your reference, please see:

Error while importing data in SSAS Tabular Model

I am new to the concept Tabular Model in SSAS 2014.
I am trying to create one tabular model based on Adventureworks DW 2014.
I am getting below error while importing tables to create model.
"OLE DB or ODBC error: Login failed for user 'ASIAPAC\CSCINDAE732028$'.; 28000.
A connection could not be made to the data source with the DataSourceID of '98c2d415-1e84-469c-a170-2bcacd779c1a', Name of 'Adventure Works DB from SQL'.
An error occurred while processing the partition 'Customer_65240c88-55e7-416c-a7ac-732dece8be8e' in table 'Customer_65240c88-55e7-416c-a7ac-732dece8be8e'.
The current operation was cancelled because another operation in the transaction failed."
But while creating the Datasource, it has created successfully (below img)
But while importing the facing the below error.
Note:
I have multiple instances in my system with unique names.
Is this causing any ambiguity issues in selecting right instances?

Hi Naveen，
Based on your screenshots, you fail to open a connection to the data source. Right?
In this scenario, the first screenshot you post is for creating a connection to server with the current windows authentication, not for connecting a data source. So the "Test Connection succeed" means your current windows user can connect
to server, not connect to the database your selected in the dropdown list. Then you click next, you can choose account to access the data source. Based on the information, your service account "'ASIAPAC\CSCINDAE732028$" doesn't have permission to
access the database you selected. Please grant the permission for the service account in SSMS.
If you have any question, please feel free to ask.

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.

VS2010 SSAS Tabular Model Memory Limitation

Hi,
My laptop recently crashed and am currently using a loan one that has Windows 7 x32, Visual Studio 2010 SP 1 AND SQL Server 2012 SP 1 (CU 4) installed. It only has 4GB of RAM, and when I attempt to load a very large fact table in a SSAS Tabular
Model project using Visual Studio I receive the following error:
Memory error: Allocation failure : Not enough storage is available to process this command. . If using a 32-bit version of the product, consider upgrading to the 64-bit version or increasing the amount of memory available on the machine.
The current operation was cancelled because another operation in the transaction failed.
Visual Studio 2010 is only available in 32 bit and I have already changed the VertipaqPagingPolicy from the default 0 to 2, but still the issue exists. Has anyone experienced this before?

You have a couple of options in terms of removing the where clauses:
1) Build your project in SSDT and then use the Analysis Services Deployment Wizard to create an XMLA deployment script, then edit the script to remove the WHERE clauses before executing it on your server.
2) If this is a first time deployment change your project deployment options to "Do Not Process" - deploy your project and then edit the partitions for the tables with WHERE clauses to remove them.
3) Another option is to use views in your relational database. Then you can put the WHERE clauses in the views on Dev, but exclude them in the Prod database.

Tabular model process-took 4 HOURS instead of normal 10 minutes

There must be some sort of log I can view or review to get a better look inside the process?
When I refreshed my development project (which is using the same server for workspace) it takes less than 10 or 15 minutes.
Then I deployed it to my server and after 35 minutes I closed out of SSDT BI as it appeared to have frozen.
I then deployed again with no processing.
After that I processed manually through SSMS by using Process (but scripted out) for a process full.
After 12 or so minutes most everything appeared to have processed and the last feedback was on:
CREATE MEASURE 'PROFIT_WORKSHEET'[Less Cost Over Profit -Indirect Costs]=CALCULAT ..."
I could see that the SSAS server was still working via CPU activity, but no futher messages were reported to SSMS. Then after 3 hours and 45 minutes later it claimed to have completed and displayed:
"Execution Complete" (it had lots of white space above it, around 20 or so blank empty lines which was odd)
The tabular model seems to be functional, and it is less than 350 MB in size (almost the exact same size of my development workspace model) so I am at a loss as to why the delay like this?
Any suggestions, thoughts?
It returned 40 million rows, but I have other models that return more and process in 3 or 4 minutes so it is very odd (and it isn't 400 million, just 40 million)
Thanks!

Hi OneWithQuestions,
According to your description, you create a SQL Server Tabular Model project which takes 10 minutes to process in SQL Server Data Tools, the problem is that it takes 4 hours to process this database in SQL Server Management Studio. So you need the detail
log that inside the process, right?
In your scenario, you can enable SQL Server profiler to monitor the queries fired by the process, once you find some queries took a very long time to run, consider creating the smaller cube partition or optimizing the query by adding index or partition to
improve process time.

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'

SSAS Tabular - Vertically partitioned Fact Table Relationships

Hi All, I have a very wide (300 column) fact table and hence it is partitioned into 2 fact tables vertically with the common key in both tables for relation (1:1). Both the tables have some measures and degenerate dimensions to be used for analyisis.
How should the data model look like? I am stuck because the bi-directional relationships doesnt seem to be supported and only one direction works when degenerate dimensions are used.
Also, these two fact tables are related to some common dimensions and when i connect all of them together, some of the relationships get deactivated due to circular naure of relationships. Using USERELATIONSHIPS is going to be very timeconsuming considering
the number of measures.
What is the guidance around modelling vertically partitoned fact tables? Do I combine both the tables into one wide table using a View or Query? Any help appreciated.
Thanks, Ashish Singh

Hi Thomas, Unfortunately I do not have any control over the DW design and the client says that they require most of the columns for analysis. I do not want to combine the fact tables into a wider table but stuck with the relationship design in Tabular mode.
1) Bi-directional relationships are not supported. So, if both the fact tables have degenerate dimensions on which the mesaures have to be analyzed, it cannot work because the relationships are unidirectional in tabular mode.
2) Relationships get deactivated. Since both the tables are connected to each other using a KEY column, any attempt to connect both the tables to some common dimension results in INACTIVE relationships which needs either using USERELATIONSHIP or importing
the same table again with a different alias which complicates the model.
3) Inferenced relationships cant be modelled. If Fact1 is connected to a dimension, the measures of Fact2 cannot be analyzed on that dimension even though Fact1 and Fact 2 are connected using a 1:1 relationship.
All these design challenges make me lean towards using a SQL View and joining the 2 Fact tables in the Tabular model so that I could provide the users with the analysis they require using the current DB structure. Is there a different approach to achieve?
Any better ideas would be heplful.
Thanks, Ashish Singh

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.

Processing Tabular Model

1 We are developing a Tabular Model. In this model there are likely to be about 15 dimension tables and 2 main fact tables.
2 One of the fact tables is very large approximately 70 million rows and will increase to 150 million rows in about 2-3 years time.
3 So on the cube we have created partitions and are using the incremental processing. What we have done is to create a partition definition table header and lines. At the header level we will store the name of the measure group on which we wish to
create partitions, and in the lines table we will create the definition of each partition. Using an sp we will mark of those rows of the partition lines which we wish to reprocess. Such partitions will be dropped and recreated. So far this is working well.
4 I want to generalize this solution so that I works across different projects without any changes.
Now I have two questions :
Question 1 :
If I make changes in the tabular project and deploy the same, I believe all partitions will get deleted and all the data will need to be pulled in again. This will happen even if I add a calculated measure. Is there any method to overcome this ?
Question 2 :
What is the mechanism of only processing certain measure tables incrementally and all other tables fully ? In my above example only one table has partitions. So if I want to process only the current partition of that table, and all other tables how do I
achieve this ?

1) if you only add a measure or a calculated column, you do not need to read data from data source. If you have problem with deployment within VS, consider using Deployment Wizard.
2) A complete description of process strategies is included in a chapter of our book (http://www.sqlbi.com/books/microsoft-sql-server-2012-analysis-services-the-bism-tabular-model).
In general, you can control which partition/tables you want to process and in which way, using XMLA scripts, PowerShell and other tools. The easiest way to create an XMLA script is using the Generate Script feature in SSMS when you use the process wizard.

Data "chunking" in SSAS Tabular models

I have a Tabular model I built in VS2013, deployed to SSAS 2014 Tabular, and consumed via SSRS and PowerPivot. Let's say it consists of 4 fact and 1 measure table. The resulting dataset is about 10 million rows, which for some end-users can be a little unwieldy.
I had heard of "partitions", and thought it could help me "chunk" the data into manageable "user friendly" portions of the total measure dataset, but it doesn't appear to behave as I envisioned.
Imagine you have a model with world-wide sales information and you want to maintain that as a master model that you deploy, but want to make portions of the measure data available based on values in a fact table; let's say subsets that represent NA, another
for EU and so on. The geo data is a fact table in the model.
I envisioned "partitions" being select parts of the total model that you expose via partition name that the end user can select to work with like "I'm the AR for the NA region and this is my partition of the WW Sales data cube" How
would one accomplish this?

Hi Torben,
According to your description, you create a SQL Server Analysis Services Tabular model and deploy it to SQL Server 2014 server, and use Reporting Services and Excel to interact with this tabular model. Now the problem is that the resulting dataset is about
10 million rows, which for some end-users can be a little unwieldy, right? If I have anything misunderstood, please point it out.
In your scenario, you want to filter the data base on the user's region to improve the performance issue. In this case, please refer to the links below which describe how to achieve it.

http://grow-n-shine.blogspot.jp/2012/10/defining-row-level-security-in-ssas.html
Besides, to improve your report performance, you can cache your report. Caching can shorten the time required to retrieve a report if the report is large or accessed frequently. Please refer to the link below to see the details.

Processing of a deployed Tabular model inside SSDT

Hi,
operating inside SSDT, does it exist a manner to process a tabular model (or a table/partition) already deployed on the SSAS instance?
I know that it is possible to process only the workspace data.
Thanks

Hi Pscorca,
According to your description, you want to process data for a tabular model which had already been deployed on the SQL Server Analysis Services instance. When authoring your model project, process actions must be initiated manually in SQL Server Data Tools
(SSDT). After a model has been deployed, process operations can be performed by using SQL Server Management Studio or scheduled by using a script. So we cannot process data for a tabular model which had already been deployed on the SQL Server Analysis Services
instance.
If you have any concern about this behavior, you can submit a feedback at
http://connect.microsoft.com/SQLServer/Feedback and hope it is resolved in the next release of service pack or product.
Thank you for your understanding.

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

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.

If this is not what you want, please describe your dataset structure, so that we can make further analysis.
