Tabular model cube

Is it OK to call tabular model database as tabular cube?
~DBA and BI Developer~ MCSA 2012 Please vote for this Post if found useful

Hi Psingla,
Generally, we do not call tabular model database as tabular cube. As you can see, when connecting to a tabular database in SQL Server Management Studio and expand a tabular database, there is no cube inside the database. However, when connecting to a multidimensional
database in SSMS and expand a multidimensional database, we can see the cubes inside the database.

Ability to Filter within an idividual perspective in a Tabular Model (cube)?

I have a rather large Tabular model that I would like to use across 10 different reports as the requirements are identical, save for 1 aspect - the report goes out to 10 different companies. I need to be able to limit each result set by the individual
companies, however a normal filter in a pivot table won't work as I cannot have each company seeing the other companies data. I was hoping I could manage this via a perspective per company, but it doesn't look like you can limit or filter within the
perspectives. I am trying to find the best approach to accomplish this without having to build out 10 different tabular models to maintain. I welcome any ideas on this; my searching didn't yield good results.

You can do it in by
1) Create perspectives with only allowed dimension members (individual company names in your list). This is done when you are creating the Perspective.
2) Create a role for each company and in the allowed set for the dimension(company) only allow values for that particular one. So you will have one role per company.
3) Have you considered the option of Dynamic Security?
Please mark as answer, if this has helped you solve the issue.
Good luck :) .. visit www.sqlsaga.com for more t-sql code snippets and BI related how to articles.

Designing database structure and SSAS Tabular Model cubes

Hi.
I need to design a database and SSAS tabular models for my clients but I am confused which way I should implement it.
Data for all the clients is stored into a single database with unique ClientId for each client, such 15 tables I have under a single database which stores information about all the clients.
Task is to create a SharePoint Site collection for each client which will display Power View Dashboard by taking data from above database.
Till now I have created a SSAS Tabular Model for each client, XClientModel, YModelClient using BIDS and using SQL Queries to extract data for respective clients(select * from Table1 where ClientID="X") and using Power View external connection
to this model, have created Dashboard and other SharePoint information.
I am not sure if creating different Model is suitable or I should first separate data for each client into separate database and then create Model based on respective client's database.
Can Some one highlight pros and cons on using
SINGLE database with Multiple Tabular Model (One with Many) AND Separate Database with it's Model(One to One) ?
This is understandable but just putting it here........Imp Note: Data for X client shouldn't be visible to Y client on SharePoint.
Please let me know if further information is required.

Hi Sgms,
In your description, you said that all the clients information were stored in a single database, now you want to know which method is better, single database with Multiple Tabular Model or separate database with it's Model?
In your scenario, all the information were stored in a single database, why do you want to separate it or create multiple tabular model? If you create multiple model, then you need change the data source to create PowerView dashboard for each client. As
per my understanding, you just need create one tabular to load all the information. And then use this model to create PowerView dashboard. Using filter to display the information for each client.

SSAS 2012 Tabular Model Restarting

Hello,
We are having tabular model cube which is of 40GB. Every day we are processing this cube via SSIS, before processing it we are restarting the SSAS service(from scripttask) so that it will clear memory and cache.
But most of the time service restating is not happening properly and package is getting failed. Thereafter we need to start service manually and then again we need to run the package.
My question :
• Restarting SSAS service every day is really good practice ?
• Apart from restarting service what other approach is there?
Awaiting for your reply!
Thanks and Regards,
Santhosh Shasthri M R

Hi Santhosh,
You can troubleshoot why service restating is not happening properly by using the msmdsrv.log. Are there any error message on the log? Under C:\Program Files\Microsoft SQL Server\MSAS11.\OLAP\Log (this could be different for your server), there are 3 log
files that are generated:
msmdrrv.log
FlightRecorderCurrent.trc
FightRecorderBack.trc
The msmdrrv.log simply points to the other two logs. There might be some detail information for this error.
Besides, I don't think you need to resrart the server to clear memory and cache. You can clear Analysis Services caches with SSIS task by using XMLA command, and run this package before run package to process cube.

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.

Possible to exposer Tabular model over HTTPS on port 443?

I know how to Access OLAP Cube with Excel over 443 port.
Is it possible to Access Tabular mode over port 80 or 443 with Excel?
Kenny_I

Hi Kenny_I,
To access SQL Server Analysis Service tabular model remotely, we need configure the Windows Firewall for Allow Analysis Access. Generally, we open TCP port 2383 or 2382 for remote access.
Open TCP port 2383 when installing a default instance or creating an Analysis Services failover cluster.
Open TCP port 2382 when installing a named instance.
Please refer to the link below to see the detail information.
http://msdn.microsoft.com/en-us/library/ms174937.aspx
After we configure the Windows Firewall for Allow Analysis Access, we can connect to SSAS tabular database in EXCEL. In your scenario, you want to access it using port 80 or 443, there is no such a scenario base on my research. So why do you want to access
tabular mode in excel using port 80 or 443?

Tabular Models and Column Security

We have a tabular model that we need to implement column level security against and we continue to run into brick walls, as anything to do with role based security is centered around row level security (or filtering).
Our need is NOT for row level security, but hiding dimensional attributes based on who is viewing the model. In keeping with the popular sales data scenario's, please consider this:
Fact Sales
Customer Key
Item Key
Sales Amount
DimCustomer
Customer Key
Customer NameCustomerKey
DimItem
Item Key
ItemName
In the aboave example, let's say we would want our Sales Managers to see the VALUE in "Customer Name", but for our Sales Associates, we do not want them to see the value, either have the column hidden all together or at a minimum a value of "HIDDEN"
or "".
We have two roles (AD groups) defined: 1 for users allowed to see, the other for users NOT allowed to see. Our intention was to use role based security, but all it does is filter rows. So if we use that level of security, the user see's
nothing and 0 for sales dollars. If you are allowed to see the value, you see everything and all sales dollars.
What is needed is to have everyone see the sales dollars, but not everyone can see the names of the customers.
Though the above example is related to sales, we are actually in the medical field and dealing with some highly sensitive patient related data that needs to be regulated for obvious reasons.
Are there any idea's out there that could help us with this so we can continue with our tabular build out? Or are we looking at sticking with multi-dimensional cubes.
Thanks for your help!

In a SSAS tabular model, we can achieve row level security which you can see on the link below.
Defining Row-Level Security in SSAS Tabular database
Getting Started with Row Level Security
However, currently there is no a functionally to set column level security based on my research. So I am afraid you requirement cannot be done.

Cell Coloring using DAX in SSAS Tabular Model

HI All,
I need to implement background and foreground cell coloring in SSAS Tabular Model using DAX or any other feasible solution similar to what Cell Properties does with MDX which is supported by SSAS Cubes.
Request the gurus to help me with this problem.
Thanks

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 ?
Sanjay Shah

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.

Rename Fact dimension in tabular model

Hi there,
I have a small Question I wanna rename Fact dimension in tabular model I mean I was using Fact table as a dimension as well.
Fact Table: SaleOrder
Dimension: SalesOrder
So under measures it should display as Fact_SalesOrder and Under dimensions it should display as Dim_SalesOrder.
where I can rename this ? at the moment in the two places it is displaying as
SalesOrder
Thanks for your help

Hi Siva,
In your sceanrio, you can create a view on the fact table, and then import this view to tabular model as the dimension table, so measure group name with not duplicated with the dimension name. Besides, there are benefits in creating the cube from database
views that sits on top of the underlying fact and dimension tables. Please refer to the link below to see the detail information about it.
Benefits of Creating SSAS Cube from Database Views
Hope this helps.

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.

Updation of DAX in SSAS Tabular Model

Hi All,
I have a SSAS tabular model which has around 42 Dimension table and 10 Fact table each containing some thousands
of record.when I am writing some DAX on a FACT to get some measure ,its taking 10-15 minutes time to update one DAX.
I have to write more than 300 measures using DAX.Can anyone please suggest how can I speed up the updation process
in writing DAX.
Thanks in Advance.

Hi Sanjay,
According to your description, there are around 42 Dimension table and 10 Fact table each containing some thousands of record in your tabular model, so it takes 10-15 minutes time to update the calculation to server, right?
It's default setting to update the modification to server when change something on your tabular model, if the tables contain large data, it will takes long time to update. In your scenario, we recommend you to use Multidimensional database instead of Tabular
model when having large amount of data with complex requirements.
SQL Server Analysis Services (SSAS) Multidimensional model is used when having large amount of data with complex requirements. In order to improve query performance, there will be a cube doing heavy time-consuming processing and then synchronize it
to query cubes.
However, SSAS Tabular model is used when the data model is relatively simple. So for the large amount data model, we recommend to use Multidimensional database instead of process data on one server then synchronize it to query cubes.

Tabular Model question

Hi,
I'm starting to use SSAS tabular mode and have a question.
I created a model and named it Subscriptions and was now making a report to query it. However it was deployed as Model. I went to the project properties and noticed that the Cube Name was set to Model.
This means that I can only have 1 model per SSAS Tabular project? I tried to add a new Tabular model and it says I can only have 1 bism file in a project.
Thanks

It's a balance. Fact tables or subject areas that will be queried together or side by side should be in the same model. Unrelated subject areas can go in a different database if you like. Yes, you are balancing duplicating dimensions across several models
with the complexity of managing one huge model.

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

How to handle reference Flat File for Dimentions in Tabular model

I have 2 flat files, which are needed in creating one Country dimention.
In SSAS OLAP cube, I would import these 2 files to 2 staging table. I would ETL to one DimCountry table on DW.
How to do with Tabular model?
Should both Files imported to Tabular model and then Insert new Columns and DAX to create needed relationships?
Kenny_I

Hi Kenny_I,
According to your description, you want to know how to import flat files into SQL Server Analysis Services tabular model, right?
In your description, you said that "you can import these 2 files to 2 staging table, then ETL to one DimCountry table on DW in OLAP cube." Based on my research, the flat files are not supported as the datasource of SSAS tabular model. So you can import
these 2 files to 2 staging table, and import the tables into SSAS tabular model.
