Analysis Services Tabular Model 2014 vs 2012

Hi,
A very simple question : with the same tabular model is 2014 faster than 2012 from query point of view (is the Storage Engine or Formula Engine faster than the previous version ) ?
Thanks

Hi MIB1,
According to your description, you want to know if the SSAS 2014 tabular model has better performance than SSAS 2012 tabular. Right?
With exception to added functionality supporting Power View Reports against Multidimensional Models, SQL Server 2014 Analysis Services is unchanged from the previous release. There's nothing improvement on SSAS tabular.

How to get data from MySQL into Analysis Services Tabular Model

Hi,
I have a problem with Analysis Services Tabular Model and MySQL ... I have to use several MySQL databases as a source of Tabuar Model ..
Is there any way to get connection working from Tabular Model to retrieve data from MySQL database. I have a situation that in MySQL server there is several databases with same schema, one for each customer. I have planned to join these customer databases
to one Tabular Model, create roles and users for each customer to query their data.
What do I have to do to get this working ?
Pasi

Hi ,
In Tabular model out of the box there is no direct connectors available for MySQL. Please see the list of supported Data Sources
http://msdn.microsoft.com/en-us/library/gg492165.aspx
But i think if you can establish a ODBC connectivity with data source to MYSQL , you can use the ODBC connection to retrieve the data from MySQL. Please try this and post the results here if it is possible or not.

Memory usage in Analysis Services tabular model

Hello,
I've been researching and investigating trying to understand what is consuming memory resources in a tabular model that I'm working with. Using SQL Server Management Studio, the Estimated Size of the database is reported as 7768.34 MBs. Using
Kasper de Jonge's BISM Server Memory Report, the database is reported as 15,465.13 MBs. However, a majority of the fields in the BISM Server Memory Report are empty, and so I cannot determine what is consuming the memory. The data source for this particular
workbook is $SYSTEM.DISCOVER_OBJECT_MEMORY_USAGE.
For example: I drill-down to an individual column (ColumnA) in the BISM Server Memory Report (Database > Dimensions > Table > In-Memory Table > Columns > Column) and the reported memory usage is 706.97 MBs. Underneath ColumnA,
I see a blank level with a reported memory usage of 623.59 MBs and a Segments level with a reported memory usage of 83.39 MBs. Looking at $SYSTEM.DISCOVER_STORAGE_TABLE_COLUMN_SEGMENTS, if I SUM the USED_SIZE for ColumnA, it totals roughly 83 MBs which matches
what is reported in the BISM Server Memory Report for the segment size. How do I determine what the other 623.59 MBs is being used for? Again, this discrepancy occurs for all columns in the model and not just this one example.
Thanks!

Follow up to my original question. It appears that the blank levels (at least under the column level) the Kasper de Jonge's BISM Server Memory Report reports the dictionary size of the column. The memory usage size matches the DICTIONARY_SIZE attribute in
the $SYSTEM.DISCOVER_STORAGE_TABLE_COLUMNS. I made a mis-assumption as to what the information $SYSTEM.DISCOVER_STORAGE_TABLE_COLUMN_SEGMENTS was providing.
In my original post I reference one database in particular in where the Estimated Size property in the Database Properties dialog is listed as 7,768.34 MBs. and the $SYSTEM.DISCOVER_OBJECT_MEMORY_USAGE reports 15,465.13 MBs. Thoughts, comments, or opinions
on why the Estimated Size property does not match what's reported in $SYSTEM.DISCOVER_OBJECT_MEMORY_USAGE?
Thanks!

Hi Screeni,
In your scenario, you can to calculate for 1 Year rolling values from current date, right? In MDX, we can calculate it using Lag and ClosingPeriod function, here is a sample query for your reference.
WITH MEMBER [Measures].[Last 12 Mth Order Count] AS
SUM(
ClosingPeriod([Date].[Calendar].[Month], [Date].[Calendar].[All Periods]).Lag(12)
: ClosingPeriod([Date].[Calendar].[Month], [Date].[Calendar].[All Periods])
, [Measures].[Order Count]
SELECT [Measures].[Last 12 Mth Order Count] ON 0
FROM [Adventure Works]
Reference
Lag (MDX)
ClosingPeriod (MDX)

Non visual totals in Analysis Services Tabular

Are there any work-a-rounds to achieve non-visual totals in Analysis Services tabular? This is a crucial feature for some of our clients and is preventing them from adopting this technology due to this feature not being available out of the box
as with Multidimensional OLAP. If not, are there any plans to introduce this feature for Analysis Services tabular models?

Hi Geoff3c,
As you know SQL Server Analysis Services (SSAS) Tabular only supports visual totals. This is a differences between Analysis Services OLAP and Tabular that SSAS OLAP provides one feature that SSAS Tabular does not: non-Visual Totals. It was considered that
non-visual totals are not terribly common, but some developers have worked for clients where non-visual totals were required.
If you have any concern about this feature, you can submit a feedback at
http://connect.microsoft.com/SQLServer/Feedback and hope it is released in the next release of service pack or product. Your feedback enables Microsoft to make software and services the best that they can be, Microsoft might consider to add this feature
in the following release after official confirmation.

PowerPivot and Analysis Services tabular instance in SharePoint

Hello,
If I connect to the SQL Server 2012 SP1 Analysis Services tabular instance in SharePoint 2010 that houses all of the PowerPivot files that have been uploaded to our SharePoint environment, I only see a portion of the models
that exist. Why is this? What would cause a model on the tabular instance in SharePoint to disappear? Also, what does the “Sandbox” and “Process” preceding the model GUID mean?
Thank you!

Hi Haras,
According to your description, you need to configure PowerPivot for SharePoint on your site, right?
In this case, please use the following checklist to install these BI features in the same SharePoint farm: PowerPivot for SharePoint, Report Builder, and Power View.
https://msdn.microsoft.com/en-us/library/hh231687.aspx?f=255&MSPPError=-2147217396

Deploying SSAS Tabular Model (2014)

Hi,
I'm trying to deploy my model with Microsoft.AnalysisServices.Deployment.exe
This works locally, but when I try on our test servers then it does not work.
Strangely enough it tells me that it was all successful....
Exactly the same result locally as on test server.
but on my computer it is really deployed but on test server it isn't....
Any one an idea how I could debug this?
Kr,
Sammy

Hi Sammy,
According to your description, you are using Microsoft.AnalysisServices.Deployment.exe to deploy the tabular model. It can't deploy successfully on test server. Right?
In this scenario, since the Deployment Utility didn't throw any error when deploying, the deployment supposed to be executed successfully. Please confirm you connect the correct SQL Server instance. Also please try to deploy via command prompt instead of
using user interface. You can choose silent mode and it can generate a log file for your further analysis.

Question on Tabular Model 2012

Hi,
I need to hide certain columns for a user group but the same columns should be visible for another user group in the same model. The out of the box 'row level security' would not work for this requirement. I tried a modelling technique, by bringing
the 'hidden fields' to a table using the 'Blank' DAX function in a 'role' on the table that contains the hidden fields, but this hides all tables related to the table that contains the hidden fields.
As a last resort I am creating two models (1) model one with all fields visible (2) model two will hide certain fields. Basically model 2 is a copy of model 1, only certain fields in model 2 will be hidden.
To avoid reading the source data twice I am planning to update the model 1 and then synchronize model 1 with model 2 ( the one with hidden fields). My gut feeling is that if I synchronize model 1 with model 2, all the hidden fields in model 2
will become visible, as the metadata in model 2 will be updated with metadata of model 1.
As the number of users would be in hundreds, implementing a complex security layer might impact the performance if we try and implement such security on the same model.
It would be great if anybody can share thoughts on the probable solution and if the approach to 'synchonize' both the models would work.
Thanks
Bidyut

Hi Bidyut,
According to your description, you want to implement dynamic security for two group users, right? In SQL Server Analysis Services Tabular model, we can implement dynamic security using an external security table but we can integrate this security table into
the existing tables based on particular source data at production implementations. So in your scenario, you can store the users' information on an external table, and then implement the security through this table. Here is a blog which describes how to implement
it step by step, please see:
SSAS – Tabular Dynamic Security
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.

SSAS Tabular Model and browse with MS Excel 2013

I have a tabular model, It has an attribute with datatype and data format as "whole number". When I browse the model from excel and add label filter, it
does not work as expected.
When I specify greater than 180 as label filter, It gives following output:
My guess is that it is just filtering on first two digits "18" and not "180". When I copy these values in a excel sheet and create pivot table on top of it, hell it works fine.
Is this a microsoft bug? have you encountered something like this or I am doing some thing wrong?
I am using tabular model 2012 and excel 2013 or 2010.

Hi Itz,
According to your description, the filter not works fine in excel for a SQL Server Analysis Services Tabular models, right?
I have tested it on the local environment, we cannot reproduce this issue. As per my understanding, this issue is related to the settings of your tabular model. Does this issue can be reproduce in multiple servers in your environment? In that is
case, from a support perspective this is really beyond what we can do here in the forums. If you cannot determine your answer here or on your own, consider opening a support case with Microsoft. Visit this link to see the various support options that are available

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.

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.

When will Excel Support Tabular Model Table and Column Descriptions via Tool Tip or other display mechanism

I have noticed that SSMS supports tool tips for the Tabular Model (tables and columns) however Excel 2013 doesn't appear to. This is a very important feature to our end users.
Does anyone know when this will be supported?
Thanks

Hi Meyer,
According to your description, you want to use the tooltip function in Microsoft Excel for the SQL Server Analysis Services Tabular model, right?
I have tested it on my local environment (Microsoft SQL Server 2012 SP1 and Excel 2013), the result is that the feature is not supported currently. It's hard to say the detail date when this will be supported. If this feature is enabled, Microsoft will announce
it on the document.
Besides, 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. Your feedback enables Microsoft to make software and services the best that

Dynamic security using Security table in SSAS Tabular model

Hi,
Platform : SSAS Tabular model (VS 2010)
I need to apply Dynamic security using Security table(manually created) in Tabular model, Need to apply filter for 2 tables. I am able to
create roles in Tabular model using USERNAME() and LOOKUP() function it worked fine. But the problem is when i am trying to give full access for a particular column and limit the access in other column, it is not working properly.
Please find below table and guide me where i am falling short. In the Security table wherever you find ALL it means full access.
Security table
Login Name
Dim_Country
Dim_Customer
DOMAIN\User1
ALL
2
User1 should see all countries but Only 2,4 Customers
DOMAIN\User1
ALL
4
DOMAIN\User2
2
ALL
User2 should see all customers but Only 2,3 countries
DOMAIN\User2
3
ALL
DOMAIN\User3
ALL
ALL
User3 should see all Customers and Countries
DOMAIN\User4
1
3
User4 should see 1 Country and 3 Customer
ALL - means NO restriction
Numeric values indicate the Dimension IDs
Do let me know if further explanations required.
Thanks,
Sundar

Hi Sundar,
According to your description, you want to implement dynamic security using Security table in SQL Server Analysis Services Tabular model, right?
It is very common to have data security implementation in BI projects either at databases or Cubes and sometimes this security implementation and maintenance goes out of control due to the dynamic flow of business information. Here are some links which describe
dynamic security implementation at SSAS tabular model using an external security table, please see:
