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

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.

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

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:

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.

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.

Optimize Fact tables in SSAS Tabular Model

Hi,
I have five Fact tables in SSAS Tabular Model and each fact table share same dimensions. It creates some performance issue and also the data model looks very complex is there any simplest way to create simple data model using all fact tables. For Ex...
Please suggest me for this ...
Fact Tables:
Fact_Expense
Fact_Sale
Fact_Revenue
Fact_COA
Fact_COG
Dimensions:
Dim_Region
Dim_Entity
Dim_Product
Dim_DateTime
Dim_Project
Dim_Employee
Dim_Customer

Hi hussain,
Please consider merging the Fact tables based on granularity. Generally, if you have enough RAM there will be no performance issues. Make sure you have double the amount of RAM to cater your processing and operational needs.Try
to optimize the model design by removing unused keys and some high cardinality columns.

SSAS Tabular model conection stops refreshing data for sometime

Hi,
I am using SSAS Tabular model and create connection files to use data with excel using powerpivot or powerview.
But recently for 1 or 2 months it stops working for few mins (generally 20-60) and starts working again.
It's happens for all 4 SSAS service on same server.
I am using AD roles with SSAS Tabular model to filter the data.
Everything is normal no event for this stop, no network error, no over usage of data.
ERROR is:
Errors in OLEDB provider. Could not connect to the redirector. Ensure that the SQLBrowser service is running on the 'ABC_Production' secver.

Hi pinaKPatel,
According to your description, you get the above error recently when using your tabular model. Right?
Based on the error message, firstly, please check if the OLEDB provider is installed properly. Then check the SQLBrowser service is running. If everything is working, it may caused by the port blockage. Please follow the steps below:
Use a fixed port and unblock that port in Windows Firewall. Connect to the server in this format: <servername>:<portnumber>.
Use dynamic port assignments and SQL Server Browser service. Unblock the port used by SQL Server Browser service in Windows Firewall. Connect to the server in this format: <servername>\<instancename>.
Use a fixed port and SQL Server Browser service together. This approach lets you connect using this format: <servername>\<instancename>, identical to the dynamic port assignment approach, except that in this case the server listens on a fixed port.
If the issue still persists, pelase redeploy your SSAS database.

Evaluation of hw features of a machine hosting a SSAS Tabular model

Hi,
on a machine I've deployed a SSAS Tabular model that has two fact tables having each 200-300 millions of rows, and about 10-15 dimension tables. I've implemented some Excel workbooks, each of them queries one measure of one of the two fact tables.
Each workbook has 10-15 filters/slicers. I've tried some times to reduce the number of filter/slicer or of row expansion and I've registered a query response time from 5 to 15 seconds for a change selection for a filter/slicer. 15 seconds is a time too high
for the user requirements.
The formula for the two measures has some SUMs and DIVIDEs. In order to improve the query performance I've tried to write the formula in different manners and I've created partial calculations in the underlying dwh but with negligible performance improvements.
Cutting filters or slicers or row expansions is against the user requirements.
I've also captured some Profiler traces but with few indications.
I suspect that a possible issue derived from the hw features of the hosting machine. During the use of the pivot table the usage of memory is about 50-60% and the usage of CPU is 80-100%.
With the CPU-Z program I've captured the hw features:
I hope in any suggests deriving from the experiences and not from some papers, fe "Performance Tuning of Tabular Models in SQL Server 2012 Analysis Services", in order to improve the query performance from Excel connected to my tabular model.
Probably, the CPU features are not appropriate.
Many thanks

Hi Pscorca,
Based on your description, you want to if it is best practice for improve the query performance in hardware level by increase RAM or CPU. In this case, here are some document about it, please refer to the links below which might helpful for you.

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.

Change PowerView datasource from PowerPivot to SSAS Tabular model

Hi all,
I'm playing around with PowerView at the moment and use the PowerView examples provided by Microsoft. These are all based on PowerPivot with data from an access DB. Now I want to have the sample data not stored locally but on the server. What I did so far
was importing the PowerPivot into a SSAS Tabular Model (with the VS wizard) and published the model to the SSAS Server. So far so good, I can browse the data in the model.
However, I have not found a possibility to change the data source of the PowerView from PowerPivot to the SSAS Tabular Model. How can I do this? Or is this not possible?
Thanks,
Pascal

Hi Pascal,
Power View only supports Microsoft BI Semantic Model (BISM) for Power View data sources. BISM files are designed specifically for connecting to Excel workbooks and SSAS tabular models. The Excel workbooks can be in the PowerPivot Gallery on a SharePoint
site or in a SharePoint library. In this issue, you can publish the PowerPivot workbooks to a SharePoint library or the PowerPivot Gallery, and then create RSDS file or BISM data source to the workbooks. Here are the connection string samples:
An Excel workbook in Shared Documents on a SharePoint site:
Data Source=”http://<SharePointSite>/Shared Documents/MyExcelWorkbook.xlsx”
An Excel workbook in the PowerPivot Gallery on a SharePoint site:
Data Source=”http://<SharePointSite>/PowerPivot Gallery/MyExcelWorkbook.xlsx”

Migrated data from Powerpivot to SSAS tabular model, can i change the Excel source to SSAS?

Hi
I have developed some powerview reports in Excel/powerpivot files. Now, i have migrated powerpivot data from these files to SSAS tabular cubes. The question is if i can change the source of the Excel files, to "feed" my powerview reports
with these SSAS Tabular cubes, or do i have to create my powerview reports again via new Excel files or PowerBI designer (and "point" these to SSAS Tabular cubes). It totally seems not logical and so i think that's a good question.
Kind regards

SSAS Tabular model Performance Issue

Hello,
We have strange behavior with SSAS tabular model. The Model size is approx. 40GB in memory. Our production server has 200GB memory. Most of the users access the cube via Excel 2013 (64bit). We have been noticing that the performance starts degrading from
the next day after the Analysis service has been restarted or the server rebooted. The day either one of them is performed we get good response but then the next day response times becomes 2 to 3 times more than on the 1st day. Is this something which anyone
else has experienced. We are entering in a mode where we are required to restart the service almost everyday.
Any help in this matter would be greatly appreciated.
Thanks
Deepak

Why are you sure role based security is the culprit? Immediately after cube processing or immediately after ClearCache does the report perform fast for a user without any role based security filters? I would recommend reviewing the methodology on page
35 of the tabular performance guide to see if it is a storage engine or formula engine bottleneck and report back.

Error about using a concatenated calculated column in a SSAS Tabular model

Hi,
in a my tabular model I've added in a dimension table a calculated column concatenating a code and a description. The code is used to create a relation between a fact table and this dimension table.
When I try to use the tabular model inside Excel and select the concatenated column as a filter I've this error message:
I've tried to recalculate some times the tabular database after the deployment of the model changes and I've tried to run a full process of the entire database but any results.
Any suggests to me in order to solve this issue, please?
Thanks

Hi, I've solved. The concatenate formula was with "+" operator and not "&".
But during the column creation I've any errors also if the model in SSDT was empty.
Bye

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.
