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.

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.

How to have a Total dimension element from tabular model?

Hi,
I have a dimension in a tabular model named School. I created a parameter that has all the schools based on a DAX query dataset, however I would also like to include a Total element that sums all the schools. How can this be achieved? In SSAS OLAP I would
have an "ALL" elements, but I'm not sure how this translates into Tabular Mode.
Thank you

Sure, I am creating reports in reporting services. I am creating datasets to retrieve each dimension members that exist in the fact table to create parameters that will filter the data dataset.
Now imagine, I select a Year and then I want to be able to select an element like "all schools" to check the aggregate number of subscriptions instead of only 1 of the schools.

Tabular model column rename with special characters - ), *, /, +, %, [ etc

I am working in tabular model 2012. I have requirement to rename the column names with special characters like ), *, /, +, %, [ etc. When I try to rename in my model, it gives me below error:
I also tried renaming the columns after creating a new test model with no luck. I may have lived with this error however we have another tabular model which contains special charaters in the name. This makes me believe that there must be some setting that
I am missing.
I tried changing the column name in other model having some special characters and it takes it.
I have gone through this link#
https://connect.microsoft.com/SQLServer/feedback/details/802009/ssdt-ssas-tabular-column-name-with-special-characters
and
http://msdn.microsoft.com/en-us/library/gg492144(v=sql.110).aspx which says that special characters are not allowed in column names however I am able to do it in one of our
models then why not others.
Any help is appreciated! Thank you for you time.

Well Mr. Google helped me.. I got the solution:
Databases of a specific modality and compatibility level can have object names that include reserved characters. Dimension
attribute, hierarchy, level, measure and KPI object names can include reserved characters, for tabular databases (1103 or higher) that allow the use of extended characters.
How to change the compatibility, just right click on the .bim file from SSDT and go to properties and change the compatibility to 1103.
I hope this will help someone. :-)

How to create Date relationship with Fact and DimDate on Tabular model?

I have two tables in SQL Server 2014 SSAS Tabular model.
DimDate(defined as data table) have date column (format is 1.7.2010 00:00:00) This table have been impoted from AdventureWorks.
FactSales have SalesDate column (format is 25.03.2015 18:08:05). This table have been imported from Excel. Colums is defined as date in Excel.
When I set Data Type as date in Tabular I get error:
"Datatype conversion failed for table...Value:'25.03.2015 18:08:05'"
I have tried to create calculated colums like =DATEVALUE([SalesDate]) and =DATE(YEAR([SalesDate]),MONTH([SalesDate]), DAY([SalesDate])), but getting error.
What should I do so that I can create relationship between Date column?
Kenny_I

Hi Kenny_l,
According to your description, you fail to convert the data type into date after creating calculated column with expression. Right?
In Analysis Services, the tabular will detect the source data type to determine which data type can be converted to. If you want to convert a data into date type, no matter this data is from database or a file, you must make sure this data can be recognized
as a date in SQL Server. In this scenario, the format '25.03.2015 18:08:05' can't be recognized as date even you apply DAX functions. So please change the format of the column in excel like "03.25.2015 18:08:05".
PS: For testing, you can create a temp table and insert sample text into a date column, because the date format in SQL Server depends on the location selection when installing.
After retrieving data from data source and all values within column are correct format, you can change the data type into Date, and select the format you expect.
If you have any question, please feel free to ask.

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

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.
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

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

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.

Time Intelligence DAX functions are not working in Tabular model

Hello,
I've implemented a simple tabular model using SQL Server 2012 SP1 SSDT with a date dimension that has an active relationship with the date key in the fact table and has met the criteria for a date dimension to the best of my knowledge, i.e. no missing
dates, etc.
However, when I add a calculated measure in the VS project using any time intelligence function, i.e. =CALCULATE(SUM([NewPatientTotal]),TOTALYTD(DimDate[Date])), the calculated measure only returns the value of the current member, i.e. SUM(NewPatientTotal])
without throwing an error. This is happens for all time intelligence functions!
Are there any best practices that I've missed? I've scoured the SSAS forums to no avail.
Thanks,
Ben
Ben Lezin

You probably forgot to use the "Mark as Date Table" on the DimDate table.

Drill Across Functionality in Tabular Model

We've a situation.
We've a Tabular model which has 3 facts and few dimensions.
Out of the 3 facts 2 are about Account & Products.
Facts realated to acocunt of a customer. How many are active, how much is the current balance, how much was the balance at the start etc.
Product Fact is about different supplement products that a cstomer has. He/she may or may not have a supplement product. Now this has facts like how much the customer owes in different products, rebate amount etc.
Now they both have Dimension Account as common Dim.
Relation between Account & Product is 1-M. If an account has supplement product it can be 1, 2 and max 3. If it doesnt have, it is 1-0 :)
Problem we're having is that if we want to slice both fact by Account Dim attribute, we get only the accounts which have supplement product. Becuase I believe Tabular model works on INNER JOINS. In this case I want to have OUTER JOIN. Since
I'd want to have all accounts come through in the query and where i've matching supplement product then the fact for that products.
Any help is appreciated.

By default, Excel hides row with empty measures. You can change this setting at the pivot table level: right click the pivot table, choose "PivotTable Options..." and then in the Display tab check the "Show items with no data on rows".

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.

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.
Sanjay

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

Importing tabular Model

I'm not sure which forum to post this question. I have created a tabular model and I want to be able to pull data from the tabular model to populate an excel spreadsheet and then import the data into SAS. When I pull the data into the tabular
model the column names end up including the table name and the column name twice. I would need to go in a manual change all these names. Is there anyway to just get the column name?

Hi RACAND,
Do you mean that you got double table name and column name while import Tabular model data into PowerPivot data model? Please correct me if I have something misunderstood.
If so, this behavior is by design. When we import Tabular model data into PowerPivot data model, the column name will display with the UniqueName. Please refer to the table below:
Object
Example of Use:
Hierarchy
[Date].[Calendar Year].UniqueName
Dimension
[Geography].UniqueName
Level
[Geography].[City].UniqueName
Member
[Geography].[City].[Seattle].UniqueName
For more information, you can take a look at the following article:
http://www.databasejournal.com/features/mssql/article.php/3531636/MDX-Essentials-String-Functions-The-UniqueName-Function.htm
In this case, we should rename the column name what you want after import data from Tabular model.
