Analysis :: SSAS Tabular Model In DirectQuery Mode Clients
Jun 27, 2015
I'm working on a Tabular model at my job since the users have a requirement to query against a live data source. I've been looking online for clients that issue DAX as opposed to MDX to the model, but besides SSRS and Power View, I could not find anything else. Any other client side interfaces to a DirectQuery Tabular model?
I have a new 2014 SSAS installation. During VS2013 Tabular Project create I get an error Cannot connect, Reason The workspace database on server ***** is not running in tabular mode.I've changed msmdsrv.ini - DeploymentMode>2...The server wont start.
I get the following error while processing a SSAS tabular model (2014) on a new server.The SSAS service on this server is running under a login which has access to the SQL server data sources. I tried changing the provider to OLEDB from SQLCLNI11 in the connection string but that doesn't work too. The error message isn't useful to debug further.
The cube processing succeeds on a different server. I scripted out the cube DB and ran it on the new server and am trying to process full but it fails with the following error.
Error Message: The operation failed because the source database does not exist, the source table does not exist, or because you do not have access to the data source.

We are working on implementing DAX formula(s) on our tabular model (SSAS 2012). When we tried to deploy the solution, deployment wizard giving us then below error:The given key was not present in the dictionary...I checked all the formula(s) that we recently implemented and all looks fine.
I have a separate date dimension marked as Date table in Tabular Model and having proper relationship with another table(e.g SalesTable) with column of date type. But still time intelligence functions are not working. I am using the date column from other table (e.g SalesTable) in the formula. What exactly going wrong in our tabular model.
Can applications connect to SSAS Tabular mode cubes through ODBC drivers? I have been asked the question specifically regarding SAS, and I can see (for example) SAS Enterprise Guide has the ability to connect to sources via ODBC, so I now need to find out if there are such things as ODBC divers for SSAS (specifically Tabular).
I am trying to learn building SSAS tabular model. While following a tutorial I need to add a column to an existing table but for some reason the ADD Column option (insert column in other menu is also not appearing) is greyed out.
SQL Server Data Tools within VS 2010 Shell.2012 SASS in Tabular Mode.I've created a Measure and KPI in my fact table. I've created a perspective named "Summary" When selecting the fields and measures for display in the perspective, the measure is available, but not the KPI (target, status, etc.). When Analyzing in Excel with the Summary perspective, the KPI is not available in the field list. When analyzing in Excel with the (default) perspective, the KPI is available.As far as I can tell, there is no way to select a KPI within the perspective window.
I am working with SSAS Tabular. I have a stand alone table with 60 columns and contains 120K records. Table size is 250MB. And trying to build a tabular report out of it and it is taking longer and throwing exception, screenshot attached.
It might be cross-join issues, as workaround created a dummy measure and using in report. But it working for 10-20 k records and beyond throwing same exception. I have 8 GB RAM and 100 GB free disk space.
i would like to pose a question, when a user do a login in SSRS server,is it possible to pass the username to SSAS tabular, to implement security? I've tested using USERNAME() creating a role that relates USERNAME() with a dim user username, but now i need to implement it with the username used in SSRS server.
I have a Tabular data model and I'm returning a measure that counts employees (each row is an employee) and then a calculated column in the model that gets SeniorityInMonths.
So if an employee was hired exactly 1 year ago, they would have 12 in this column.
I want to group these into bins, but the Group option is grayed out.
I have a Tabular model, it has 8 tables , 7 of the tables process in 3 mins, but the main table is 22.3gb in size//I am processing the table on a 64 bit pc with 8 gb ram to the local instance from a Production server//At this rate it will take days to process the Main table 22.3gb, the main table was running off a view but I have inserted the data into TableA and updated the model///Only other optimization process I can think of is copying TableA to my local machine but the performance to the Server on the network is not an issue.I am just process the main table for the last 4 hrs and it is only at 11.7 mill records out of 124 mill total @ this rate it will take 44 hours
I have created a tabular model with VS 2013 Ultimate. I deployed the model several times and everything works great with Power Pivot.
One of the dimension tables, "Age", has an integer field that is null. I updated that column in SSMS to have values, processed the table in VS and the "Age" column now has integer values.
I deployed the model again, connected with Power Pivot, and the "Age" column still has not data. I refreshed the Excel spreadsheet several times, started a new one, deployed several times and there is still not data in the "Age" column even though it clearly exists in VS.
I opened SSMS on the Analysis Service and queried the table in question and it also shows no data in the Age column even though it is in the data table and the VS model.
I can't find anything different about this column than others that contain data. How can this be happening?
Is it possible to install 2 SSAS instance (one default and one named) and have them access a single sql server instance (default) all on the same server?
I have two different roles, each one with a dax filter. One is for filtering users that access by Excel, and other for filtering users that access by Reporting Services, respectively:
To create only one role that serves Excel and Reporting Services users, is it viable to use only the || (OR) operator?, is there any other regard i should take?
We have a requirement to convert Tabular model to Multidimensional as few functionalists like actions does not support in tabular. Looking for list of things needs to take care to convert tabular solution to Multidimensional.
I have been looking at implementing a tabular model based on an OLTP database that's not dimensional. I know that this is possible but during my proof of concept I have encountered numerous problems ...
The things that I have run into are: After setting up the relationships I have found that measures filter context don't propagate along the relationships as I would expect. if the measure is coming from a target table and not a source then an ALL member is returned ( as in multi dimensional when a dimension isn't related to a measure group). Given the lay out of an OLTP database this will be hard to avoid.
One thing I have done to try an mitigate the above problem is to combine the tables used for measures in a view and using that in the source to connect to the rest of the tables. however due to the tables being of different grains this has then created duplication in some of the keys and measures. so the keys cant be used in relationships and the measures aren't accurate.
Are these things other people have come across? or should I give up the ghost and just recommend using dimensional models for the source? is tabular just geared towards a DW the same as multidimensional?
If user want to see the grand total for a measure with include all members, even though the user has limited access for that member, so how we can do using DAX?For example, let’s say the total revenue for all the divisions in a cube is $15,000. You create a role called “Division A”, and set it up so members of that role can only see the revenue for Division A, which totals $3,000. If you use a front-end tool like Excel to access the cube and use the division hierarchy to see the total revenue, you will see the revenue of $3000 for Division A, but also want to see the Grand Total for the revenue as $15,000How we can achieve above scenerio in tabular model (DAX).
I created a model in Visual Studio 2012 and when I process the model, most tables (the ones that should) process 77,546 records and that is reflected in VS.
However, when I deploy the model to the server it is only deploying 76,500 records for those tables.
Where those 1,046 records went to? Is there a setting that limits the records to be deployed? My base tables in the Data Mart have 77,546 records, just as in my Visual Studio model.
I built my first tabular model and see that my fact tables are also appearing as dimensions. In Multi dimensional mode i could choose which are the dimensions. How do i do that in tabular model.
I have a very small SSAS database with around 35 Mb. I opened it on Excel 32 bits and started dragging fields to a pivot table and it started failing with memory errors. The behavior on the SSAS server was that memory started growing very fast until 8 GB (vm memory total) and then the error is reported in excel.
What might be the issue in such a small database? I would understand in a big database, but not on this one.
I am thinking of a possible design where the cube will never go offline.
Usually when I do some code changes on my cube the cube goes offline and I need to Full Process it again to get it back .
However , in cases where the cube is extremely critical for the business users , it would be great if I can deliver a solution where the cube never goes down.
I am receiving the following error when I run the report builder query. I am able to successfully select the dimensions and measures that I am intrested in but when I run the report I get the error message.
The 'PerspectiveID' custom property for the 'query' perspective is either not set or is not set to the string data type. ---------------------------- Semantic query execution failed. ---------------------------- Query execution failed for data set 'dataSet'. ---------------------------- An error has occurred during report processing.
I am testing this against both Adventureworks standard and enterprise cubes. Additionality I saw a post in this forum http://forums.microsoft.com/MSDN/ShowPost.aspx?PostID=368962&SiteID=1 that seemed related but I am using reporting services in sharepoint integrated mode so I am having a hard time trying to troubleshoot this.
I am trying to implement some powerview report in excel 2013 itself (not in sharepoint).
I have implemented a SSAS tabular model and deployed to server. Now my aim is to load this tables in the SSAS tabular database into powerpivot so that i can use this data for creating powerview reports. However when i tried to import data from SSAS, it asks database and MDX query. My requirement is to load the dimension and fact tables to power pivot as it is.
We have an Excel PowerPivot model that we are trying to move to SSAS Tabular. The model is complex and has over 300 measures. To group these in Excel, we pasted in dummy tables and defined the measures in logical groupings. Now when we are migrating to SSAS, we have to delete the pasted tables --that have ALL of the measures, in order for the import to work successfully.
How to migrate the model? We have a nice report of all of the measures from DAX Studio, but I am not looking forward to manually re-entering 300 measures through the user interface. Is there any way to define measures in batch? Or is there a way to change the pasted table to a file so the import will work? Will the import work in SSAS 2016?
I have a question about partitions in both SQL Server table and Tabular Model. I started to use Tabular Model recently.
I need to partition a table that collects daily rows for different clients.
The natural partition key is a combination of clientID+dateID (something like CL-YYYYMMDD)
I created a configuration table with a primary key PartitionID IDENTITY(1,1) , that contains also the field clientID and dateID
Every day I add a new row in it and I get a partitionID for the new client and date
Then I created a partitioned fact table using PartitionID as the partition field, using the partition function and the partition schema as well.
The daily client data is inserted in the partitioned table using the partitionID
Everything works fine, and the data are loaded correctly into the partitioned fact table.
Then I created a Tabular Model where the fact table is the partitioned table, and I created tabular model partitions using something like "select <field list> from PartitionedTable where partitionID = <partitionID>"
In this way, every day I load partitioned data in both sql server and tabular model. I have two dimensions, client and calendar
Now my question is: when I browse the Tabular Model, and I'm selecting a specific dimension date and dimension client, am I using the partitionID index correctly?
Or should I put in the tabular model partition query something like "select <field list> from PartitionedTable where clientID = <clientID> and dateID = <dateID>"? In this case is still working the partitionID index? How can I check it?
i have a model contains fact of account revenue , a time dimension and scd of account.
the scd (type 2) is changing when an account get a new color.
when i queries the model by PowerPivot i sometimes get wrong color for an account in a date priod , for example , I would expect to see color 3 for account 1 at 04-06-2010 , But instead I see color 1 - as you can see in the picture bellow.
FACT , SCD :
Result
i process all , deploy , mark dim_time as date dim , and i still cant find the error.
I have a ssas tabular model as a data source in a .pbix-file. I have uploaded the .pbix-file to Power BI Services and it works fine as long as my visual studio project is open. If I close my visual studio project, the objects in Power BI Services will say "The data recievement for this visual information was not successful."
I have been living in the T-SQL world for years, and am working on my first Tabular model.
I have a fact table that I would like to use for many reports. My idea is that I would use Perspectives in the tabular model to pull in the columns that I need for each purpose. In some cases, I also need to filter out some rows. Is there a way to filter perspectives? The only solution I am coming up with is to create views in SQL Server and import the fact table multiple times for each purpose. That doesn't seem very efficient.
