Best SSRS Data Source: SQL Or SSAS?
Jul 6, 2007
I have a vision of a beautifully interlocked Business Intelligence system in which I load dimensional fact tables through SSIS, build aggregations in SSAS cubes, and quickly and easily generate SSRS reports using the cubes as data marts.
I am now a month into trying to implement this vision and Reality is stomping all over it. Primarily, I am running into issues with the "cube as a data mart" idea. Each cube is taking up an additional gig or two of space, report queries against them seem to take longer than a straight SQL query against my fact tables, and I am running into serious problems trying to pass time-related calculations such as Year-To-Date to my reports.
Has anyone else tried setting up a BI system that uses cubes as the primary drivers for their reports? Have you seen any benefits to doing it that way? Or should I generate most of my reports through the SQL tables?
I'm nearing the point-of-no-return in choosing my final methodology, and any feedback would be greatly appreciated.
Thanks!

how to trigger report's refresh following its underlying SSAS cubes process?
I want to keep reports data updated at all times, especially when this happens while user is already browsing the report..
I don't want to set an auto refresh for the report every 5 minutes as my cube is processed only one time during the day...

I have a cube that tracks sales by sales rep. In this cube, I have dimensions for SalesRep, Product, and Region hierarchies. I also have a Time dimension that provides Fiscal Year, Fiscal Quarter, Fiscal Month, and Calendar Date; the Time dimension also has an attribute showing the first day of the year for any given date (our fiscal year starts on a different date every year).
I have a report that passes StartDate and EndDate parameters back to the cube, and provides sales numbers by Rep, Product, and Region for that given date range. What I would also like is a field that provides YTD sales through the EndDate parameter.
This is a piece of cake for me to implement against the SQL tables, but I am pulling my hair out trying to determine the best way to implement with a cube. Does anyone have any suggestions?
TIA

I've got a report that is using a cube as a data source and I can't get the report to show all the data. Only data at the lowest level of the cube is displayed. The problem is that most of the data I'm concerned with is at higher levels. There's no problem with the MDX. I get the correct results when I run the query.
I'm using a table to show the results. I've also tried a matrix, but I get the same results. I'm using SSRS 2005 and SSAS 2000.
Anyone have experience with this? Am I missing something simple?

I've been doing research on the web trying to find if it's possible to create a Report Model that is based on a Data Source that is NOT SQL Server and NOT SSAS.
Specifically I'd like to be able to build a Report Model on a Web Server (or multiple web services).
Does anyone have any information relating to this? Based on my research it looks like there's a few interfaces that need to be implemented (such as ISemanticModelGenerator, etc.).
I did find a post relating to using ODBC data sources for a Report Model and the recommended solution was Linked Tables in SQL Server or UDM in SSAS. Both cases don't look feasible for a Web Service-based Data Source.
Thanks,

Hi all,
I'm sure what I am trying to do is very simple - but I just can't seem to figure it out. I have a report based on a SSAS cube (SQL 2005). The report shows sales based on the dates the user selects from the parameter field (the date parameter field comes from a Y-Q-M-D hierarchy). This all works fine.
What I would like to happen is for the members within the last 3 months to be automatically selected so that the report automatically executes for the last 3 months.
Can anyone help or offer any advice. If possible I would like to achieve this using the GUI features so that power users can use the "plug and pray interface".
Many thanks
Matt

Was wondering if there was a best practice minimum permissions for creating a SQL login to use when setting up a new shared Data source for SSRS report manager?
Something along the lines of them being a data read for the DB and permissions to update tempdb?
Would have thought it not advisable to have the login be able to update the main db...

This is a question regarding the use of an XML data source within an SSRS sub-report. This is a two server configuration consisting of SSRS 2K5 and a separate file server exposing xml files over http, IIS 5.
Is it possible, and if yes how, to configure the xml data source to use the application pool identity instead of the current caller identity? I can not turn off impersonation within SSRS. I need to revert to use the W3WC, app pool, process identity within the xml data source. I do not want to configure Kerberos delegation and the file server€™s IIS virtual directory must be set for windows security.

Hi,
I'm new to SSRS but have a problem connecting to Oracle. I have placed my reports upon a reporting server but the shared data connection isn't working and I'm confused as to why. I have specified the name, connection type as "Oracle", set the correct user id and password for the credentials and the connection string as for example 'Data Source=oracleExample;Unicode="True"'. I also have set the correct entry in the tnsnames.ora file for this datasource, example:
"oracleExample =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = 12.23.45.23)(PORT = 3425))
)
(CONNECT_DATA =
(SID = oracle)
)
)"
Unfortunately I receive the following error when trying to connect.
"
An error has occurred during report processing.
Cannot create a connection to data source 'oracleDataSource'.
For more information about this error navigate to the report server on the local server machine, or enable remote errors
"
I'm mystified as to what the issue is. Any ideas? Would restarting the report server pick up the tnsnames.ora file? I have this working locally using report designer.
Any help, much appreciated.

Is there a command that can be used to set the account and password of an SSRS data source? I want to use a datasource that uses the option "(windows) credentials stored securely in the report server". The password for the account to be used can not be known by any humans (or we have to kill them after) so we want to set it programmatically. Is this possible via a command?

I'm attempting to use SSRS (2005) with my Oracle RDB database (old DEC RDB), using an ODBC driver. I am able to create a report, and view data, but I need to add some report parameters to filter the data. When I attempt to use parameters in the query, I either get a syntax error, or a message that my odbc connection cannot use "named" parameters, and that I should use "unnamed" parameters.
Here is a snippet of my sql query:
SELECT Application_Notes.Lease_Application, Application_Notes.Followup_Code,
<...>
FROM
Application_Notes Join
<...>
WHERE
(Application_Notes.Tickler_date >= {ts '2008-02-08 00:00:00'} AND
Application_Notes.Tickler_Date < {ts '2008-02-09 00:00:00'} )
The "Tickler_Date" field is a binary date field. The above syntax is pulled from a Crystal Report, which I am considering moving over to SSRS. Ideally, I would like the user to enter a single RunDate parameter, and have the query do the following:
Where (Application_Notes.Tickler_Date >= @RunDate and
Application_Notes.Tickler_Date < (@RunDate + 1 day) )
If the user has to enter two dates, that will be fine, but I can't seem to get past the errors.
Thanks,
Paul

I'm new to SSRS 2005, and having a very hard time getting something I thought would be trivial to work. It would appear that if you want to report from XML data, there are a variety of ways to do so.
I would just like to use a simple document that was created by serializing to disk. I don't even have a fancy query. Can someone help me with an start-to-end from which I can build upon and add complexity? Thanks.
C:XmlDataCustomers.xml contains a single Customers table; 3 Customer rows with an ID, FirstName, LastName. (I'll try pasting it as a follow-up).
My DataSource type is 'XML' and the ConnectionString is the simplest of URLs "C:XmlDataCustomers.xml". Credentials are set to 'none'. My suspision is that I am not even succeding at creating a valid DataSource. I don't know if it has to do with the XML, the location of the file, the syntax of the ConnectionString or what.
Assuming I get this right, I want all rows and all columns, so I assumed an empty query on the DataSet would be appropriate.
I've found a bunch of examples - but none seam to be this trivial - they all involve using a web service, embedded data in the query, or creating a Customer Data Extension (CDE) to provide the document. I've tried converting these samples to use my DataSource, but so far no luck.
Your assistance is appreciated.

I have inherited a SSRS setup and am trying to do some clean up. Problem is I cannot see the Data Sources Folder. I am setup as SA and SU on both the RS Server and SQL Server. When I go check the catalog in SQL db it does truly exist as well as a number of data sources in the folder that reports are currently using. How can I see this folder?

I want to run SSRS report directly by connecting Excel as a data source. The report runs properly from SSDT, but when it is run from Report manager, some users cannot access the Excel connection and the report execution fails. I am using SSRS 2012 and Excel 2010.I have created the ODBC data connection in SSRS and when I use 'Windows Integrated Security' option for credentials, the connection gets successful. But the problem is that all users does not have permissions to access the Excel inline, but they should get the report working.How can I store the credentials to access the Excel in SSRS with a specific username and password?

I cannot get this error resolve either for myself or any users, and I'm actually part of the Admin group! Furthermore, a user with whom I'm tring allow to view this report keeps getting prompted for their windows username and password. I thought that since this datasource was set to Windows Authentification that it would just pass it through?
I'm pulling my hair out at this point:

Hi All,
It's been a while since I post here. Anyway, I'm trying to call a SSIS package as my data source for SQL reporting service but I keep getting the error "Cannot create a connection to data source 'DsSSIS'.
My DsSSIS consists of the following in the connection string.
="/file c:FarmBillTesting.dtsx /Set Package.Variables[User::FilterValue].Properties[Value];" & Parameters!FilterValue.Value.ToString()
I have tried everything that I know to make this work but I have been able to do so. Any help from the group would be great.
Thanks

Hi,
I'm am writing a report in SSRS 2005 on a local PC that uses cubes in AS 2000 on another server as a datasource. I am using the Microsoft SQL Server Analysis Services Extension (OLAP9) to connect to the cubes using windows authentication. I can save and preview the report in visual studio and publish the reports on IIS on my local PC with no problems but when I go to view the report in IE, I get the following error:
An error has occurred during report processing.
Query execution failed for data set 'dataset'.
Unable to recognize the requested property ID 'ReturnCellProperties'.
Have read various articles on the net with no conclusive explanation.
I have seen another post on this forum that suggests using OLEDB for Analysis Services instead but if I do this it doesn't allow me to use the MDX visual query designer. Creating the report using OLAP9 then changing to OLEDB and pasting in the query code doesn't work so well either.
I went and read http://technet.microsoft.com/en-us/library/ms159219.aspx about data sources supported by SSRS 2005 and it should be ok.
I am using sql server 2005 with the latest service pack 2.
Any ideas?

Hi,
We are in the process of upgrading a SQL Server 2000 database to 2005. For the mean time, we're trying it out on SQL Server Express 2005. My question is, can reports in SSRS 2005 pull data from SQL Server 2000 in case both are installed side by side in the same machine and the 2000 version is the default instance while the 2005 express edition is the named instance?
Thanks a lot!

I am building a webapp that calls an SSRS instance to display a report based on another servers web service.I can make a call from the ssrs server using this in the RDL:
<Query>
<Method Namespace="http://machine/webservices" Name="HelloUser">
               <Parameters>
                               <Parameter Name="user">
                               <DefaultValue>Craig</DefaultValue>
                               </Parameter>
               </Parameters>
</Method>
<ElementPath IgnoreNamespaces="true">*</ElementPath>
</Query>
This works no problem. but.. I want to have the user parameter "Craig" be a parameter passed in from the web app. If it were a regular SQL data source you would put @user in the query. How do you do it with XML text queries?

Hi,
I'm using SSAS 2005 cube as Data Source for my SSRS 2005 report. The report has parameters as well.
The requirement is that I want to pass parameters to the report using my own UI.
My questions are:
1. "How to pass parameters to my report using my UI?" I'm developing the UI using VS2003 (the client's requirement).
2. Is there any ReportViewer control available in Framework 1.x?
3. I'm also using a drilldown sub-report with the same report. I'm passing parameter values to the sub-report selecting the fields of my data. But when the sub-report is opened, it gives an error saying "The parameter 'X' is not assigned a value".
Can anybody help on any or all of these?

Thanks in Advance,

We're setting up a test and development envorinment and would like some advice on the best deployment of the SQL 2005 components.
Some people seem to advise to have
Machine1 SSIS & Database engine
Machine2 SSAS
Machine3 SSRS
Others say it's OK to put SSRS & SSAS on same box.
Others say it's fine to run all on one box.
Anyone have any rule of thumb advice or links to such ?
Cheers,
Will

We are running Reporting Services 2008 R2 on a Windows Server 2008 Standard 64-Bit server. I have a user that has full access to Reporting Services at all folder levels but IS NOT a local administrator on the 2008 server.

I have a measure in a SSAS cube that uses AggregateFunction "Sum". Dimension usage seems to be right so that it sums correctly.
But when I try to use same measure in SSRS report it comes out all wrong.
TO be precise the measure is called "CalendarDays" and it's the number of days in a month (28,29,30 or 31). Say I have 5 products and 4 years, If I look at this in the cube browser then the CalendarDays column aggregates correctly to 365 or 366 for each year even with the five products and 12 months in the rows.
However if I do a SSRS report by product and month with subtotals of years, then SUM(CalendarDays) adds up all the CalendarDays for each month and each product (ie 5 x 365 or 366). If I leave out "SUM" and just enter =Fields!CalendarDays in the subtotal then it doesn't aggregate at all, it jsut gives the first value (ie 31).
How can I get SSRS to aggregate the same way as the cube?

Hi
I've made my Cube having two language support - Japanese and English. For that I'm keeping two description columns relavent to language and mapping in dimenstion attribute translation. Till that it is fine. In SQL 2005 Analysis Services Browser it working very fine. But when I use this cube with SSRS, I've made Custom parameter for Language. And based on that I'm chaning Report.Language property for the selected language. It is working fine in case of Report Data. It is converting data in Japanese when I select Japanese Language and translating in English when I select English. But Problem is that Parameter's data is not chaning when I change the language. I supposed to that when I'm changing Report.Language to Japanese then Parameter's data should be changed in Japanese. Please help how it can be possible.
Thanks in Advance.
