Often when errors occur on the database or cube RSinteract and Reporting Services reports will fail with the following error: 

An error has occurred during report processing.
 Query execution failed for data set ‘dataset_0′.
  For more information about this error navigate to the report server on the local server machine, or enable remote errors

In order to see a better description of the error you can either RDP onto the server and run the report or…  

To enable remote errors in Reporting Services 2005 or 2008 run this statement in SQL Server Management Studio: 

Use ReportServer;
update ConfigurationInfo set Value = ‘True’ where Name = ‘EnableRemoteErrors’;

You then need to reset IIS

There are more options here: http://technet.microsoft.com/en-us/library/aa337165(SQL.90).aspx

And here: http://technet.microsoft.com/en-us/library/aa337165.aspx

So now if you re-run the report you can see it’s a data source error – a field name has been changed in the database:

An error has occurred during report processing.
 Query execution failed for data set ‘dataset_0′.
  Invalid column name ‘myNewField2′.

A while back I wrote a post about the “Unable to load client print control” error that Report Manager (and RSinteract) was throwing after Microsoft’s auto update KB956391.

I also asked a question over at StackOverflow which I ended up answering myself. Yesterday follow up information was added, which may be of use if you have trouble with the fix.

EY Kalman says:

I have had the same problem (on several different servers). Applying SP3 and Report Viewer SP1 has helped on some of the servers, allowing the client machines to connect and download the control with no problem. However, I have had one server that, even after applying the updates, when accessing the report viewer using a client machine, it was still giving me the error. On looking into the exact URL GET request that is being sent, I discovered that it is possible to force the client machine to connect directly to the Report Server to download the control.

The user would need to enter the following url:

http://reportservername/Reports/Reserved.ReportViewerWebControl.axd?ReportSession=51bjqv45xydgos2wghu5ceza&ControlID=7617dedbf0234f89b80cad8e64431014&
Culture=2057&UICulture=9&ReportStack=1&OpType=PrintHtml

This should then pop up the required download/install prompt.

dotnettrio added (which is probably more relevant to RSinteract):

Hi,

I got this working with out removing any patches. The above patch was not working too. Finally what I did was on the IIS server install the following patch and reset / restart the IIS server. This is not for report manager application. This is for any ASP.NET Web application developed in .net3.5 using VS2008 http://www.microsoft.com/downloads/details.aspx?familyid=6AE0AA19-3E6C-474C-9D57-05B2347456B1&displaylang=en

I hope this helps anyone else with this problem.

After 8 long years the browser that everybody loves to hate is being automatically retired by Microsoft. Although there is a way to avoid the upgrade if your business has the problems later in this post.

To be fair to it, IE6 helped make the web what it is today. Its quirks mode rendering enabled anybody to code a web page with little regard to well-formed HTML or standards. This caused many a developer to hate it because it renders things differently to other browsers and often caused a lot of extra work because it takes so long to get it working in both.

Most of the anger directed at IE6 has to do with the differences with the W3 Consortium’s standards. However, when it was released these standards were not concrete and it was unclear if they would even be adopted ubiquitously.

Many companies have ignored Firefox and stuck with IE6 because of the huge costs involved in deploying and testing all their internal applications on their networks.

RSinteract is Internet Explorer only and will continue to support IE6 and IE7 for the foreseeable future because of this very reason. The web is changing and more and more people are becoming aware of other browsers such as Google Chrome. Perhaps in future we will move towards cross browser support but for now we are very much tied to Internet Explorer.

On any software project it’s important for managers to have some sort of system in place to keep track of how long tasks are taking and how much time has been spent collectively on a project. Gathering this data is fairly easy (with the right tool), for RSinteract we have a TimeBooking application written internally that collects the data. It’s fairly simple: client, task, comments, lots of drop downs for each half hour slot in the day. It works.

The problem is getting this data in a useable form to make decision on… but wait! We’re making a reporting tool. What better way to look at our time booking data than in a nicely formatted report!

Here’s an example of my time as booked back in the second week of December. I’ve quickly made a weekly time sheet using our _Reporting view in the time booking database with filters for employee and week commencing. I can now save this and look at anyone’s time for any given week! Clever eh?

Using products internally like this is known in the industry as “dogfooding” as in “eats its own dog food”. This gives us a good idea of how our clients may use the software and also highlights problems that we might not otherwise pick up in our usual testing.

I’m just setting up RSinteract on a client’s 64 bit server which has Windows 2003 and SQL 2008. With most RSinteract installations IIS is installed as a prerequisite to Reporting Services but IIS isn’t needed for Reporting Services 2008. I guess this will become a common sticking point with SQL 2008 installations so here’s the solution…

The first problem I got was in the RSinteract installer (whoops, should have copied the error message) so we installed IIS and then RSinteract. When I hit the site I got this error:

The XML page cannot be displayed

Cannot view XML input using XSL style sheet. Please correct the error and then click the Refresh button, or try again later.

<%@ Page EnableViewState="false" Language="c#" ValidateRequest="false" AutoEventWireup="True" Codebehind="Main.aspx.cs" I…

I guess this is because IIS isn’t configured for ASPNET by default so I ran:

%windir%\Microsoft.NET\Framework\v2.0.50727\aspnet_regiis.exe –i

Which gave me the following error:

The error indicates that IIS is in 64 bit mode, while this application is a 32 bit application and thus not compatible.

So I made a slight change to point to the 64 bit .NET folder:

%windir%\Microsoft.NET\Framework64\v2.0.50727\aspnet_regiis.exe -i

After an iisreset I was now getting a 404 error from aspx pages, the final step was to open IIS (type inetmgr at the command prompt) and go to the “Web Service Extensions” node and enable ASP.NET v2.0.50727. Another iisreset for good measure and we’re now up and running:)

Here’s a quick demo of the new indicators feature. It’s a pretty trivial one but shows the potential.

Server Error in ‘/RSinteract’ Application.

Could not load file or assembly ‘Microsoft.ReportingServices.Interfaces’ or one of its dependencies. An attempt was made to load a program with an incorrect format.
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Exception Details: System.BadImageFormatException: Could not load file or assembly ‘Microsoft.ReportingServices.Interfaces’ or one of its dependencies. An attempt was made to load a program with an incorrect format.

Let us know if you like it or not by commenting!

Let me start by apologising for the lack of a post in the last week or so, I have been really busy with the new, improved version of RSinteract (sneak preview in the next couple of weeks, watch this space).

One of the issues we have experienced time and again with RSinteract is a scenario where the ReportServer/Database or Analysis services is on a different machine from RSinteract as demonstrated in the following diagram. The problem manifests itself as an authentication issue when Reporting Services tries to retreive information from the Database or Analysis server because Active Directory credentials expire after the first hop, in this case from RSinteract to Reporting Services.

Microsoft are calling this the “Double Hop” problem. The reason for Reporting Services’ and Analysis Services’ lack of integration out of the box is “in the interest of security”. Active Directory uses Kerberos under the hood which can be configured to pass credentials between web apps or not. To get this working with RSinteract or indeed any ASP.NET application you need to correctly configure Kerberos delegation.

I’m having trouble tracking down the steps for Reporting Services, the link I had has gone dead since I began writing this post

So here’s the steps to configure your Analysis Services (from Business Intelligence and Agile Development Blog):

1. Download and install the SetSPN utility (Either from the Windows Resource kit, or from http://www.microsoft.com/downloads/details.aspx?FamilyID=5fd831fd-ab77-46a3-9cfe-ff01d29e5c46&DisplayLang=en)
2. SETSPN is used to configure a “Service Principal Name”, which is required by Kerberos
3. Create a Service Principal Name (SPN) for the Analysis Services Instance (on the AS server)
4. (If AS is running as a domain account) setspn.exe –A MSOLAPSvc.3/
5. Configure Active Directory Settings
6. All users that are connecting to Analysis Services through the intermediate host need to be allowed to use Kerberos Delegation (”Account is sensitive and cannot be delegated” must be unchecked)
7. The “Account is trusted for delegation” setting must be checked for each user and each service account used in the process.
8. The “Trust computer for delegation” setting must be checked for each computer used in the process
9. Configure IIS Settings for the Virtual Directory hosting the application (or SharePoint site)
10. The Authentication must be set to “Integrated Windows Authentication” or “Basic Authentication”
11. The application protection level must be set to “High (Isolated)”
12. The impersonation level for COM+ must be set to “Delegate”
13. The COM+ application identity must be set to an account where “Account is trusted for delegation” is checked.
14. Connection strings must include SSPI=Kerberos
15. Connection strings CANNOT use IP Addresses
