Reporting Services XML Error

Question

Really annoying issue that I have spent a long time on. I shall switch into Software Testing Bug Report mode (from a past life) to explain it.

Scenario

• I have modified a SSRS report to work with a new database structure
• The report uses a stored procedure which takes 4 parameters
• One of these parameters has been added to work with the new database structure
• Stored procedure works perfectly in SQL management studio
• Query works perfectly in the query designer window of report builder

Expected Results

• I expect that the dataset will show the fields when expanded
• I expect that the report will run correctly

Actual Results

• No fields appear under the dataset in the Report Data Pane of report builder
• Report does not run
• I get the following error:

There is an unclosed literal string. Line 1, position 64737. ---------------------------- Response is not well-formed XML. ---------------------------- The attempt to connect to the report server failed. Check your connection information and that the report server is a compatible version.

Notes

I have tried everything I can think of, including searching the report definition for unclosed strings but no banana.

Has anyone else come up with this error in SSRS Report Builder?

Technologies Used

• SQL Server 2008 R2
• SQL Server Management Studio 2008 R2
• Report Builder 3.0
• Building report on my local machine running Windows 7
• Running report on SQL Server Remote Machine running Windows Server 2008

Thanks

I hope this is not too late. But to anyone who comes across this same question I had a similar issue and I resolved it by removing my tablix that was generated and was still referencing fields no longer available in my updated sproc.

All I did was to delete said tablix and regenerate it using the wizard and my issue was resolved. I would propose that you recreate whatever you are using to display the dataset.

If you cant find any malformed XML in your report definition I would check the data the stored procedure is pulling. If there is a <, >, or any other symbol that would break XML in the actual data this could cause you to get this error. Try pulling the report with a parameter that would cause no data to come back and see if you still get this error. If not then the problem could be in the data that comes back.
