SSRS the definition of the report is invalid

How can I resolve the below error message that I receive when I try to deploy my report to our our Reporting Server using BIDS?


  • Inter-column uniqueness constraint
  • Why do I get no results when returning the results of a Stored Proc?
  • SQL Server CTE -Find top parentID forEach childID?
  • Group by Time Interval
  • Deploy Failed : CLR Trigger
  • Dynamic pivot with Max(Date) from pivot
  • Error : The definition of the report ‘/OrderAnalysis’ is invalid.

    Report Element:

     <Report xmlns:rd="" xmlns:cl="" xmlns="">

    I just received this obscure message when trying to deploy a report from BIDS.

    After a little hunting I found a more descriptive error by going into the Preview window.

    I found the problem to this… due to a incorrect/failed reference in .rdl to data conns etc. Also found that BIDS wasn’t happy about having spaces in some of the project/report filenames… so anyone facing this issue make sure you have no spaces in your naming and check your rdl files, connections, everything for failed/out of date references! Visual Studio seems crap at keeping all of it’s references up to date… god forbid you have to rename anything!

    I had simply changed the capitalization of ONE character in one of my report parameters and could no longer deploy. Changing the single character back to uppercase allowed me to redeploy.

    I just had this same problem during a SSRS development of a Custom Report for MS CRM Dynamics 2011.

    The reason because it occurred is because I am using some Hidden Parameters and for some of them I forget to give a default value.

    So, because of I have few time to finish the report I forget to put the default value for some Parameters and I risked to lost more time to fix it.

    Luckily I found it very fast because the error shows the textbox and the paragraph with the first wrong parameter but it didn’t shows the name of the parameter:

    “I cannot post the image of the error because this website don’t allows me”

    In general during SSRS developments it’s very important to remember:
    – To put the report parameters in the correct sequence (the referred ones for first es. parameters inherited from master report or parameters essentials for sub-datasets)
    – To assign a default value to the Hide and Internal Parameters.

    This occurred for me due to changing the names of certain dataset fields within BIDS that were being referenced by parameters. I forgot to go into the parameters and reassign a default value (the default value of the parameter didn’t automatically change to the newly renamed dataset field. Instead .

    A very cryptic message for what my issue was.

    I had changed the names of the parameters, but did not update these names in the dataset.

    I just ran into this issue as well. There’s an option to “refresh fields”, which I found useful. What I didn’t find intuitive at first was that one has to enter values used to execute the query in such a fashion as to refresh the fields. Once I figured this out, and refreshed the fields – things worked. The data sets and the shared dataset that’s being called have to correlate.

    The report definition is not valid or supported by this version of Reporting Services. This could be the result of publishing a report definition of a later version of Reporting Services, or that the report definition contains XML that is not well-formed or the XML is not valid based on the Report Definition schema.

    I got this error when I used ReportSync to upload some .rdl files to SQL Server Report Services. In my case, the issue was that these .rdl files had some Text Box containing characters like ©, (Em dash), (En dash) characters, etc. When uploading .rdl files using ReportSync, I had to encode these characters (&copy;, &mdash;, &ndash;, etc.) and use Placeholder Properties to set the Markup type to HTML in order to get rid of this error.

    I wouldn’t get this error If I manually uploaded each of the .rdl files one-by-one using SQL Server Reporting Services. But I have a lot of .rdl files and uploading each one individually would be time-consuming, which is why I use ReportSync to mass upload all .rdl files.

    Sorry, if my answer doesn’t seem relevant, but I hope this helps anyone else getting this error message when dealing with SSRS .rdl files.

    I was getting this error and tried most of the suggestions here. Finally I did a “Clean” on the report project and tried again. It finally worked!!

    I got this error on a report I copied from another project and changed the data source. I solved it by opening the properties of my dataset, going to the Parameters section, and literally just reselecting all the parameters in the right column, like I just clicked the dropdown and selected the same column. Then I hit preview, and it worked!
