    I'm having a problem with creating reports in CRM.

    After I construct a report, when I go to view the report, it says "Reporting Error, the report cannot be displayed"

    When I go into my CRM application server into the event viewer, I see that the fllowing error has occurred when I tried to run the report...

    Source: MSCRMReporting

     Web service request GetDataSources to Report Server http://<company>-crmsql/ReportServer failed with SoapException. Error: The path of the item '/<company>_MSCRM/4.0/' is not valid. The full path must be less than 260 characters long; other restrictions apply. If the report server is in native mode, the path must start with slash. (rsInvalidItemPath)

    So, I then go to reporting services web portal into the <COMPANY>_MSCRM-->4.0 folder and try to run a report directly out of report manager.  When I do, I get the following error...

    An error has occurred during report processing. (rsProcessingAborted)

          Cannot create a connection to data source 'CRM'. (rsErrorOpeningConnection)

              Value cannot be null. Parameter name: g


      Can someone please give me an idea of what might be happening here?

    I am guessing that something is wrong with connection string.

    So Download the report from MSCRM (go to Report screen --> Edit Report --> download report). this will be downloaded as .rdl file and then open this file in visual studio or notepad and check the connection string.

    it should be something like ...

    <ConnectionProperties>
    <DataProvider>SQL</DataProvider>
    <ConnectString>Data Source=MOSs;Initial Catalog=MicrosoftCRM_MSCRM</ConnectString>
    <IntegratedSecurity>true</IntegratedSecurity>
    </ConnectionProperties>


    if connection string is different then try updating as above and then upload report back to CRM (go to report screen --> Edit report --> select Report Type as existing file and then Browse to update file and save the record).

    hope this helps...let me know

    Ok, so what you recommended helped. I changed my connection and the report worked.

    Here is what the connection properties were before i changed them


    <ConnectionProperties><DataProvider>SQL</DataProvider>
    <ConnectString>data source=localhost;initial catalog=Adventure_Works_Cycle_MSCRM</ConnectString>
    <IntegratedSecurity>true</IntegratedSecurity></ConnectionProperties>

    Why is my connection string defaulting to adventureworks? Can I change this?

    I have this exact same connection string!  How can I fix this without downloading all the reports?
