SSRS - Max request length exceeded RRS feed

  • Question

  • First off, I have changed web.config in the MSRS12.MSSQLSERVER\Reporting Services\ReportServer with the code....

    <httpRuntime executionTimeout="9000" maxRequestLength="2097151" />

    I restarted the report server service. This does not seem to fix it, as I'm still getting the same error everytime I try to upload a 20 meg rdl. Everything I google returns the maxRequestLength fix. Is there anything else I can try?

  • Hi mmohon,

    According to your description, when you upload a 20 meg .rdl file to report manager, the error message “Max request length exceeded” throws out, right?

    Regarding the error message, generally, the issue is caused by that the size of the data sent to report server is larger then what the web.config file will allow. By default, the maxRequestLength parameter is set for 4 mb. In your scenario, since you are uploading the report to report manager, you need also to change below code in Report Manager directory web.config file(%Program Files%\Microsoft SQL Server\ MSRS12.MSSQLSERVER\Reporting Services\ReportManager\web.config).

    <httpRuntime executionTimeout= "9000" maxRequestLength="2097151" />

    Before changing values, please make a backup of the web.config file. Then restart the reporting services service.

    If you have any question, please feel free to ask.
