Today i upload all report of my project and get error
Error : There was an Exception running the extension specified in the config file –> maximum request length exceeded.
The basic problem here, is that your posting an amount of data to a web app larger than it is configured to accept. Hence, it is throwing an error, and simply saying “no!”
It’s an easy fix though! You’ve got to tweak the web.config for the web app, which in the case of reporting server, is usually somewhere like this:
C:\Program Files\Microsoft SQL Server\MSRS10_50.SQLEXPRESS\Reporting Services\ReportServer
Find the web.config file for your reporting services instance, open it up, and track down the line that looks something like this
<httpRuntime executionTimeout = "9000" />
Now just add a max request length attribute in there to fix the problem, adjust your size as needed. This is 5meg.
<httpRuntime executionTimeout = "9000" maxRequestLength="500000" />
And now you’ll need to restart IIS. start->run->”iisreset”
