The web service integration for Epic ROI respects the request execution timeout configured for the OnBase Application Server. To ensure the web service can retrieve large files without exceeding the timeout, you may need to increase the value for the executionTimeout setting on the Application Server. This setting is located in the httpRuntime element in Web.config. The executionTimeout value is specified in seconds.
If Epic is communicating with the Application Server through the OnBase Web Server, then the executionTimeout setting also needs to be increased in the Web.config file of the Web Server.
