We want to run the following report by BI Launchpad contiously on a screen (24x7):
The report consider about 30 datasources, which reloads every 100 minutes by a timer.
And there is a second which switches every 2 minutes the tabs.
But a few hours later, the report crashes. My guess for this cause was that the timeout was set too short.
1. login to the SAP System with the transaction "RZ11" -> *wprun* -> change the Value to 0, to end timeout. (https://blogs.sap.com/2015/02/13/how-to-set-timeout-setting-in-sap-business-intelligence/)
2. the CMC/BI Launchpad session timeout, modified the web.xml which is in the following path:
<BI 4.0 Install folder>\SAP BusinessObjects\Tomcat6\webapps\BOE\WEB-INF
But it still doesn´t work and i get the following error messge:
"The application has closed. This may have been caused by a loss of network connectiviy. Check your network connectivity and reload the application."
And in background "Unknown Error"
