Specify the session timeout value in minutes for custom external extensions that have their own xxxHomeView.zul. The N4 setting FRMZK003 determines the number of minutes before session timeout that a user gets a timeout warning. Any changes to the setting will take effect the next time users log in.
Default: 20 (minutes)
Minimum: 1
Maximum: 720
N4 does not consider the <session-timeout> value in the web.xml file. You have to set the session timeout value for extensions with this setting.
