Problem:

How to adjust the idle timeout session when users are logged onto Sage 300 Web Screens.

Resolution:

Sage 300 Web screens, has an additional value in web.config file located in <program files>\online\web.
1. Open Web.config, search for "SessionState timeout"
2. By default value is set to 20 minutes, change to increase to allow longer idle time.

For older versions than 2020 refer as below:

Modify the web config file and insert the below string just prior to the Framework runtime section, adjust the hihlighted to suit your needs.

<!--Session (if exists) will be released from the pool based on this timeout (in minutes) (inactivity).-->
    <sessionState timeout="5" />
