About Fiori Session Timeout

[Former Member]

I have a question about the Fiori timeout.
I would like to know if there are any differences in my understanding.

The software I use is SAP S/4HANA 2020 01FP.

I think there are mainly two ways to set Fiori timeouts.
"①Server-Driven Sign-Out"
"②UI-Driven Sign-Out"
Since ② is not set, the timeout of ① is applied.
However, the SESSION_TIMEOUT_STOP_DATA_REFRESH parameter is not set.

When I run Tr-CD:SICF_SESSIONS in SAPGUI and check the parameters, they are set as follows.

login/create_sso2_ticket = 3
login/accept_sso2_ticket = 1
login/ticketcache_entries_max = 1000
login/ticketcache_off = 0
login/ticket_only_by_https = 1
icf/set_HTTPonly_flag_on_cookies = 0
icf/user_recheck = 1
http/security_session_timeout = 1800
http/security_context_cache_size = 2500
rdisp/plugin_auto_logout = 1800
rdisp/autothtime = 60

With the above settings, how long will it take for Fiori to time out ?
Also, please tell me how to calculate that time.

Personally, I recognize that the two parameters "http/security_session_timeout" and "rdisp/plugin_auto_logout" are related to the Fiori timeout time, and that the timeout is the sum of the values ​​of both parameters.
(Ex) Timeout in 30 minutes
①http/security_session_timeout = 1800
②rdisp/plugin_auto_logout = 1800
①+②=3600s (30min)

However, I do not understand the relation and behavior of http/security_session_timeout and rdisp/plugin_auto_logout.
I would appreciate it if you could explain it in detail.

Thank you in advance
