Hello Ramesh,
You need to activate SICF as per post steps guide of personas 3.0 and also follow certain steps to activate it.
Run -
Transaction /n/persos/admin_ui to check if its installed or not.
We have installed and configured Personas 2 and 3.0 both versions. Let me know if you required any further input.
See below screen -
Regards,
Amit Lal
