I know that but I don't want the solution that way.
It should work like if I am logged-on to SAP at 10:00 AM, for e.g. & kept session ideal for let's say 30 min. then my id should logged-off from my PC automatically. Similar feature is available in SAP R/3 but it's not here in B1.
So I want to achieve this by some development, if possible.
