Alessandro,
Thanks for your reply.
Yes, I have gone through this document and believe that, it helps in looking up for the manager of a user using F4 button (lookup), correct me if required. However, what I want is, as soon as a user id is selected, the manager field should be filled automatically from the data source: HR or LDAP if it is maintained there.
I believe this is the default behavior of the application.
Please advise.
Regards,
Faisal
