Creating New User ID's in SAP

Hello All,

We are planning to implement a new user ID naming convention for our SAP users. Is there any way to automatically copy all the user ID specific/related settings like data entry screen variants (for example: users move around columns in a data entry screen), report layouts, SAP query user authorizations and any other settings into a new user ID?

I am given to understand that this can be done only manually. I unfortunately do not have SAP Security / Basis background to look in the right places and would appreciate any pointers.

Thanks!
