Authorization object P_ADMIN doesn't exist

Hello SAP security experts!

I'm still having problems with configuring authorizations for personas 3.0.

I asked for a solution in SCN personas place but didn't get any answer.

Here is the description of the problem.

Configuring Authorizations and Roles for Personas 3.0

I have added /PERSONAS/ADMIN_ROLE to my user and created authorization profile for this role.

However I'm not able to add authorization objects (P_ADMIN, P_EDIT, P_RUNTIME), cause they don't exist in my system (I've checked in SU21).

I also noticed that such objects exits in the table TOBJ.

So I have two questions:

• How can it be that authorization objects exist in TOBJ but can't be added to the authorization profile?
• Why I don't have this objects in my system (what should I do in order to get them)?

Thanks in advance.
