AGR_USERS table record deletion impact

Hello all,

I need to purge some role to user associations. I'd like to do this deleting records that reflect this association at Oracle level in AGR_USERS table, within PL/SQL procedure. This procedure :

- calculate all role that are allocated to the same user several times.

- delete corresponding records in AGR_USERS table

I'd like to know :

- potential side effects of such a solution and if there's no one :

     - SAP system behavior in this case : does it implicitly delete these associations in su01 ? PFCG ?

     - Is it practicable online ?

Here's my config :

SAP ECC 6.0 kernel 700

Oracle 11.2.0.3.0

HP-UX B.11.23 U ia64

Thanks in advance

Emmanuel
