How to recreate SAP* user master record in a client

Hi..

Due to some urgency, we have deleted SAP* from database(Oracle) using command-

delete from SAPPRD.USR02 where BNAME='SAP*' and MANDT='500';

Now after deleting SAP*, i need to login with password while parameter "login/no_automatic_user_sapstar=1" is set.

Because user master record does not exist for client 500, I am unable to login with user SAP*.

I also tried to recreate user SAP* using SU01 but it result to ABAP dump with message--

"The ABAP/4 Open SQL array insert results in duplicate database records."
