Hi Scott and All,
I got the DBA to grant execute to the workspace userid BHRS and run the 2 policies I have for the VPD as BHRS.
     begin
     dbms_rls.add_policy (
     object_schema => 'BHRS',
     object_name => 'MR_REQUEST',
     policy_name => 'USER_SU_POLICY',
     function_schema => 'BHRS',
     policy_function => 'GET_SU_USER_ID',
     statement_types => 'SELECT, UPDATE',
     update_check => TRUE
     end;
But, when I went to select * from MR_REQUEST
I got ORA-28112: failed to execute policy function
So I reduced my function down to returning null
     create or replace function GET_SU_USER_ID
     return varchar2
     as
     l_retstr varchar2(2000);
     l_count integer:=0;
     begin
     l_retstr := null;
     return l_retstr;
     end;
Researched a bit and found could look in the USER_DUMP file but the DBA here says the DB doesn't have one because we use the XDB ???
How can I check the policy errors or debug this problem?
Thanks Bill
