Policy - function_schema is not exp/imp properly

Question

Hi,
I have a schema that contains a policy as follows:
BEGIN
SYS.DBMS_RLS.ADD_POLICY (
object_schema => 'DYAHAV'
,object_name => 'TBL_BASE'
,policy_name => MY_VPD_PREDICATE'
,function_schema =>NULL
,policy_function => 'MY_VPD_PREDICATE'
,statement_types => 'SELECT,INSERT,UPDATE,DELETE'
,policy_type => dbms_rls.dynamic
,long_predicate => FALSE
,update_check => FALSE
,static_policy => FALSE
,enable => TRUE );
END;
After export and import to other schema, the object_schema is updated correctly
but the function_schema is still DYAHAV.
I really don't know if it's a feature or a bug...
How can I avoid it?
Thanks

try this, but replace the string 'SCHEMA_REQUIRED' with the functional schema name you require!
set serveroutput on
declare
  /* Replace the following string with whatever schema name is required for the functional schema */
  l_Schema_name varchar2(30) := 'SCHEMA_REQUIRED';
begin
  begin
    sys.dbms_rls.drop_policy(policy_name => 'MY_VPD_PREDICATE'
                          ,object_name => 'TBL_BASE');
    dbms_output.put_line('Policy, MY_VPD_PREDICATE, dropped');
    exception
      when others then
        dbms_output.put_line('Policy does not exist');
  end;
  sys.dbms_rls.add_policy (object_schema    => 'DYAHAV'
                          ,object_name      => 'TBL_BASE'
                          ,policy_name      => 'MY_VPD_PREDICATE'
                          ,function_schema  => l_Schema_name
                          ,policy_function  => 'MY_VPD_PREDICATE'
                          ,statement_types  => 'SELECT,INSERT,UPDATE,DELETE'
                          ,policy_type      => dbms_rls.dynamic
                          ,long_predicate   => false
                          ,update_check     => false
                          ,static_policy    => false
                          ,enable           => true );
  dbms_output.put_line('Policy, MY_VPD_PREDICATE, created');
  exception
    when others then
      dbms_output.put_line('Error ' || sqlerrm);
end;
