SQL & PL/SQL

hi all,

i am calling a packaged procedure which has collection type as in parameter which resides in remote database by using synonyms.for which i am creating a synonym in my current schema.

Below package in remote database:
CREATE OR REPLACE PACKAGE BODY test_hlr
AS
PROCEDURE raj_test (
pi_username IN VARCHAR2,
pi_serial_no IN arr_numb, --user defined collection type
po_error_code OUT NUMBER
)
AS
BEGIN
FOR i IN pi_serial_no.FIRST .. pi_serial_no.LAST
LOOP
INSERT INTO hlr_raj
(user_name, serial_no
)
VALUES (pi_username, pi_serial_no(i)
);
END LOOP;
END;
END;



i am creating synonym for package in my current database and calling that synonym package as shown below

create synonym ram_test for ram_test@dblink

CREATE OR REPLACE PACKAGE BODY test_bnr
AS

PROCEDURE ram_test (
pi_username1 IN VARCHAR2,
pi_serial_no1 IN arr_numb, --user defined collection type
po_error_code OUT NUMBER
)
AS

BEGIN
test_hlr.raj_test (pi_username => pi_username1,
pi_serial_no => pi_serial_no1,
po_error_code => po_error_code
);
END;
END;

while compiling above package am getting below error
PLS-00306: wrong number or types of arguments in call to 'RAJ_TEST


if i remove collection type and use primitive data types then am not getting any error.

please give any suggestions, regarding the same.

Sri Ram.
