Declaring a variable to be of a type of a table's column in another schema

Question

Hi,
Can anyone please explain why is the below procedure not working, but the same is working when written in a declare begin block:
--exception:Compilation errors for PROCEDURE BOOK_STG.TEST
Error: PLS-00201: identifier 'BOOK.POLICY_METHOD' must be declared
CREATE OR REPLACE PROCEDURE test(out_test VARCHAR2) IS
test_it book.policy_method.policy_type%TYPE;
BEGIN
SELECT policy_type INTO test_it FROM book.policy_method WHERE rownum < 2;
out_test := test_it;
dbms_output.put_line(out_test);
END;
--below block is working:
declare
test book.policy_method.policy_type%TYPE;
BEGIN
SELECT policy_type INTO test FROM book.policy_method WHERE rownum < 2;
dbms_output.put_line(test);
END;

END;Check how the GRANT for the object BOOK.POLICY_METHOD is given for the current user. If it is through a ROLE then you cannot use it inside a SP. To use an OBJECT inside a SP you need Grant given directly.
