How to get the own schema data while calling the other schema's Procedure

Question

Hello Experts,
I'm Sanjit, new to OTN forum.
I'm using Oracle 10g 10.1.0.2.0 database. Another user Sush has created one procedure proc_1 like
create or replace procedure proc_1
as
v_total number;
begin
select sum(amt) into v_total from trans_master where dot
between add_months(sysdate,-3) and sysdate;
dbms_output.put_line('last three months total transactions is: '||v_total);
end proc_1;
He has the Trans_master table and having 280 records and I have the same Trans_master table with 430 records
inserted in last 3 months. He has granted execute privileges on the procedure Proc_1 to me. When I call the procedure
I cannot call it directly like my own schema procedures: Exec Proc1;
I am calling like : Exec Sush.Proc1 to get the result. My issue is: when the procedure is called,
it is accessing the data from the Sush schema Trans_master table with 280 records total, but I want
the procedure to get the total amount of transaction of 430 records from my own Trans_master table.
Please resolve my issue which would be a great help. And is there any way to call the procedure of other schema
by not attaching the owner name of the object with it?
Thanks
Sanjit

Pleast take a look at "Definer's rights and invoker's rights" in the following article:
http://docs.oracle.com/cd/E11882_01/timesten.112/e21639/accesscntl.htm#BABDDCHC
I guess you need to define a stored procedure with "invoker's rights".
If this is what you are looking for will have to define it in the stored procedure that you are going to call.
The syntax is as follows:
create or replace procedure <yourprocedure> authid current_user ...
...or (the following is the default, you don't have to use the "authid definer" keywords):
create or replace procedure <yourprocedure> authid definer ...
...hm
