No data Found when executing select within a function

Question

Hi
I have a select statement based on the USER_ROLE_PRIVS view for a specific granted_role and user, If I execute the statement in SQL/Plus I obtain the required result, however if I put the same select in a function and excute the function signed on as the same user I get ora-00100 no data found. I have granted execute to public on the function. Is there a grant I have missed
Any Help would be Great

  3  v_return number := 0;
  4  v_granted_role user_role_privs.granted_role%type;
  5  BEGIN
  6  Select granted_role
  7  into v_granted_role
  8  from USER_ROLE_PRIVS
  9  where Granted_Role = 'CONNECT'
10  and username = user;
11  v_return := 1;
12  RETURN v_return;
13  EXCEPTION
14  when no_data_found then
15  v_return := 0;
16  RETURN v_return;
17  when others then
18  v_return:= 9;
19  RETURN v_return;
20* END;

PL/SQL procedure successfully completed.Your supplied code works fine for me - Executing in owner schema. Then only authid current_user is missing in your code
