PL/SQL function returning refcursor produces error in BI Publisher data set when a parameter is used.

Test case to reproduce error:

Create a PL/SQL function that returns a ref cursor;

  create or replace function fn_refcursor(p_number in number)
  return sys_refcursor is
  type t_refcursor is ref cursor;
  l_refcursor t_refcursor;
  open l_refcursor for
  select dummy
  from dual
  where 1 = p_number;
  return l_refcursor;
  end fn_refcursor;

Test the function in a BIP data set as Standard SQL, successfully viewed the data;

  select fn_refcursor(p_number => 1) from dual

Replace the literal with a valid parameter in the BIP function call, error viewing the data;
