PL/SQL: ORA-22806: not an object or REF when Using Record in Package

Question

Oracle Database 11g Enterprise Edition Release 11.1.0.7.0
I have declared a record type in my package
create or replace
PACKAGE MYPKG AS
  TYPE MYREC IS RECORD (VAL1 varchar2(20), val2 date);
  PROCEDURE display_error (pSQLERRM number);
  PROCEDURE P_LOAD_DATA (pStartDate Date, pEndDate Date);
  FUNCTION  F_EPI(refno1 in NUMBER,  refno2 in NUMBER) return MYREC;
END MYPKG;
--In My Package Body
FUNCTION  F_EPI(refno1 in NUMBER,  refno2 in NUMBER) return MYREC is
        F_param MYREC;
        BEGIN
        select myvarchar2, mydate into MYREC from MYTable
          where myrefno1 = refno1
          and myrefno2 = refno2
        Exception
          when others then
          display_error(SQLERRM);
          RETURN F_param;
        END F_EPI ;
  PROCEDURE P_LOAD_DATA (pStartDate Date, pEndDate Date) IS
insert into atable(myvarchar, mydate)
select F_EPI(refno1,refno2).val1,F_EPI(refno1,refno2).val2 from tab2;
END P_LOAD_DATA;
I get errors
Error(187,7): PL/SQL: SQL Statement ignored
Error(225,7): PLS-00382: expression is of wrong type
Error(225,7): PL/SQL: ORA-22806: not an object or REF
When I compile the package.
When I try to call the function from SQL I get an Invalid datatype error.

Hi,
Before posting any query/plsql blocks, please ensure that you have written it clean and complete with less syntax errors. ( at least general syntax errors, you can avoid). Then somebody can have an interest to check your logical error.
About your posting, refer below solution step-by-step. It may help you, about what you are looking for? By the way, you must be knowing, what you are going to to do with. I haven't concentrated about your requirement; as it was not missing in your posting.
drop table test;
create table test(myvarchar varchar2(20), mydate date);
create or replace
    package mypkg as
      type myrec is record (val1 varchar2(20), val2 date);
      --procedure display_error (psqlerrm in number); -- if you are passing sqlerrm, then parameter needs to be string type
   procedure display_error (psqlerrm in varchar2);
      procedure p_load_data (pstartdate in date, penddate in date);
      function  f_epi(refno1 in number,  refno2 in number) return myrec;
   end mypkg;
Package created.
--in my package body
create or replace 
package body mypkg as -- added
procedure display_error (psqlerrm in varchar2) -- if you are declared a proc/func in spec, it needs to define in pkg body
is
begin
     null; -- you should know, what to do here
  dbms_output.put_line('Err -'||sqlerrm);
end display_error;
function  f_epi(refno1 in number,refno2 in number)
return myrec
is
f_param myrec;
begin
   -- select myvarchar2, mydate into MYREC from mytable
  --  where myrefno1 = refno1
  --  and myrefno2 = refno2;
    select ename, hiredate into f_param from emp -- added demo logic by using emp
    where empno = refno1
     and  mgr  = refno2;
    return f_param;  -- added
exception
   when others then
     raise; -- if you are using OTHERS then, just raise it
   display_error(sqlerrm);  
   --return f_param; -- what is this?
end f_epi;
procedure p_load_data (pstartdate in date, penddate in date) -- you must be knowing the use of 2 params ???
is
    v_rec myrec; -- added
begin -- Added
   --insert into atable(myvarchar, mydate)
  -- select f_epi(refno1,refno2).val1,f_epi(refno1,refno2).val1 from tab2;
   -- demo logic added with static params to call f_epi
   v_rec:= f_epi(7499,7698);
   insert into test values v_rec;
    --null; 
end p_load_data;
end mypkg;
Package body created.
SQL> exec mypkg.p_load_data(null,null);
PL/SQL procedure successfully completed.
