Enhancement for me53n through BADI

Question

Hi Experts,
                 I need to check the Open order and closed order item in ME53N t-Code(PR) through Quantity and quantity order filed. Now the problem is Order Quantity value is exceeds than quantity.if Quantity value is equal to Order Quanity the order should be closed. If Quantity value is lesser than order quantity the order should be in open state.
Thanks
Rajesh

Not quite sure what you actually want to do here.
Do you want to "modify" an existing BADI  or create a new one.
AFAIK there aren't any existing BADI's for ME53 so you'll have to create a new one --not too difficult so long as you follow the rules.
You will need some place also to call it from (a User / Screen exit / a user mod or whatever.)
Use code something like this.
*& Report  Z_BADI_TEST
REPORT  Z_BADI_TEST.
test call Badi from standard abap. (Only from rel 6.40 and above)
do the following
1) define the Badi  (SE18). For Abap call  test uncheck multiple use
                            and filter boxes
2) Implement the badi (SE19). Add any methods here in the implemntation
3) activate
4)  define the standard class exithandler to the abap. This class is the "Badi caller
5)  define an exit variable referring to your Badi Implementation interface
    this interface  will normally be something like ZIF_EX***************
    You will see this  in SE18/SE19.
6)  Instantiate your instance of the badi (method call get_instance)
7)  Now call any method(s) in the Badi.
    class cl_exithandler definition load.      "Declaration
    data exit type ref to zif_ex__jimbotest.        "Interface reference
    data yes type c.
    data: v_knvv type knvv.                         "Used in Fmod call in Badi methods
    start-of-selection.
    yes = ' '.
  selection-screen  begin of block b1.
  parameters: r1  radiobutton  group rad1,
              r2  radiobutton group rad1,
              r3  radiobutton group rad1.
  selection-screen end of block b1.
    parameters: p_kunnr type knvv-kunnr.
    select  single * into v_knvv
    from knvv
     where kunnr eq p_kunnr.
     export v_knvv to memory id 'CUST6A'.   "Save customer data for the function module
break-point 1.
    call method cl_exithandler=>get_instance      "Factory method call
            exporting                                                "Method
                exit_name           = 'Z_JIMBOTEST' "Name of your BADI
            changing instance = exit.
   if not exit is initial.
    if r1 = 'X'.
     call method exit->dispord     "Add-In call
        exporting kunnr = p_kunnr.
endif.
if r2 = 'X'.
call method exit->dispfakt.
endif.
if r3 = 'X'.
call method exit->dispmat.
endif.
endif.
Your badi will have different methods -- just check your quantities and if necessary close the order.
Ensure that when you call your Badi you have access to all the releveant data to close the order if required.
