change like this .. dup will get avoided
if required do message handling
  CALL FUNCTION 'ME_EKPO_SINGLE_READ'
    EXPORTING
      pi_ebeln                  = is_mseg-ebeln
      pi_ebelp                  = is_mseg-ebelp
*   PI_BYPASSING_BUFFER       =
*   PI_REFRESH_BUFFER         =
   IMPORTING
     po_ekpo                   = ls_ekpo
EXCEPTIONS
   NO_RECORDS_FOUND          = 1
   OTHERS                    = 2
  IF sy-subrc = 0.
    CHECK ls_ekpo-elikz = 'X'.
    CONCATENATE 'Delivery Already Completed for' 'Line item:' is_mseg-ebelp '-' 'Material:' is_mseg-matnr INTO message_var.
    MESSAGE e002(sy) WITH message_var.
  ENDIF.
