Always generation of new spool request when using message type WNAK

Question

Hey!
I have one question regarding the printout of message type WNAK.
In SAP standard the print program RWBNASTV and entry routine ENTRY_ABR_NATRAB is used.
Now I want to ensure that at every printout generates a new spool request.
Problem is that when a user prints a purchase order and after that a Sett. Crdt Agrmt (WNAK) the second printout is attached to the previous spool.
How can I ensure that there is always a new spool file generated without copying the print program and the corresponding function modules before OPEN_FORM?
In the print conditions I only know the function "Immediately print" but that is no help if the printout is attached to the purchase order which was printed before.
Is there no flag which escpecially ensures that for this message type should be always be generated a new spool request?!?!
I hope you know something else.
With kind regards.
Mark

Answer 1

I alreadey copied the print program and the function modules but I am still looking for another solution because I think that is not the best solution for the problem.
I changed following in include LWNPNFO0 (copied to LYWNPNFO0):
--- Konvertierung der Kommunikationsdaten:                         --
  MOVE-CORRESPONDING pi_nast TO lvs_snast.
  MOVE sy-repid              TO lvf_program.
  CALL FUNCTION 'CONVERT_COMM_TYPE_DATA'
    EXPORTING
      pi_comm_type              = lvs_comm_type
      pi_comm_values            = lvs_comm_values
      pi_screen                 = pi_screen
pi_newid                  = 'X'
      pi_country                = pi_tocountry
      pi_repid                  = lvf_program
      pi_snast                  = lvs_snast
    IMPORTING
      pe_itcpo                  = lvs_itcpo
      pe_device                 = lvf_device
      pe_mail_recipient         = lvs_recipient
      pe_mail_sender            = lvs_sender
    EXCEPTIONS
      comm_type_not_supported   = 1
      recipient_creation_failed = 2
      sender_creation_failed    = 3
      OTHERS                    = 4.
  IF sy-subrc <> 0.
    MOVE sy-subrc TO po_retcode.
    PERFORM error_message_arrang_append_sy TABLES ptx_error_messages
                                                USING  pi_kona
                                                       dummy_vake.
  ENDIF.
  CHECK po_retcode = 0.
*--- Öffnen des Formulars:
  CALL FUNCTION 'OPEN_FORM'
    EXPORTING
      archive_index  = toa_dara
      archive_params = arc_params
      device         = lvf_device
      dialog         = ' '
      form           = pi_formular
      language       = pi_nast-spras
      OPTIONS        = lvs_itcpo
      mail_sender    = lvs_sender
      mail_recipient = lvs_recipient
    EXCEPTIONS
      canceled       = 1
      device         = 2
      form           = 3
      OPTIONS        = 4
      unclosed       = 5
      mail_options   = 6
      archive_error  = 7
      OTHERS         = 8.
  IF sy-subrc NE 0.
