PROCESS_HEADER not fired in BADI ME_PROCESS_PO_CUST

Question

Dear experts,
I face the problem, that the method PROCESS_HEADER of BADI ME_PROCESS_PO_CUST is not fired, when I am changing po header text. My requirement is to set a customer po header field, whenever a po header text is existent.
Does anybody know, if this is the standard behaviour and how I can work around it?
Thanxs

Hi Aparna,
actually I tried this, too.
In the methods Check and Post (which both are fired normally) I coded my requirements, but in this methods I faced the problem that I was not able to save my programatic header field changes. (Even with the trick to cast the IM_HEADER to CL_PO_HEADER_HANDLE_MM to allow changes of internal attributes, used in method set_data(), any changes of po header fields were not saved.) But maybe I am wrong with my implementation? You may have a look:
  DATA: lv_val_id TYPE thead-tdid.
  DATA: lv_val_name TYPE thead-tdname.
  DATA: lv_val_object TYPE thead-tdobject.
  DATA: p_mepo_header TYPE MEPOHEADER.
  DATA: it_tline TYPE TABLE OF TLINE.
  DATA: lv_cl_po_header_handle_mm TYPE REF TO CL_PO_HEADER_HANDLE_MM.
check existents of po header text
  lv_val_id = 'F09'.
  p_mepo_header = im_header->get_Data( ).
  lv_val_name = p_mepo_header-ebeln.
  lv_val_object = 'EKKO'.
  CALL FUNCTION 'READ_TEXT'
  EXPORTING
      client = sy-mandt
      id = lv_val_id
      language = sy-langu
      name = lv_val_name
      object = lv_val_object
    TABLES
      lines = it_tline
    EXCEPTIONS
      ID = 1
      LANGUAGE = 2
      NAME = 3
      NOT_FOUND = 4
      OBJECT = 5
      REFERENCE_CHECK = 6
      WRONG_ACCESS_TO_ARCHIVE = 7.
any text there, then update customer po header field
  IF sy-subrc = 0.
    p_mepo_header-zzfield = 'X'.
  else.
    p_mepo_header-zzfield = ' '.
  endif.
QD
  lv_cl_po_header_handle_mm ?= im_header.
  lv_cl_po_header_handle_mm->my_cust_firewall_on = 'X'.
  im_header->set_Data( p_mepo_header ).
  im_header->set_changed( ).
po is still same as before and field zzfield was not updated.
