Extended_xml_handling using client proxy

Question

Hi,
I´m using an client proxy in WAS 6.20 to call XI 3.0. I need to control one of the fields using the "extended_xml_handling" parameter. But how do i set the FIELD field in the control tab?
I use this code but i´m unsure how to field the ls_ctrl-field. Do anyone have an example?
  DATA: request  TYPE zskssend1.
  DATA: response TYPE zsksmt_string.
  DATA: ls_ctrl  TYPE prxctrl.
  ls_ctrl-field = 'ZSKSSEND1-SEND-TEMPORARYID'.
  ls_ctrl-value = sai_ctrl_nil.
  APPEND ls_ctrl TO request-controller.
  TRY.
      wk_ref_prox->extended_xml_handling = 'X'.
      CALL METHOD wk_ref_prox->execute_synchronous
        EXPORTING
          controller = l_controller
          output     = request
        IMPORTING
          input      = response.

I hope you have read this document.

You could also implement a workaround. Just pass some special character set e.g. $$## to all the blank fields in proxy response. You may then receive the data in XI and put some condition there to remove it.
