BAPI_PO_CREATE1 Service Positions and Conditions with reference to P. Req.

Question

Hello together,
i have the following problem. I used the BAPI BAPI_PO_CREATE1 to create Purchase Orders with reference to a purchase requsition. I have 2 different types of purchase requsitions. One with normal items and one with services.
So for both the creation of the purchase order works but if i add Conditions on Serivce Item Level to the purchase requsition they are not transfered to the purchase order.
To eliminate misunderstandings in a purchase order there are 3 diffent typs of conditions possible. First on header Level of the purchase order which can easly be filled with BAPI. The second on item level of the purchase order with can also easily be filled with BAPI and the last on service level which i doesn't found in BAPI. May be someone has an idea how to fill these conditions.
Here is my code:
  header-doc_date = wa_eban-erdat.
  value = 10.
Set COMP_CODE
  select single bwkey from t001w into lv_bwkey
                where werks = wa_eban-werks.
  select single bukrs from t001k into header-comp_code
                where bwkey = lv_bwkey.
  header-doc_type = wa_eban-bsart.
  header-vendor = wa_eban-flief.
  header-created_by = sy-uname.
  header-purch_org = wa_eban-ekorg.
  header-pur_group = wa_eban-ekgrp.
  header-langu = sy-langu.
  header-status = 'B'.
  header-indx = header-indx + 1.
  append header.
  headerx-doc_type = 'X'.
  headerx-comp_code = 'X'.
  headerx-vendor = 'X'.
  headerx-purch_org = 'X'.
  headerx-created_by = 'X'.
  headerx-pur_group = 'X'.
  headerx-created_by = 'X'.
  headerx-langu = 'X'.
  headerx-status = 'X'.
  headerx-indx = header-indx.
  append headerx.
