How to used BAPI_SALESORDER_CHANGE to add items

Question

Hi, I am trying to use the above bapi to add items to a sales order, but I can't get the qty to map across.  I had the same problem using the create bapi whcih I resolved by populating the schedule tables, but in change this just causes an "unhandled exception" to occur, so i can;t even step into the FM to see the problem.  Has anyone got any ideas.
s_header_inx-updateflag  = 'U'.
*   set item data
    s_items-itm_number     = s_stock-item_no.
    s_items-material       = s_stock-material_no.
    s_items-target_qty     = s_stock-quantity.
    s_items-target_qu      = s_stock-uom.
    s_items-ref_doc        = s_stock-agreement.
    s_items-ref_doc_it     = s_stock-agreement_item.
    s_items-batch          = s_stock-batch.
    s_items-plant          = s_stock-plant.
    s_items-store_loc      = s_stock-storage_location_no.
    append s_items to it_items.
*   set flag to add items (I)
    s_itemsx-updateflag    = insert.
    s_itemsx-itm_number    = s_items-itm_number.
    s_itemsx-material      = abap_true.
    s_itemsx-target_qty    = abap_true.
    s_itemsx-ref_doc       = abap_true.
    s_itemsx-ref_doc_it    = abap_true.
    s_itemsx-batch         = abap_true.
    s_itemsx-plant         = abap_true.
    s_itemsx-store_loc     = abap_true.
    append s_itemsx to it_itemsx.
    s_sched-itm_number    = s_items-itm_number.
    s_sched-sched_line    = '0001'.
    s_sched-REQ_DATE      = sy-datum + 30.
    s_sched-req_qty       = s_items-target_qty.
    append s_sched to it_sched.
*   set flag to add items (I)
*    s_schedx-updateflag    = 'I'
    s_schedx-itm_number    =  s_items-itm_number.
    s_schedx-sched_line    = '0001'.
    s_schedx-REQ_DATE      = 'X'.
    s_schedx-req_qty       = abap_true.
    append s_schedx to it_schedx.
* Now call the BAPI to add the items
  call function 'BAPI_SALESORDER_CHANGE'
    exporting
      salesdocument             = me->number
*   ORDER_HEADER_IN             =
    order_header_inx            = s_header_inx
    SIMULATION                  = ' '
*    BEHAVE_WHEN_ERROR           = 'P'
*   INT_NUMBER_ASSIGNMENT       = ' '
*   LOGIC_SWITCH                =
*   NO_STATUS_BUF_INIT          = ' '
   tables
    return                      = it_return
    order_item_in               = it_items
    order_item_inx              = it_itemsx
*   PARTNERS                    =
*   PARTNERCHANGES              =
*   PARTNERADDRESSES            =
*   ORDER_CFGS_REF              =
*   ORDER_CFGS_INST             =
*   ORDER_CFGS_PART_OF          =
*   ORDER_CFGS_VALUE            =
*   ORDER_CFGS_BLOB             =
*   ORDER_CFGS_VK               =
*   ORDER_CFGS_REFINST          =
    order_schedules_in          = it_sched
    order_schedules_inx         = it_schedx
*   ORDER_TEXT                  =
*   ORDER_KEYS                  =
*   CONDITIONS_IN               =
*   CONDITIONS_INX              =
*   EXTENSIONIN                 =

hi,
BAPI_SALESORDER_CHANGE didn't work for me either though i'm 100% sure the bapi works
See SAP note 366265 which tells you how to fill the structures but
you can use your program which you used to create the sales order to change the order and all you need to
do is change a few parameters
CALL FUNCTION 'BAPI_SALESORDER_CREATEFROMDAT2'
  EXPORTING
   SALESDOCUMENTIN               =  P_VBELN
    ORDER_HEADER_IN               = ORDER_HEADER_IN
    ORDER_HEADER_INX              = 'U'
(make sure your partners are blank, otherwise you'll get a duprec on VBPA)
-( PS , yes, i;m saying , see if BAPI_SALESORDER_CREATEFROMDAT2 works for you)
I hope this helps
