BAPI_GOODSMVT_CREATE - Still to be Delivered Quanity

Question

Hi All,
In the transaction Me23n, I can display my Purchase Order Number.
In the Header Data, Under the Status tab, I can see the Quantities as below:
Ordered: 400
Delivered: 300
Still to be delivered: 100
Now I run the BAPI_GOODSMVT_CREATE with the appropriate data and quatity eq 1. Now the data in the PO becomes:
Ordered: 400
Delivered: 301
Still to be delivered: 0
How come the 'Still to be delivered quantity' is becoming zero?
What I can do for this?
I am pasting the code I am using below:
  lw_goodsmvt_header-pr_uname = sy-uname.
  lw_goodsmvt_header-pstng_date = sy-datum.
  lw_goodsmvt_header-doc_date = sy-datum.
  lw_goodsmvt_header-ref_doc_no = <<Purchase Order Number>>
    lw_goodsmvt_item-po_item    = 40.
    lw_goodsmvt_item-move_type  = '101'.
    lw_goodsmvt_item-mvt_ind    = 'B'.
    lw_goodsmvt_item-plant      = <<Plant>>.
    lw_goodsmvt_item-material   = <<Matnr>>.
    lw_goodsmvt_item-entry_qnt  = 1.   
    lw_goodsmvt_item-stge_loc   = '0001'.
    lw_goodsmvt_item-move_stloc = '0001'.
    lw_goodsmvt_item-po_number  = <<Purchase Order Number>>.
    lw_goodsmvt_item-no_more_gr  = 'X'.
    APPEND lw_goodsmvt_item TO lt_goodsmvt_item.
Kindly Help

Hey Guys,
Thanks a lot, After a long time a problem of mine got solved so fast
Like we check the check box 'Item OK' in MIGO transaction, I will filling that parameter for the same purpose. Guess the BAPI take cares of that.. Am I right?
And there are other two questions which I am asking else where too but not getting any answer, so I will ask here too:
How to Update the 'Delivery Note' field in the Header of GR.
1) If I fill the lw_goodsmvt_header-ref_doc_no parameter of the BAPI with the PO Order Number, The Delivery Note field gets updated by the PO Number. But if I am filling anything else in the parameter like any alpha-numeric value, I am not able to post a GR. How can I achieve this.
2) Also I need to know how to update the 'Quantity in Delivery Note' using this BAPI?
