Create goods issue in case of batch split with bapi_goodsmvt_create

hi ,

i'm trying to create a goods issue in case of batch split and i meet some problems and errors using the bapi 'BAPI_GOODSMVT_CREATE'

please i need more details about filling the items structure of bapi

    gt_goodsmvt_item-material             =  matnr.

    gt_goodsmvt_item-plant                =   werks.

    gt_goodsmvt_item-stge_loc             =  lgort.

    gt_goodsmvt_item-vendor               =  vendor.

    gt_goodsmvt_item-batch                =  charg.

    gt_goodsmvt_item-deliv_numb_to_search =  gv_delivery.

    gt_goodsmvt_item-deliv_item_to_search =  posnr.

    gt_goodsmvt_item-move_type            =  '261' .    "'101'

    gt_goodsmvt_item-entry_qnt            = 1 .    "'50'.

    gt_goodsmvt_item-entry_uom            = 'ST'.

    gt_goodsmvt_item-mvt_ind              = 'L'.

    gt_goodsmvt_item-ord_id            =  vgbel.

    gt_goodsmvt_item-ord_itno           = vgpos.

    gt_goodsmvt_item-no_more_gr           = 'X'.

is this filling is correct for the main item (0010) and also for the batch items (900001 , 900002) ??

and how to fill the batch of item 0010 ?? ( it's blank in the case of split batch )

many thanks
