删除外向交货单是没有直接以delete结尾的bapi的，是使用的change：BAPI_OUTB_DELIVERY_CHANGE
已经过账的交货单应该是先冲销，再删除，这里暂时不写了。
仅考虑没过帐的交货单。
一般而言，做删除操作都是打删除标记，
但是交货单（未过账）的是直接物理删除（前台和bapi同样是物理删除）。

Change outbound delivery (VL02)
To delete the outbound delivery pass VBRP-VGBEL (Document number of the reference document) to the function module & set dlv_del flag 'X'. To check the functionality of the function module go to ME23N transaction, pass the purchase order number. After successfully execution of function module it will delete the delivery from ME23N transaction.
*---declaration of BAPI
DATA: wa_hdata LIKE bapiobdlvhdrchg,
wa_hcont LIKE bapiobdlvhdrctrlchg,
d_delivy LIKE bapiobdlvhdrchg-deliv_numb,
it_bapiret2 LIKE bapiret2 OCCURS 0 WITH HEADER LINE.
Loop at it_vbrp.
CLEAR: wa_hdata, wa_hcont, d_delivy, it_bapiret2.
wa_hdata-deliv_numb = it_vbrp-vgbel.
wa_hcont-deliv_numb = it_vbrp-vgbel.
wa_hcont-dlv_del = c_x.
d_delivy = it_vbrp-vgbel.
