'BAPI_GOODSMVT_CREATE可以实现物料凭证创建和部分冲销
全部冲销可以使用BAPI_GOODSMVT_CANCEL
CALL FUNCTION 'BAPI_GOODSMVT_CREATE'
EXPORTING
GOODSMVT_HEADER = GOODSMVT_HEADER
GOODSMVT_CODE = GOODSMVT_CODE
IMPORTING
MATERIALDOCUMENT = MATERIALDOCUMENT
MATDOCUMENTYEAR = MATDOCUMENTYEAR
TABLES
GOODSMVT_ITEM = GOODSMVT_ITEM[]
RETURN = RETURN[].
抬头部分给值：
GOODSMVT_HEADER-PSTNG_DATE = SY-DATUM.
GOODSMVT_HEADER-DOC_DATE = SY-DATUM.
GOODSMVT_HEADER-PR_UNAME = SY-UNAME.
GOODSMVT_HEADER-REF_DOC_NO = S_PBLNR-low.
GOODSMVT_HEADER-HEADER_TXT = 'Packing List Post'.
GOODSMVT_CODE = '04'.
行项目部分给值（根据移动类型有差异）：
loop at gt_itab WHERE WERKS = GT_ITAB1-WERKS.
GOODSMVT_ITEM-MATERIAL = gt_itab-matnr.
GOODSMVT_ITEM-PLANT = gt_itab-werks.
GOODSMVT_ITEM-STGE_LOC = gt_itab-lgort.
GOODSMVT_ITEM-MOVE_TYPE = '311'.
GOODSMVT_ITEM-ENTRY_QNT = gt_itab-menge.
GOODSMVT_ITEM-ENTRY_UOM = gt_itab-meins.
GOODSMVT_ITEM-ITEM_TEXT = gt_itab-MBLNR.
GOODSMVT_ITEM-MOVE_PLANT = gt_itab-werks.
if gt_itab-lgort+0(1) = 'B'.
GOODSMVT_ITEM-MOVE_STLOC = 'B902'.
elseif gt_itab-lgort+0(1) = 'C'.
GOODSMVT_ITEM-MOVE_STLOC = 'C902'.
ENDIF.
append GOODSMVT_ITEM.
endloop.
冲销时与正常创建凭证一样，只是BAPI2017_GM_ITEM_CREATE-XSTOB = 'X'. "冲销标志 移动类型为正向，比如261发料，做262的冲销，移动类型仍给261，不需要修改，此处打叉即可
MBST冲销整个凭证：

EXPORTING
materialdocument = gt_up-MBLNR
matdocumentyear = gt_up-MJAHR

GOODSMVT_HEADRET = GOODSMVT_HEADRET
