最近一個開發，在eban里追加了字段，
調用bapi賦值總是賦不進去
后來發現找的結構名稱不對，
是：BAPI_TE_REQUISITION_ITEM 不是BAPI_TE_MEREQITEM
實例代碼如下：
REPORT zlm_pr_create.
DATA: pr_item LIKE TABLE OF bapiebanc WITH HEADER LINE,
pr_account LIKE TABLE OF bapiebkn WITH HEADER LINE,
pr_item_id LIKE TABLE OF bapiebantx WITH HEADER LINE,
pr_return LIKE TABLE OF bapireturn WITH HEADER LINE.
DATA: l_return LIKE pr_return.
DATA: extensionin TYPE TABLE OF bapiparex WITH HEADER LINE .
DATA: lw_itm TYPE bapi_te_requisition_item.
DATA: matnr TYPE matnr.
DATA: pr_no TYPE bapiebanc-preq_no.
START-OF-SELECTION.
CALL FUNCTION 'CONVERSION_EXIT_ALPHA_INPUT'
EXPORTING
input = '500000004'
IMPORTING
output = matnr.
pr_item-doc_type = 'NB'. "憑證類型
pr_item-preq_item = '00010'. "項目
pr_item-material = matnr. "商品代碼
pr_item-quantity = 1. "數量
pr_item-deliv_date = '20130819'. "交貨日期
pr_item-plant = 'BA01'. "工廠
pr_item-pur_group = 'B02'. "采購組
pr_item-c_amt_bapi = 100. "評估價格
APPEND pr_item.
CLEAR pr_item.
lw_itm-csid = '991'.
lw_itm-preq_item = '00010'.
extensionin-structure = 'BAPI_TE_REQUISITION_ITEM'.
extensionin-valuepart1 = lw_itm.
APPEND extensionin.
CALL FUNCTION 'BAPI_REQUISITION_CREATE'
IMPORTING
number = pr_no
TABLES
requisition_items = pr_item
requisition_account_assignment = pr_account
requisition_item_text = pr_item_id
return = pr_return
extensionin = extensionin[].
LOOP AT pr_return WHERE type = 'E' OR type = 'A'.
ENDLOOP.
FREE pr_item.
FREE pr_account.
FREE pr_item_id.
FREE pr_return.
