abap 创建会计凭证的bapi

可以使用BAPI_ACC_DOCUMENT_POST来创建会计凭证。以下是一个示例ABAP代码：

DATA: ls_header TYPE bapiache09,
      lt_items TYPE TABLE OF bapiacgl09,
      ls_items LIKE LINE OF lt_items,
      lt_return TYPE TABLE OF bapiret2,
      ls_return TYPE bapiret2.

* 填充会计凭证头信息
ls_header.companycode = '1000'.
ls_header.documentdate = sy-datum.
ls_header.fiscalyrvariant = 'V1'.
ls_header.documenttype = 'SA'.
ls_header.postingdate = sy-datum.

* 填充会计凭证行项目信息
CLEAR ls_items.
ls_items.accountgl = '100000'.
ls_items.amount = 100.
ls_items.taxcode = 'V1'.
APPEND ls_items TO lt_items.

CLEAR ls_items.
ls_items.accountgl = '200000'.
ls_items.amount = -100.
ls_items.taxcode = 'V1'.
APPEND ls_items TO lt_items.

* 调用BAPI创建会计凭证
CALL FUNCTION 'BAPI_ACC_DOCUMENT_POST'
  EXPORTING
    documentheader = ls_header
  TABLES
    accountgl = lt_items
    return = lt_return.

* 检查返回信息
LOOP AT lt_return INTO ls_return.
  IF ls_return-type = 'E' OR ls_return-type = 'A'.
    WRITE: / ls_return-message.
  ENDIF.
ENDLOOP.

在实际使用中，需要根据具体的业务需求填充会计凭证头和行项目信息。同时，需要注意会计科目、税码等信息的正确性和合法性。
