前言

一般涉及修改财务凭证，或者其它凭证，不应直接更新数据库，而是使用系统提供的function module,或者BAPI，或者使用BDC。

一、

示例：pandas 是基于NumPy 的一种工具，该工具是为了解决数据分析任务而创建的。

二、使用步骤

1.FI_DOCUMENT_CHANGE

注意一般调用结束后还应该考虑commit work，和rollback work。

如果手动SE37测试发现在S/4没更新ACDOCA可能是就是这个原因导致的，具体可查看解释：

2713775 - FI_DOCUMENT_CHANGE is not updating ACDOCA - SAP for Me

代码如下（示例）：

*&---------------------------------------------------------------------*
*& Report ZTEST
*&---------------------------------------------------------------------*
*& Test program: Update FI document
*&---------------------------------------------------------------------*

*       Commit the changescall function 'BAPI_TRANSACTION_COMMIT'exportingwait = 'X'.endif.endif.
endif.

2.FI_ITEMS_MASS_CHANGE

这个FM里面其实是在使用BDC进行修改，

代码如下（示例）：

CALL FUNCTION 'FI_ITEMS_MASS_CHANGE'
EXPORTING
S_BSEG = wa_bseg
IMPORTING
ERRTAB = it_errtab[]
TABLES
IT_BUZTAB = it_buztab
IT_FLDTAB = it_fldtab
EXCEPTIONS
BDC_ERRORS = 1
OTHERS = 2
