前台T-CODE：FB01
调用BAPI : BAPI_ACC_DOCUMENT_POST
- BAPI 行项目字段增强
T-CODE SE11 创建结构，该结构包含了要增强的字段和行项目(该字段必须有)
Paste_Image.png
然后 T-CODE SE19 开始进行增强实施（有字段是BAPI里面没有需要新增时，需要建结构存储。例：反记账编码，记账码...）
在 SE19 创建典型 BADI 输入 ACC_DOCUMENT 步骤如图
Paste_Image.png
进入以下界面点击增加，然后选会计凭证：

点击保存后进入以下界面点击新建

然后
Paste_Image.png
选中刚创建的
Paste_Image.png
然后回到 T-CODE SE19 界面，编辑实施界面输入刚才创建的实施名称，点更改

进去后在实施累中双击第一个方法，将如下代码复制进去。

传值要加前导0
DATA: wa_extension TYPE bapiparex,
ext_value(960) TYPE c, wa_accit TYPE accit,
l_ref TYPE REF TO data.
FIELD-SYMBOLS: TYPE ANY,```
``` TYPE ANY.
SORT c_extension2 BY structure.
LOOP AT c_extension2 INTO wa_extension.
AT NEW structure.
CREATE DATA l_ref TYPE (wa_extension-structure).
ASSIGN l_ref->* TO .
ENDAT.
CONCATENATE wa_extension-valuepart1 wa_extension-valuepart2
wa_extension-valuepart3 wa_extension-valuepart4
INTO ext_value.
MOVE ext_value TO .
ASSIGN COMPONENT 'POSNR' OF STRUCTURE TO .
READ TABLE c_accit WITH KEY posnr =
INTO wa_accit.
IF sy-subrc IS INITIAL.
MOVE-CORRESPONDING TO wa_accit.
MODIFY c_accit FROM wa_accit INDEX sy-tabix.
ENDIF.
ENDLOOP. ```
到此增强部分就做完了，剩下的只要在 BAPI_ACC_DOCUMENT_POST 中的扩展表将参考结构和
参考结构建的工作区(里面存放了要增强的字段的数据)分别赋给即可。

* 备注
1、根据情况对应的去传值
2、在调用该 BAPI 之前，可以调用相应的检查函数看看错误 BAPI_ACC_DOCUMENT_CHECK。
3、每有计算税的行项目，就需要额外产生一行税的项目，在批导循环的时候记得判断并计算相应
的税。
4、当特别总账为 W、X、Y、Z、U、V 时，该 BAPI 无效，此时可以用函数 POSTING_INTERFACE_DOCUMENT
