本文介绍如何通过增强SAP BAPI功能来生成预制凭证。主要步骤包括设置凭证抬头状态值并填充凭证行项目的特定字段。此外，还提供了一个测试程序示例。

利用此BAPI生成预制凭证,首先要在如下用户出口做一个简单增强：

ACBAPI01 会计核算: 对 BAPI 界面的客户增强功能

对应的出口函数是：EXIT_SAPLACC4_001

相应的代码如下，核心内容是要让凭证抬头中的status_new值为2,即可生成预制凭证：

READ TABLE extension WITH KEY field1 = 'BAPI-PARK'.
IF sy-subrc = 0 .
MOVE 2 TO t_acchd-status_new. "to mark this is Park Document
ENDIF.

*此部分内容为BAPI标准参数中没有的字段，四个Field字段都是char250,如果字段太多，

可利用处理字符串拆分的方法进行

LOOP AT extension.
  READ TABLE t_accit WITH KEY posnr = extension-field1.
  IF sy-subrc = 0.
    t_accit-bschl = extension-field2.   "记帐码
    t_accit-rstgr = extension-field3.   "原因代码
    t_accit-umskz = extension-field4.   "特殊总帐标识

MODIFY t_accit INDEX sy-tabix.
ENDIF.

*在自己的程序或接口代码中调用BAPI，测试程序如下：
