函数使用六：ABAP4_CALL_TRANSACTION

此函数是在程序中调用一个事物代码，跳转或者执行事物代码的程序。

参数说明：

Import

TCODE                            执行的事物代码

SKIP_SCREEN                  跳转事务代码的初始屏幕，只在跳转时用

MODE_VAL                      BDC时使用，对应 默认A:前台，显示屏幕    E:遇到错误停止并显示    N:后台模式

UPDATE_VAL                   BDC时使用，对应 默认A：异步   S:同步     L:本地模式，LOCAL UPDATE

Export

SUBRC                            SY-SUBRC     返回值

Table

USING_TAB                      DBC DATA TABLE   如果调用BDC事务，BDC DATA的内容通过此表传值

SPAGPA_TAB                    Parameter   一般做跳转的参数设置 SET PARAMETER ID

MESS_TAB                       Message Table BDC 返回消息内表
