写了一个接口，接口中使用CALL TRANSACTION的方法录的BDC，使用事务码“CO11N”进行报工。
在sap中运行测试是没有问题的，但是外部调用的时候，debug发现运行到CALL TRANSACTION语句的时候就会直接退出，有没有大神指导这是什么情况。
下面是代码：
FUNCTION z_rfc_002.
"----------------------------------------------------------------------
*""本地接口：
*" IMPORTING
*" VALUE(I_AUFNR) TYPE AUFNR
*" VALUE(I_VORNR) TYPE VORNR
*" VALUE(I_MENGE) TYPE MENGE_D
*" EXPORTING
*" VALUE(O_MESSAGE) TYPE CHAR40
*"----------------------------------------------------------------------
