修改合同号的bapi

这个例子是在合同号中新增项目号：

1、先要读取该合同号的信息用一个BAPI 

BAPI_CONTRACT_GETDETAIL

2、调用修改合同号的BAPI。

代码如下：

REPORT  ztest_class.

                   lt_item_condition  TYPE TABLE OF bapimeoutcondition,

             ls_item_conditionc TYPE bapimeoutcondition.

      lt_cond_validityc TYPE TABLE OF bapimeoutvalidity,

      ls_returnt TYPE bapiret2.
