参考指定WBS元素创建新的WBS，代码如下：

lv_desc TYPE bapi_bus2054_new-description,
lv_message TYPE string.

lv_str(960) TYPE c.

注意事项1：
调用BAPI：BAPI_BUS2054_CREATE_MULTI之前必须先调用BAPI：BAPI_BUS2054_CREATE_MULTI。
调用BAPI：BAPI_BUS2054_CREATE_MULTI执行成功之后，不能直接调用BAPI：BAPI_TRANSACTION_COMMIT，会导致DUMP，应该先调用BAPI：BAPI_PS_PRECOMMIT
注意事项2：
附加字段需要扩展系统标准结构BAPI_TE_WBS_ELEMENT中的嵌套结构：CI_PRPS
扩展结构CI_PRPS如下
