BAPI_REQUISITION_CREATE
创建了服务类的采购申请里面有一个参数（REQUISITION_SERVICES）,
BAPI_REQUISITION_CHANGE 和
BAPI_PR_CHANGE但是这二个BPAI里都没有专门的参数存入服务类的数据；
还有一个奇怪的现象，创建申请的有二个BAPI修改的也有二个；可是BAPI_REQUISITION_CREATE 和BAPI_REQUISITION_CHANGE 从名字上看这二个应该是一起的一个创建一个修改，
可是这二个BAPI里的参数几乎都不一样；
而 BAPI_PR_CREATE 和 BAPI_PR_CHANGE这二个BAPI里面参数却都是一样的，很奇怪；很显然我如果用BAPI_PR_CREATE创建的申请可以用BAPI_PR_CHANGE来改（但这个BAPI却不能创建服务类申请，因为没有相关的参数），可是我用BAPI_REQUISITION_CREATE创建的申请却不能用BAPI_REQUISITION_CHANGE
来改。
