SAP ABAP模块BAPI函数开发及应用 创建BAPI程序的步骤

创建BAPI程序的步骤
1.定义BAPI Structure (Structure不能在BAPI中重复使用，因为一旦BAPI被释放，其Structure被冻结）（T-CODE：SE11）
2.创建FUNCTION MODULE（T-CODE：SE37）

每个BAPI必须有自己的Function Group，Function Group属性必须为RFC

3.创建Business Object(T-CODE：SWO1)

4.使用BAPI WIZARD创建API Method (T-CODE:SWO1:Utilities--API methods--methods)

这样BAPI可以被外部程序调用

5.Function Module符合BOR Method

4.释放BAPI Function Module,释放Business Object Type,（先释放对象类型在释放对象类型下的组件）

释放BAPI作为BOR的一种Method

Path：CODE：SWO1àEditàchange release statusàObject typeàTo modeled、、、、

创建BAPI注意事项

1. 要注意 Function Module 要释放了之后, 在SWO1中才可以把 method设为 reaslse. 到se37中, Function Module ---> release ---> release.
2. 添加方法: swo1中, 把鼠标选中在Method上,然后点Create,输入Function的名字, Function加入到了Method中之后,双击这个method,进入method的属性,然后在"ABAP"选项卡中选择API. 然后释放Object和组件.
3. 改变 Object 和 component的状态: edit ----> change release status --->
4. 然后 "产生" 就可以了.
5. SOW1中创建对象的时候,必须要用package才可以,不然对象是不可传送的.
