1.安装APIFOX，当然也可以使用在线版，无需下载
官网地址：https://apifox.com/
2.新建项目
3.为项目起一个名称，为相关开发测试人员授权
4.在根目录新增子目录
5.编辑开发/测试/生产环境的地址信息以及默认全局变量
6.将SAP提供的ABAPAPI地址配置进APIFOX,有关ABAP提供的服务地址，请参考文章：
1.ABAP 功能模块的 JSON 适配器
2.RESTFUL方式
7.与前一篇文章有所不同的是，本次在ABAP类中增加了更新模块，如图，请见代码：
8.在APIFOX新建好服务URL后，可以在根目录设置用户密码，这样后面子节点就可以继承根目录的用户配置
9.新建调用接口[本例是SAP函数：BAPI_ACC_DOCUMENT_POST]
9.1在BODY页签，现在json格式，输入测试的报文
