SAP ABAP 调用其他程序如 ALV 报表程序的源码

1：可以一个创建接口，方法见博客
https://blog.csdn.net/qq_41757790/article/details/126301085?spm=1001.2014.3001.5501

2：定义一个与报表输出表字段相同的结构体及内表。
若报表输入框为多项选择，输入函数可以选择表形式。
PS：传入参数的类型尽量不要过于复杂，可能会不便于其他系统的开发人员调用。

3：示例：
创建一个接口读取报表程序查询的值返回给外部系统（通过这个方法，传递与报表同样的数据不用再复写一遍逻辑）。

报表程序界面如下：

方法 1 ——通过 submit 的形式调用 ALV 报表程序，源码如下：
