ABAP 通过字段找表程序

2.获取数据保存在哪个数据表的方法：

1.前台对指定栏位 使用F1帮助找表，
2.st05 跟踪业务操作过程，检索需要的数据表，（此方法找表很高效）
3.对于文本字段找表，可以找到前台维护处，->维护长文本->表头->表名，
4.F1某些时候找表找到的是结构，可以试着通过结构找include 组件，有找到表的可能，还可以通过相关视图去查找，（找到视图基本就能找到表）
4.通过相关标准report / query去查找；
5.找到对应程序，或者相应操作，使用调试+设置watchpoint 查找，
6.通过结构 或者检查表找，
7.通过data element ->domain ->值表，
