获取数据保存在哪个表

  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）
  5. 通过相关标准 report /query 去查找
  6. 找到对应程序，或者相应操作，使用调试 + 设置 watchpoint 查找
  7. 通过结构或者检查表找
  8. 通过 data element ->domain -> 值表
