SAP ABAP数据库表字段checktable的实现原理

For project reasons I need to find all tables whose fields have used a given table say COMM_PRODUCT as check table.

How to efficiently find the exact one by yourself?

(1) Make the check table field selected, and press F1:

The DD08L seems to be the table I am looking for.

 

 

Double confirm in SE16:
