How many affect when testcase is edit.

Dear,

I have many Testcase and I used testcase in testcase below.

The testcase(scenario tc) that has many testcases is many case in project.

If some testcase is edit, testcase(scenario tc) is no problem because edited testcase will be applie all testcase(scenario tc).

But I can't know what testcase(scenario tc) is affect by editing.

How can I that information.

I try to use the 'Find' function, but the 'Find' is only searched script.

Please let me know.

Thanks
