How to find Kernal Badi for standard transactions?

Hello Everyone.

I am new to kernal badi concept. By finding few posts in SCN, I have learnt what exactly the Enhancement Spot (Kernal Badi).

Usually for classic badi, We will find out the badi's using CL_EXITHANDLER.

Ex: ME_PROCESS_PO_CUST for ME21N

In the same way how we will find out Enhancement Spots for standard Transactions??

Is there any other procedure?

Please help me!

Thanks,
