Purpose of table ADR6?

Hello Experts,

Can anyone please tell me what is the use of table ADR6? When/how an entry is inserted in this table? What is it used for?

Why I am asking for this is because I want to test ERMS scenario.BASIS team has given me an e-mail id for testing which is not there in this table. I was just thinking whether it has to be there for ERMS scenario or this table is used for some other purpose.

Regards,

Rohit
