My database is a carry-over from ACCPAC.

I have always just used the SYS User since I am the only one in accounting.

Recently, I have been having many problems when I am signed in as SYS. I created a new User and all those problems are gone.

I would like to delete the SYS User but I can't. I can't replace it either.

I really want to get rid of this User. It is causing bizarre problems.

Why do I need to keep it?
