I'd like to know how people are handling limitations of user name lengths. We are looking at revising out email address naming conventions and would like to keep the user name account the same as the local part of the email address. Ideally, I'd like to have the email address follow an RFC convention (Rod.Snyder@) Is there a way to map the email local part to the SAP User Account? Also, what are the char limits on SAP users accounts? I'm being told it is 12 and that seems a little low.
