I want to add a many-to-1 relationship between facilities and e-mails, so that I can set e-mails regarding a facility.
I tried to copy an existing many-to-1 like the relationship between accounts and e-mails, but the system wont let me set a Parental relationship.
Can someone tell me what names, and settings, I should set for the new Many-to-1. Normally I wouldn't ask such a silly question, but I have damaged CRM in the past by incorrectly settings up many-to-1's.
