Within a table, it is used as a foreign key for multiple fields (e.g. ObserverID, RecorderID, CheckerID). I have successfully added relationships (with in the the MS Access 'Relationship' view), where I have table aliases to do the multiple relationships per table: *tblUser.UserID -> 1 to many -> tblResight.ObserverID *tblUser_1.UserID -> 1 to many -> tblResight.CheckerID After creating about 25 relationships with enforcement of referential integrity, when I try to add an additional one, I get
