I have a view with 3 fields that can be automatically filled (default proc) when selecting one value from a view having all three values concatenated.This makes finding things a lot easier for the user. The field is only defined in the view and nothing is stored in the database….
A similar situation now exists in a table. There is currently no need for a view instead of this table, so an expression field could be the solution here. Expression fields in the SF however are by definition read-only.
So why not have the developer deside whether an expression field is read-only or not; most of us are wise enough to know what we're doing.
To show what I mean, see link below… I made an expression field editable using SQL on the SF database, and you;ll see what I want to achieve. Works fine according to me.
