Configurate self-reference field to add [Account Name] to [Accounts] form.
On the following parent - child relationship, registering child company from parent company of [Accounts] leads entering parent record on the self-reference field.
Also, self-reference field cannot be deleted because it's connected to parent company record on mapping settings.
This behavior takes a lot of time and trouble to delete values entered automatically, when entering [Accounts] other than parent company to self-reference field.
It would be user-friendly if user can select mapping works or not without being mapping automatically.
