Master field

From UG

Master field (a.k.a. "orange field") - field that follows "master field logic":

1) Orange fields (also marked with '**') are Common fields for Indiv CT and Master.

2) Master rules, meaning that If Indiv CT is assigned to Master then corresponding Common fields from Master will replace same fields in CT without warning

3) Also, following assigment of CT to a Master, Common fields become read only. Editable through Master only. Changes through Master to these fields will propagate into corresponding fields for each CT that is a part of this Master
