Greetings! I wish to add a custom field to Customer that is set once and only once upon transition to a Customer with a specific status value indicating the customer is Closed+Won (meaning, a valid new paying customer). I'm going to create a SuiteScript to create this string out of a string transformation of the customer name. My question: Is it possible to have a field that is set once, programmatically, and cannot be modified via the UI? What are all the Custom Entity Field settings I need to set? Store Value=true? Display Type: Hidden? Default Access Level: View? Anything else?
