Read-only column in Person

Hello everyone,

I want to modify the EmployeeType column in the Person so that when a new identity is created, this field is read-only and can only be changed through a template.

I updated the OnLoaded script by adding "Base.Columns("EmployeeType").CanEdit = False", but this only works when I open an existing identity. It doesn't work for a new one.

To explain better, I want the EmployeeType field to be read-only, just like the ImportSource field.

Does anyone have any suggestions?

Thanks,
Elena
