I am going through and adding fields to featureclasses when I came across this error. We have 2 licenses (Standard/Basic) and on the basic level I get the error and on the Standard level it runs just fine. I am wondering if there is any way around this without upgrading or having to switch licenses just to run my script. I am also worried that by running this with the standard license that I will not be able to ever run it with the basic. I understand the obvious answer is to upgrade but I thought I would see what some other options are.
