I've recently inherited a slightly modified NAV 2013 installation, and I'm trying to do my first Cumulative Update on it. I was able to see that there are a handful of Tables, Codeunits, and Pages that show as modified in our system that have changes included in this CU. I assume my next step is to confirm whether the specific fields, functions, etc...have been changed within those objects.
This is where I'm a bit stuck, however. We have a developer license, but when I try to export the object to text it says I don't have permission. Also, when I try to open a codeunit in the designer it says I don't have permission. How else can I check these changes? Or is there some other step in between I'm missing?
