Hello,
We are using ArcMap 10.3.1 (Yes, extremely outdated) and I have run into an issue when attempting to add a new field to a particular Feature Class.
Typically it is quite easy. I right click the Feature Class I want to edit in the Catalog and select the "Properties" option. Then I open up the "Fields" tab. Find an empty row and type in the name of the new field.
However several of the Feature Class's that I need to add fields to do not have any more empty rows. Since the Feature Class is define in a MS SQL Database I could add the field/column with SQL, but I am worried that that ArcMap might preform some other logic when creating a field I don't know about.
I have attached screen shots that demonstrate what I am talking about.
Thanks for your help,
Daniel
