How to add an attribute in a Featurelayer

How can I add a new attribute in a Featurelayer. I know how to update existing features, but I want to add a new attribute to an existing Feature.

Hi P Herk‌,

Assuming that your Feature Layer is hosted in ArcGIS Online, these are the steps to follow:

in ArcGIS Online go to the item page of your hosted feature layer
go to the Data tab and select the layer you want to modify
click Fields to see the existing fields and their properties
here you will also find the Add button to add a field
after adding the field you can optionally create a list of values (domain) to limit the input to the new field

HTH,

Hello P Herk,

Since it's not clear whether you are wanting this workflow for use in ArcGIS Online or ArcGIS Pro, I will outline the process within Pro as well.

I hope this helps also!
