A web feature layer is any feature layer with a feature service as its data source. You can add a web feature layer or web map using a portal connection, a connection to ArcGIS Server, or directly by typing the service URL.
Feature templates published with a service appear in the Create Features pane. The author who published the layer or map as a web service determines if you can add, update, or delete features.
You can create and modify features and nonspatial data using the same editing tools you normally use to edit geodatabase feature layers. You can undo and redo individual edits and save or discard groups of edits for the current feature service.
You can't undo edits made to the default version of feature layers published by reference with version management enabled.
Editing a web feature layer, or those referencing data in an enterprise geodatabase, for the first time from a version of ArcGIS Pro that did not support undo and redo shows the following message.
Use a portal connection
Use a portal connection to add and edit a web feature layer or web map.
As with any service hosted on a website, the server URL for ArcGIS Server can vary and depends on how the server is configured. Your server site administrator should have this information.
The following steps outline a basic workflow for adding a new connection to ArcGIS Server using a URL. After you add the connection, you can add any of its shared feature services to a map for editing.
Note:
Once a server has been added to your project, you can view and
modify its connection properties in the Catalog pane.
To edit feature services, change the connection to a User connection.
On the Insert tab, in the Project group,
click the Connections drop-down menu .
Click New ArcGIS Server.
In the Server URL box, type the full URL for the server to which you want to connect.
For example, the following URL adds a connection to a sample server: https://sampleserver6.arcgisonline.com/ArcGIS/services
If required, type your user name and password.
If you want to save your user name and password information to avoid entering it each time you connect, choose the appropriate Save Username/Password setting.
Click OK.
A connection for ArcGIS Server is created and saved to your project. An item referencing this connection appears in the Catalog pane on the Project tab, in the Servers folder .
In the Catalog pane, expand Servers and expand the ArcGIS Server connection containing the feature service.
Add the web layer or web map using one of the following methods:
Drag the map service onto the map.
Right-click the map service and click Add To Current Map.
Tip:
To add individual sublayers, double-click to expand and browse the feature layers.
Use its service URL
If you know the service URL for a web layer or map, you can add it using its data path.
On the Map tab, in the Layer group, click the Add Data drop-down arrow.
Click Data From Path.
The Add Data From Path dialog box appears.
In the Path box, type the service URL.
For example, the following URL adds the Shelters feature layer from the NapervilleShelters feature service:
In some situations, you may need to download web feature layers to a geodatabase in your project home folder and edit features offline. When you work offline, you can synchronize your edits. When you no longer need to work offline, you can remove your local copy.
