If you need a different view of the data represented by a hosted feature layer—for example, you want to apply different editor settings, apply different styles or filters, define which features or fields are available, or share the data to different groups than the hosted feature layer—create a hosted feature layer view of that hosted feature layer.
When you create a feature layer view, a new hosted feature layer item is added to Content. This new layer is a view of the data in the hosted feature layer, which means updates made to the data appear in the hosted feature layer and all of its hosted feature layer views. However, since the view is a separate layer, you can change properties and settings on this item separately from the hosted feature layer from which it is created. For example, you can allow members of a specific group to edit the hosted feature layer but share a read-only feature layer view with the rest of your organization.
Only the owner of a hosted feature layer can create a hosted feature layer view from the original layer. This is different than copying a layer, which can be done by non-owners and even public users.
Create a hosted feature layer view
Follow these steps to create a hosted feature layer view from a hosted feature layer:
- Sign in to your organization.
You must have privileges to create content, and you must be the owner of the hosted feature layer from which you want to create the view.
- Open Content > My Content and open the item page for the hosted feature layer you want to use as a source for the view.
The layer must be a hosted feature layer, not a feature layer added from the web or a feature collection.
In addition, you cannot create hosted feature layer views from the hosted feature layers used to archive ArcGIS GeoEvent Server data or those created when you run GeoAnalytics Tools.
- Click Create View on the Overview tab of the item's page.
- Type a unique title for the hosted feature layer view.
- Type tag terms separated by commas.
Tags are words or short phrases that describe your item and help people find your item when searching. Federal land is considered one tag, while Federal,land is considered two tags.
- Type a summary that describes the use and content of the view.
- Choose the folder where the hosted feature layer view will be stored and click OK.
The hosted feature layer view's item page appears when the view is created. Now you can apply the setting changes you want to the hosted feature layer view.
Hosted feature layer view settings
Settings for hosted feature layer views fall into three categories, as described in the following sections.
Settings inherited from the hosted feature layer that cannot be independently configured on the views
Hosted feature layer views inherit the following settings from the hosted feature layers from which you create them. When any of these settings change on a hosted feature layer, the settings also change on all its views; you cannot independently change these settings on the hosted feature layer view.
- The ability to store attachments on individual layers
- The ability to track who creates and edits data
Settings inherited from the hosted feature layer that you can change on the view
Hosted feature layer views inherit the following from the hosted feature layer from which you create them. If you prefer a different configuration for the feature layer view, you can change the view's configuration without affecting the hosted feature layer.
Settings that can be made independently on views and the hosted feature layers from which they are created
Hosted feature layer views do not inherit the following from the hosted feature layer from which you create them. Set these separately on the view.
Considerations when creating hosted feature layer views
Keep the following in mind when you create hosted feature layer views:
- You can only make schema changes, such as adding or removing a field, to the primary hosted feature layer. Any existing dependent views inherit these schema changes from the primary hosted feature layer.
- If you need to refresh the data, overwrite the hosted feature layer from which the view was created. The data updates appear in the view.
You cannot overwrite the hosted feature layer from ArcGIS Pro or ArcMap if you add layers to the map, delete layers from the map, or reorder the layers in the map before overwriting. If you need to add, delete, or reorder layers before overwriting the hosted feature layer, you must first delete all dependent views.
- Hosted feature layer views and the hosted feature layers from which they are created must have the same owner. To reassign ownership, the administrator must change ownership on the hosted feature layer; ownership of the layers' views also change.
- You can create a maximum of 20 views from the same hosted feature layer.
- Synchronization is not supported on hosted feature layer views at this time.
- You can only create hosted feature layer views from hosted feature layers that store their data in a relational ArcGIS Data Store.
