Each layer in a hosted feature layer contains an attribute table that stores the data for the layer. Each table contains rows (features) and columns (fields). How you interact with the attribute table of a hosted feature layer depends on your role in the organization and the layer's configuration. Most people can view the layers and use them in their own maps and apps, but only the layer owner or an administrator can manage attribute fields.
Nonowners who are not administrators
Anyone who is not the layer owner or is not an administrator in the organization can only interact with the attribute table's contents. If the hosted feature layer has been shared with you, you can do the following with the attribute table's contents:
- View the table's contents, related records and photos, and statistics. See Show tables for more information.
- If the layer owner has enabled editing, you can update the contents of the attribute table. If the layer owner has enabled attachments, you can attach related photos or other files to specific features. See the Work with attribute data section of Item details.
- If the layer owner has configured descriptions for the fields, you can see those descriptions in the layer's item page. Open the attribute table from the hosted feature layer's item page and hover over the field name to see the field description.
Owners and administrators
If you own the layer or you are an administrator of your organization, you can view and edit data in the attribute table, plus you can perform the following field management operations from the Data tab of the layer's item page:
- Add fields to or delete fields from the attribute table.
- Calculate field values.
- Add a unique constraint to a field.
- Define a list or range of values for fields.
- Describe each field.
- Set a display name.
Members of shared update groups can also perform some of these operations.
