Define how workspace items are identified by selecting fields from the Item Details tab to include in the workspace descriptor.
A descriptor is a label made up of key item fields, such as the item name, number, or other attributes. Descriptors appear in places such as the Item Details page header, links, lists, and search results, helping users quickly identify items throughout the site.
From the main menu, go to Administrator > Workspace Manager.
Select the workspace whose descriptor you want to update.
The workspace settings page opens.
In the left-side panel, click Descriptor.
Using the drop-down lists, select up to four fields to include in the descriptor, in the order you want them to appear.
Click Save.

Choose stable fields: Descriptor fields are not dynamic. Use fields with constant values. If you include fields that change frequently, those changes will not automatically update in the descriptor.
Avoid restricted fields: Avoid using fields from restricted sections of the Item Details tab. These fields will not show or hide in the descriptor based on user permissions. Even if a user cannot access that section, the value will still display in the descriptor.
Protect sensitive information: Avoid using fields with sensitive or confidential data. Item descriptors are visible across your site in links, picklists, when adding items to tabs, and other areas, even if users don't have access to the item's full details.
