### Required Permissions

All users assigned to a role with User Management permissions can view this feature.Only users who are assigned a role with User Management permissions can edit data or customize settings.

The ability to edit and customize select fields may also depend on which version of PULSE you are using (DC Unlimited or MyDC). See the topics below to learn more:

- [Know Your VAS PULSE Version](docId\:jwUSXGpK0Q1fVyl3QyB1n)
- [Edit Dairy User Permissions](docId\:dgKiJJMfdmpDvWGygh_P2)
- [Manage Dairy Roles](docId\:tklz3_ROmKlipE8l-rFi6)

The **Item Definitions** page displays detailed information on all items configured for your dairy. MyDCdairies include standard, predefined items commonly used throughout the industry. DC Unlimiteddairies may also have custom or dairy-specific items. PULSE items capture specific animal data points, including numbers, dates, animal status, and milk production details that are critical to managing your herd. These data points are the foundational components of VAS data analysis and daily management tools, including reports, worklists, and PULSE widgets. You can find this feature under the [DairyComp/MyDC menu](docId\:T93yU--9puoivxMGYpo5g) > [Settings](docId\:T93yU--9puoivxMGYpo5g) option on the Task Lists tab.

With the correct permissions, DC Unlimited subscribers can view additional item details and edit their settings. MyDC subscribers can only edit item descriptions.
