The administrator at Cloud Kicks deleted a custom field but realized there is a business unit that still uses the field. What should an administrator take into consideration when undeleting the field?

When a custom field is undeleted, its previous references, including its presence in reports, are automatically restored; it generally does not need to be manually re-added to reports.

Upon undeletion, the custom field's associated field history tracking and data are typically restored along with the field.

To undelete a custom field, an administrator must access the 'Deleted Fields' section in Salesforce setup, which functions as a recycle bin for custom fields, and initiate the restore process from there.

Upon undeletion, the custom field is automatically restored to all page layouts where it was previously visible, negating the need for manual re-addition.
