このタスクについて

By defining a reference key, you can identify a field other than sys_id to use as the unique identifier for the reference field. The value of the reference key field, instead of the sys_id, is stored in the database for that reference field.

手順

1. Navigate to All > System Definition > Dictionary.
2. Open the field record (for example, resolved_by on the Incident table).
3. In the Reference key field, enter a field name on the referenced table (for example, email on the sys_user table).
   注:

   Always choose a field from the referenced table that is both required and unique.
4. Select Update.
