Example: Field mapping
The Category breakdown maps the Category field on the incident table to the Incident.Category breakdown source, which references the Choices[sys_choice_list] table.
In the first image, you see the Category breakdown with the Incident.Category breakdown source. This breakdown has a breakdown mapping to the Category field on the incident table.

Finally, you see the Category field of some records on the Incident table. This field is mapped to the Category breakdown. The field values match the Label fields of the records of the Choice [sys_choice_list] table that the Incident.Category breakdown source filters for.
