## Fields

### FSL__IsFillInCandidate__c

-   **Type**: boolean
-   **Properties**: Create, Defaulted on create, Filter, Group, Sort, Update
-   **Description**: Determines if this work order line item is considered as a candidate when filling in a schedule with the Fill-In Schedule feature. If a service appointment’s parent record is a work order line item, this field must also be set to true for the appointment to be a candidate. Alternatively, you can create a custom checkbox field through the Field Service Settings page, instead of using this field, to evaluate whether this appointment is considered as a candidate. The custom checkbox field includes formula fields.

-   **Default value**: `true`

### FSL__VisitingHours__c

-   **Type**: reference
-   **Properties**: Create, Filter, Group, Nillable, Sort, Update
-   **Description**: The visiting hours that define when service appointments associated with the work order line item can be scheduled. Visiting hours are enforced only if the Visiting Hours work rule is part of the scheduling policy.
