## Fields

### FSL__HoursInUse__c

-   **Type**: double
-   **Properties**: Filter, Nillable, Sort
-   **Description**: The total number of hours of scheduled services occupied by the service resource. This is used by the Field Service dispatcher console to show how much resource capacity is used up and by the scheduler to prevent offering resources whose capacity is full. This field is updated when the scheduler runs and updates the `FSL__MinutesUsed__c` field. This is a calculated field.
-   **Formula**:

    ```nolang
    FSL__MinutesUsed__c / 60
    ```


### FSL__Last_Updated_Epoch__c

-   **Type**: double
-   **Properties**: Create, Filter, Nillable, Sort, Update
-   **Description**: The date and time, in Epoch format, that the Capacity object was last updated. The Capacity object is updated when a service is scheduled on a capacity-based resource. This field is used by the Field Service dispatcher console.

### FSL__MinutesUsed__c

-   **Type**: double
-   **Properties**: Create, Filter, Nillable, Sort, Update
-   **Description**: The total number of minutes of scheduled services occupies by the service resource. This is used by the Field Service dispatcher console to show how much resource capacity is used up and by the scheduler to prevent offering resources whose capacity is full.

### FSL__Work_Items_Allocated__c

-   **Type**: double
-   **Properties**: Create, Filter, Nillable, Sort, Update
-   **Description**: The number of scheduled service appointments that fill the capacity. This is used by the Field Service dispatcher console to show how much resource capacity is used up.
