Downtime applies to a vehicle that is not currently usable, generally because it is in the shop. It starts automatically when the work order status changes to OPEN. There are two types of downtime: shop and user. They are calculated using two different calendars. Downtime is managed through work orders.

• Shop downtime refers to the shop-related time that an equipment unit is down. It begins to accumulate when a work order is opened for the unit because the unit is in the shop being repaired or waiting for parts. It ends when work on all work orders opened for the unit is finished (the work order status changes to WORK FINISHED). Shop downtime is calculated based on the location calendar of the shop for which the work order is open.

• User downtime is the department-related time that an equipment unit is down. It begins to accumulate when the unit becomes inoperable, a work order is opened for the unit, or the unit has been made available for PM. It ends when all work orders for the unit are closed (the work order status changes to CLOSED). It is calculated based on the department calendar of the department to which the equipment unit is permanently assigned.

You can use the checkboxes on the right side of the Basic Info tab of the Data -> Shop Activity -> Work Order Center screen to start or stop downtime on an open work order. Downtime details are listed on the Summary Cost Info tab of the Data -> Shop Activity -> Work Order Center screen, and you can change the number of hours of downtime if you have the proper authorization. If user downtime hours are changed, the total hours of user downtime on JOB_MAIN are also updated.

Downtime is tracked on work orders, but concurrent work orders for the same equipment unit do not track downtime as overlapping. When downtime hours are calculated for a work order, any overlapping work orders receive an adjustment of downtime hours for the overlapping amount.

Although delays do not affect downtime by default, certain delays can affect shop downtime. If there is a check (ü) in the Stop shop downtime when work order is in delay for this reason field on the Data -> Shop Activity -> Setup -> Work Delay Codes screen, shop downtime is stopped while the work delay is in effect. Shop downtime restarts automatically once the delay has been lifted unless there is a check (ü) in the No downtime will accumulate for open work orders with this status field on the Basic Info tab of the Data -> Shop Activity -> Setup -> Service Statuses screen. Downtime restarts only if both the service status and the current delay (if any) specify that it should.

The dates and times that downtime began and ended are recorded in the JOB_DOWNTIME table. The equipment unit's accumulation of user and shop downtime on all work orders is recorded in the EQ_COST_DATA table. The equipment unit's accumulation of user and shop downtime on specific work orders is recorded in the JOB_MAIN and JOB-DOWNTIME tables.

• You can view this data in reports. To run a report, you can use the Queries/Reports -> Query/Report Generator screen, Web Modules Reporting, or any other reporting tool sold separately (such as Microsoft Access) that can attach to the database.
