Work orders and bookings have independent lifecycles, but a booking's state influences the work order's status (Microsoft). For example, changing the booking status to Traveling automatically changes the work order system status to In Progress (Microsoft). Additionally, the creation of a booking automatically changes the work order system status to Scheduled (Microsoft). If there are multiple bookings for a single work order and one booking is in progress, the related work order status gets updated (Microsoft). The related work order system status changes to Completed when all related bookings are completed or canceled (Microsoft). However, regardless of status settings, the booking status has no impact on the status of Resource Requirements (Microsoft). By default, the system sets work orders to completed when the associated booking gets completed, but you can create or edit a booking status and set the Status completes work order toggle accordingly to change this default logic (Microsoft). For instance, a custom booking status with the Status completes work order toggle set to Off allows completing the booking to return the work order to an earlier stage for follow-up instead of marking it Completed (Microsoft). When you deactivate a parent record, such as a work order in Field Service, the system doesn't automatically deactivate its child records (Microsoft).
In contrast, "Track Field Service Jobs for Efficient Management" states that setting the status of a service appointment doesn’t change the status of the work order line item or work order that it’s associated with (Salesforce). This means that in this environment, the appointment and the work order operate as separate status tracks. For example, the status Dispatched means the service resource is traveling to the work site (Salesforce). The status Cannot Complete means the service resource was unable to finish the work (Salesforce). The status Closed means all work and associated activity is complete (Salesforce).
Similarly, "Activity and Work Order Status Update Work Flow" documents that when an activity is in 'Pending' or 'Started' status in Oracle Fusion Field Service, the work order operation is in 'Ready' status, and there's no change in the initial work order status (Oracle). This indicates that starting field activity does not, by default, alter the initial work order status in this system. When an activity is completed in Oracle Fusion Field Service, the corresponding operation status is changed to 'Completed'; when all the operations associated with the work order are completed, the status of the work order changes to 'Completed' (Oracle).
These differences matter for dispatch planning. If your platform does not automatically propagate status changes, you must manually update the work order to reflect field progress. If your platform does propagate changes, you must verify that the automatic updates align with your actual field conditions. For instance, if a technician is traveling but has not yet begun work, an automatic "In Progress" status might mislead office staff into thinking work is underway.
Editorial recommendation: Verify your specific platform’s status propagation rules before relying on automatic updates. If your system does not link appointment and work order statuses, add a manual step to your dispatch checklist to update the work order when the appointment status changes. If your system does link them, test the propagation with a sample job to ensure it matches your workflow expectations. Do not add, remove, or edit the option set values for Work Order System Status; instead, consider creating meaningful Work Order Substatus records (Microsoft).
