We are announcing the ability to Preserve actual booking End Time when completion is recorded later in Dynamics 365 Field Service. This feature will reach public preview on November 22, 2026.
How does this affect me?This feature allows Field Service administrators to choose whether completion by the booked resource automatically changes the booking End Time. Admins complete bookings later can preserve the existing or explicitly supplied work end, helping booking duration and downstream time and cost records remain aligned with when the work occurred.
Use the organization-level
Set End Time on booked resource completion setting in Field Service settings to control the automatic
End Time update.
- With the setting set to Yes, which is the default, current behavior is preserved. When the booked resource completes a booking without supplying End Time, Field Service sets End Time to the completion time and recalculates Duration.
- With the setting set to No, Field Service preserves End Time and Duration when the booked resource completes the booking unless the completion request explicitly supplies a different End Time.
- Completion by another user or an integration continues to preserve End Time for either setting value.
- When the setting is No and the booked resource completes the booking, Field Service uses the retained or supplied End Time as the effective Completed booking timestamp. This keeps timestamp-derived booking journals and automatic time entries aligned with the recorded work end. Dataverse audit fields continue to show when the completion was submitted.
The setting applies to future completion transitions and does not rewrite historical bookings. It does not change the booking-status lifecycle, invoice generation, or the existing Work Order Completed On calculation, which continues to use the latest eligible booking End Time.
