+The tracing data points in the error message can help you identify what went wrong. The violation types include:

-  - The locked booking is outside of resource working hours.
-  - Promised time window is invalid.
-  - Travel time is invalid.

   - The locked booking conflicts with a [scheduled break time](/dynamics365/field-service/set-up-bookable-resources#add-work-hours).
