Canceling A Field Activity
You should cancel a field activity if it shouldn't be (or wasn't) done.
There are situations when a field activity may be canceled automatically by another process in the system, for example:
If a field activity is created by start/stop and the start/stop is canceled, the resulting field activity is also canceled
If a field activity is created by a severance event or cut event and the severance or cut event is canceled, the field activity is also canceled
The processes that attempt to cancel a field activity when a related record is canceled do not continue with the cancel under the following conditions:
The field activity is already linked to a field order (and is therefore considered dispatched to the field)
The field activity has been dispatched to an external system and the FA's intermediate status is one that does not allow auto-cancellation.
