Deletes an existing work order event by id. This removes a single scheduled/requested occurrence of a work order (for example, one technician's specific maintenance visit), not the parent work order definition itself. 
The `userId` parameter identifies who performed the deletion, for audit trail purposes.

---
### Parameters
**workOrderEventId** `Integer`: Id of work order event to delete<br />
**userId** `Integer`:Id of the user executing the function<br />

---
### Returns
**# of records modified** `Integer`<br />
**msg** `String` None if success<br />

---
### Example
```python
# Delete a work order event that was created in error
workOrderEventId = 8842
userId = system.kanoa.security.getIDPUserId({'userName': 'SYSTEM'})
recordsModified, message = system.kanoa.cmms.deleteWorkOrderEvent(workOrderEventId, userId)
print recordsModified, message
```
