When you click the Delete button on the Job Notes form, you will get a message warning you that you are about to delete the selected contact log. You have the option at this point to cancel or go ahead and delete the selected record. If you confirm that you want to delete the selected record, VisionCore will delete it and there will be No way of retrieving that contact log again.
The Delete button can be password protected so that other users can't delete any of the job contact log records. You can assign a password to the delete buttons in the Security form.
