Use an event when case work takes place at a scheduled date and time.
Review the workspace timezone and both dates, especially for overnight or multi-day work. Confirm that the end follows the start.
Open the event, select Edit, adjust its schedule, and save with Update Activity. Calendar views may also let authorized users drag an event to another date. Review the resulting schedule after moving it.
Events do not use the Service field in the activity form. After the event, create a linked update to document results and record time and expenses through the appropriate workflow.
