This screen is used to create/edit/view Service Ratio Calendars.
These are used to determine the dates and times that a Service Ratio applies.

The top part of the screen contains the calendar details.
The bottom part contains the events in the calendar.

The fields are as follows:

Calendar Events

Calendar Events determine when a Service Ratio applies.
Wherever there is:

• an event, the Service Ratio will be applied
• no event, the Service Ratio will be ignored

To add, change, or delete events, double click on a cell to edit it.
If the cell is empty, a new event will be created.
