Defining unavailability
Unavailability means that for whatever reason, no production can be planned at certain dates in a calendar. When defining a calender, you need to consider several types of unavailability and how they are going to influence the planning.
To define unavailability for a calendar use these sessions:
Recurring unavailability
For recurring unavailability, such as national holidays, define the recurrence in the Recurrences (tcccp0143m000) session. Add that recurrence to the applicable calendar code and availability type in the Calendar Exceptions (tcccp0144m000) session, and clear the Available check box for the unavailable days.
With calendar recurrences you define recurring exceptions in a calendar, and set a time schedule for daily, weekly, monthly, or yearly unavailable time in one action.
Unavailable days for all calendars using a specific calendar code
To define occasional unavailability, such as a department trip, use the Non-working Days (tcccp0119m000) session. What you define here applies to all calendars that are using this calendar code.Unavailable days for a specific calendar
To define unavailability for a single day, complete the following steps:
- Start the Calendar Working Hours (tcccp0120m000) session.
- Find the applicable calendar, and clear the Available check box for a intervals on the relevant date.
If you defined unavailable dates in the Non-working Days (tcccp0119m000) or the Calendar Exceptions (tcccp0144m000) session, in the Calendar Working Hours (tcccp0120m000) session, click .
