| To define unavailability |  |
| This topic describes the definition of temporary unavailability for resources in a calendar. Use one of the following 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 and availability type in the Calendar Recurrences (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 availability types To define occasional unavailability, such as a department trip, use the Calendar Non-Available Days (tcccp0119m000) session. What you define here applies to all availability types. Unavailable days for a specific availability type To define unavailability for a single day, complete the following steps: Start the Calendar Working Hours (tcccp0120m000) session. Find the applicable calendar and availability type, and clear the Available check box for a working hours type on the relevant date. Unavailable during a part of a day To indicate that part of a day is unavailable, use the Calendar Recurrences (tcccp0144m000) or the Calendar Working Hours (tcccp0120m000) session to specify the time intervals that are available. All other times are considered unavailable. You cannot directly specify an unavailable time interval. If you defined unavailable dates in the Calendar Non-Available Days (tcccp0119m000) or the Calendar Recurrences (tcccp0144m000) session, in the Calendar Working Hours (tcccp0120m000) session, click Update Calendar. Note Unavailability always applies to entire days. If the Calendar Working Hours (tcccp0120m000) session contains multiple time intervals for a single date, and the Available check box is cleared for some intervals and selected for other intervals on the same day, the entire day is unavailable. A calendar recurrence that makes a day unavailable has no effect on the availability of that day in the parent calendar. It is not useful to define a special availability type for unavailability, because ERP LN does not maintain and update the working hours and the capacity data of a calendar in the Calendar Working Hours (tcccp0120m000) session based on non-available availability types.
