Calendar bucket priority
Calendar buckets define a value for the calendar. Calendar buckets are effective only during specific periods, specified through:
Start and end date of the validity
Weekdays on which they are effective
Hours between which they are effective
If multiple calendar buckets are effective at the same moment in time, the value with the lowest priority field overrides the others.
A calendar also has a default value that is valid when no calendar bucket is effective.
The above rules allow you to determine the value of a calendar at any moment in time, as illustrated in the example below.
The attached example models a warehouse where the replenishment operations are running on weekdays (Monday through Friday) from 8am till 5pm with a lunch break of an hour. The warehouse is not working on Christmas, December 25th.
A calendar is used to define these working hours. It has 3 calendar buckets, whose effectivity is illustrated in this picture.
At 20 dec 2014 13:00, or any other moment during the weekend, no calendar bucket is effective. The value of the calendar is then 0, the default value.
22 dec 2014 11:00 falls during regular working hours. The value of the calendar is now 1, as the first calendar bucket is effective.
At 23 dec 2014 12:15 the value of the calendar value is 0 again. There are 2 effective calendar buckets at this moment, but the second calendar bucket has the lowest priority value and overrides the other.
At 25 dec 2014 14:00, or any other moment on December 25, the value of the calendar value is also 0. The third calendar bucket has the lowest priority.
