Create Calendar
General
A calendar in IFS Applications defines: 
	- The days that are available (for working, delivery, etc.), e.g., May 17th, 
	May 18th, May 21st...
- When the facility, business, etc., is open (for working delivery, etc.), 
	e.g. May 17th from 8.00am - 11.00am...
Several calendars can be defined. These can then be connected to different business 
objects in IFS Applications, e.g., Site, Work Center, Project... The usage of calendar 
differs but typical questions to the Calendar are: 
	- The lead time for this part is 10 days. When do I have to order it if I 
	want it by this date.
- This manufacturing operation takes 14 hours. When will I be finished if 
	I start today at noon?
- What periods exists on this day?
- How many working minutes are between two times?
The definition of a calendar in IFS Applications is done by defining rules. Those 
rules are: Day Types, Schedules, Schedule Exceptions. 
	- A Calendar is defined by connecting Schedules and Schedule Exceptions.
	
- A Schedule describes a series of Day Types that repeats after a given number 
	of days, e.g. 7 days Schedule. 
- A Schedule Exception defines exception to the Schedule. This is done by 
	connecting Day Types with specific dates.
- A Day Type define how a specific day looks like (working time). All working 
	time is connected to a Period.
This information is then used by different parts of IFS Applications
