Note: You are associating a time pattern with one workcell only. If you want to associate the
time pattern with all the workcells, you will need to make this association with each workcell
separately.
Step 3 • Schedule exceptions
A Composite Time Pattern may have exceptions that define irregular, but expected,
changes to the normal schedule. These exceptions may be outages (unavailable times)
such as holidays or planned maintenance periods, or additional available times such as
overtime hours or extended seasonal hours.
As an example, below are the steps needed to schedule an exception for New Year’s Day.
1. Display the Composite Time Patterns dialog. Expand the tree for the first workcell and
click on the Capacity entry. Right-click on the Exceptions grid and select New...
from the shortcut menu to display the Exceptions dialog.
2. Enter New Year’s Day in the Description box.
3. Select State from the Value Type box and Unavailable from the Value box.
4. Specify this exception as starting on January 1, 2005 at 0 and ending on January 2,
2005 at 0.
