Calendar Exceptions
D ESCRIPTION
An Exception defines a value that is to be applied for a resource over some fixed period of
time. The exception value overrides the base value defined for the resource. For example,
if a machine’s capacity was scheduled to be available (value of 1) during second shift
according to its base time pattern, you could add an exception to change it to unavailable
for second shift on a particular day (e.g., December 30, 2005).
Exception data are edited via the Exception and Composite windows, which are opened
from the Edit > Calendar Schedules > Exceptions and Display Composite menu
options.
