A project schedule in Oracle Project Management Cloud defines the working and non-working times for a project. It is constructed from three main elements. The question already mentions Shifts, which define working hours within a day (e.g., 8 AM to 5 PM). The other two core elements are Workday Patterns, which define a repeating sequence of shifts over a period (e.g., Monday to Friday work), and Exceptions, which are used to override the standard pattern for specific dates, such as public holidays or special non-working days.

B. Accounting Calendar: This is a financial calendar used for defining accounting periods for posting transactions to the general ledger, not for project work time.

D. Time Off: While employee time off affects resource availability, it is typically managed in HCM and reflected as an exception on a calendar, not a fundamental building element of the schedule itself.

E. Expenditure Type: This is a classification for project costs (e.g., Labor, Materials) and is unrelated to defining project schedules or working time.

and Shifts: How They Work Together". This section details that a schedule is composed of a workday pattern

which in turn is composed of shifts

and can be modified by exceptions.
