In Oracle Time & Labor, you can define the following time structures that, together, define the hours that you expect your workers to be working each week:

• Holiday Calendars

  Holiday calendars allow the system to recognize paid and unpaid holidays. Holiday calendars are part of an earning policy.

• Shifts

  Shifts define the duration or time-in and time-out of work schedules. Shifts are a building block for work plans and must be defined first.

• Work plans

  Work plans identify applicable shifts for each of the seven days of the week. Work plans are a building block of rotation plans.

• Rotation plans

  Rotation plans identify the dates on which an employee moves from one work plan to another.

Notice that these structures are hierarchical, so you must define them in the order listed above.

In addition, you can define the following structures for reporting purposes:

• Project Accounts, which you use to input time and/or dollar estimates for tasks and work orders.

• Variances, which define low, average, and high levels of hours you expect to see recorded each period for a selected organization, location, or earning type.

• Earnings groups, which you use group earnings together for reporting purposes. You can also use earning groups to identify the earning types for which you accumulate hours to compare with weekly overtime limits you define on the earning policy.
