Define Schedule Horizons

Explanation

Use this function to enter new schedule horizon information. Schedule horizons are basic data to support the creation of production schedules. A schedule horizon is used to group parts all having the same production schedule horizon information. When defining schedule horizons, you specify three horizons in terms of working calendar days, schedule horizon, firm horizon, and past due horizon. 

• Schedule Horizon indicates, in days, the amount of planning data, either master scheduling or material requirements planning, that is included on the production schedule.
• Firm Horizon indicates, in days, if some portion of the schedule should be viewed as firm supply by master scheduling or material requirements planning, and thus not re-planned. A firm horizon of zero means that no firm horizon applies.
• Past Due Horizon indicates, in past due days, how much out of date a production schedule can get before it should be deleted.

You also have the option to select whether to roll (move) the orders or not roll (ignore) the orders that occur within the firm planning horizon. The default value is No Roll.

Prerequisites

There are no prerequisites.
