Order horizon

To define a plan item 's order horizon, use the Order Horizon field in the Items - Planning (cprpd1100m000) session.

The order horizon is the time period for which Enterprise Planning uses order-based planning to plan supply.

The Generate Order Planning (cprrp1210m000) session, that performs the order-based planning, also performs the capacity planning for the planned orders. To calculate the capacity utilization, LN matches the routing lead times against the calendar; this takes a lot of processor time and is performance sensitive. If the order horizon is very long, the planning run's performance slows down.

A reasonable minimum value for the order horizon is the cumulative order lead time.

When you set or change the Order Horizon field, you can run the Check Horizons (cprpd1200m000) session to check and optionally adjust the order horizon. For details, refer to the field Help of the Order Horizon field.
