Planning horizon

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

The planning horizon is the time period for which LN maintains planning data for an item.

If you maintain an item master plan for the plan item, the Generate Master Planning (cprmp1202m000) session calculates, among other things, the critical capacity requirements to generate the resource master plans; this calculation takes a considerable amount of system performance. The planning horizon determines over what period LN must calculate the master plans and, therefore the required calculation time.

When you set or change the Planning 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 Planning Horizon field.
