| # Checking Horizons The calculations are based on: Cumulative order lead times Synchronization between order horizons at various BOM levels In the Update Method field, you can choose between three update methods. Regardless of the method you choose, the COLT values (that is, the COLT and the noncritical COLT in the Items - Planning (cprpd1100m000) session) are always updated. You must select the Automate Update Horizons check box in the Items - Planning (cprpd1100m000) session, for the items for which you want ERP LN to update the order horizon and the planning horizon. The difference between the three update methods is: COLT: creates a report on the order horizons and planning horizons that are too small, but does not actually update these horizons. COLT + Horizons When Too Small: updates the order horizons and planning horizons that are too small COLT + All Horizons: updates all order horizons and planning horizons, resetting them to their minimum levels Note The COLT calculation takes into account the values that you specify in the following fields: Additional Lead Time Order Lead-Time Multiplier Related topics Lead times and horizons Cumulative order lead times and horizons Master planning, an overview To maintain an item master plan To update master-plan data To maintain a resource master plan |
