Online phase-number updateIf you select the Online Phase Number Update check box in the Planning Parameters (cprpd0100m000) session, LN immediately updates the phase numbers of items and plan units when a change occurs in a bill of material (BOM) or bill of critical material (BCM). To separately update the phase numbers, use the Compute Phase Numbers (cprpd6200m000) session. During a master-based planning run or an order-based planning run, LN checks whether the phase numbers are correct; if an incorrect phase number is encountered, LN updates the phase numbers and restarts the planning run, if necessary. If you select the Online Phase Number Update check box, LN must do more work if you modify a bill of material (BOM) or bill of critical material (BCM). Therefore, LN needs more time to process these modifications. If you do not update the phase numbers online and you have not used the session to compute phase numbers, a planning run can encounter incorrect phase numbers; this situation delays the planning run. Master-based planning runs and order-based planning runs can suffer from this situation. Recommendations:
