| # Online phase-number update If you select the Online Phase Number Update check box in the EP 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: Clear the Online Phase Number Update check box in the EP Parameters (cprpd0100m000) session and, if you perform a planning run after modifying a BOM or BCM, run the Compute Phase Numbers (cprpd6200m000) session first. If you do not want to run the Compute Phase Numbers (cprpd6200m000) session before every planning run if a BOM might have been modified, select the Online Phase Number Update check box in the EP Parameters (cprpd0100m000) session.
