| To recompute phase numbers |  |
| The phase numbers can be recalculated manually or automatically. You can recalculate the phase numbers manually with the Compute Phase Numbers (cprpd6200m000) session. If the Online Phase Number Update check box in the EP Parameters (cprpd0100m000) session is selected, ERP LN updates the phase numbers online whenever there is a change in either: The bill of material (BOM) The bill of critical materials (BCM) The supplying relationships Note Online updating of phase numbers reduces the system performance, especially when you enter or generate a large number of BOM lines or BCM lines at once. The difference between the phase numbers for master planning and the phase numbers for order planning is: Master-planning phase numbers are based on the BCMs, whereas order-planning phase numbers are based on the BOMs. Master-planning phase numbers take the plan units into account.
