      <Paragraph>If you select the <Link href="/baanerp/cp/rpd/cprpd0100m000#cprpd000.opup" role="formfield">Online Phase Number Update</Link> check box in the <GUIRef href="/baanerp/cp/rpd/cprpd0100m000" role="session">Planning Parameters (cprpd0100m000)</GUIRef> session, ERP Enterprise immediately updates the <Link href="/baanerp/cp/glossary/glossary#000045" role="glossary" Update="No">phase numbers</Link> of
		items and plan units when a change occurs in a <Link href="/baanerp/ti/glossary/glossary#BillOfMateri_ti" role="glossary"

      <Paragraph>To separately update the phase numbers, use the <GUIRef href="/baanerp/cp/rpd/cprpd6200m000" role="session">Compute Phase Numbers (cprpd6200m000)</GUIRef> session.</Paragraph>
      <Paragraph>During a <Link href="/baanerp/cp/glossary/glossary#000059" role="glossary">master-based</Link> planning run or an <Link href="/baanerp/cp/glossary/glossary#000060" role="glossary">order-based</Link> planning run, ERP Enterprise checks whether the
		phase numbers are correct; if an incorrect phase number is encountered, ERP Enterprise updates the phase
		numbers and restarts the planning run, if necessary.</Paragraph>

      <Paragraph>If you select the <GUIRef href="/baanerp/cp/rpd/cprpd0100m000#cprpd000.opup" role="manual">Online Phase Number Update</GUIRef> check box, ERP Enterprise must do more work if
		you modify a <Link href="/baanerp/ti/glossary/glossary#BillOfMateri_ti" role="glossary"
               Update="No">bill of material (BOM)</Link> or <Link href="/baanerp/ti/glossary/glossary#000081" role="glossary" Update="No">bill of critical material (BCM)</Link>. Therefore, ERP Enterprise needs more time to process these modifications.</Paragraph>
      <Paragraph>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. <Link href="/baanerp/cp/glossary/glossary#000059" role="glossary">Master-based</Link> planning runs and <Link href="/baanerp/cp/glossary/glossary#000060" role="glossary">order-based</Link> planning runs can suffer from this situation.</Paragraph>
