      <Paragraph>To define a <Link href="/baanerp/ti/glossary/glossary#PlanItems_ti" role="glossary">plan item</Link> 's planning horizon, use the <GUIRef href="/baanerp/cp/rpd/cprpd1100m000#cprpd100.ptmf" role="manual">Planning Horizon</GUIRef> field in the <GUIRef href="/baanerp/cp/rpd/cprpd1100m000" role="session">Items - Planning (cprpd1100m000)</GUIRef> session.</Paragraph>
      <Paragraph>The planning horizon is the time period for which ERP Enterprise maintains planning
		data for an item.</Paragraph>
      <Paragraph>If you maintain an <Link href="/baanerp/cp/glossary/glossary#000019" role="glossary">item master plan</Link> for the plan item, the <GUIRef href="/baanerp/cp/rmp/cprmp1202m000" role="session">Generate Master Planning (cprmp1202m000)</GUIRef> session calculates, among other things, the <Link href="/baanerp/cp/glossary/glossary#000097" role="glossary">critical capacity requirements</Link> to generate the <Link href="/baanerp/cp/glossary/glossary#000132" role="glossary">resource master plans</Link>; this calculation takes a
		considerable amount of system performance. The planning horizon determines over
		what period ERP Enterprise must
		calculate the master plans and, therefore the required calculation time.</Paragraph>
      <Paragraph>When you set or change the <GUIRef href="/baanerp/cp/rpd/cprpd1100m000#cprpd100.ptmf" role="manual">Planning Horizon</GUIRef> field, you can run the <GUIRef href="/baanerp/cp/rpd/cprpd1200m000" role="session">Check Horizons (cprpd1200m000)</GUIRef> session to check and optionally adjust the order
		horizon. For details, refer to the field Help of the <Link href="/baanerp/cp/rpd/cprpd1100m000#cprpd100.ptmf" role="formfield">Planning Horizon</Link> field.</Paragraph>
