      <Paragraph>To define a <Link href="/baanerp/ti/glossary/glossary#PlanItems_ti" role="glossary">plan item's</Link> fixed lead-time horizon, use the <GUIRef href="/baanerp/cp/rpd/cprpd1100m000#cprpd100.fltm" role="manual">Start of Fixed Lead-Time Horizon (SFC)</GUIRef> field in the <GUIRef href="/baanerp/cp/rpd/cprpd1100m000" role="session">Items - Planning (cprpd1100m000)</GUIRef> session. The <GUIRef href="/baanerp/cp/rpd/cprpd1100m000#cprpd100.fltm" role="manual">Start of Fixed Lead-Time Horizon (SFC)</GUIRef> field is used
		only for planned production orders.</Paragraph>
      <Paragraph>The fixed lead-time horizon is the time period for which <GUIRef href="/baanerp/cp" role="package">Enterprise Planning</GUIRef> uses a
		fixed lead time to plan orders.</Paragraph>
      <Paragraph>Before the fixed lead-time horizon, <GUIRef href="/baanerp/cp" role="package">Enterprise Planning</GUIRef> plans on
		the basis of routing data. Beyond the fixed lead-time horizon, <GUIRef href="/baanerp/cp" role="package">Enterprise Planning</GUIRef> plans
		orders by using a fixed lead time.</Paragraph>
      <Paragraph>The fixed lead-time horizon applies especially to <Link href="/baanerp/td/glossary/glossary#ManufaItem_td" role="glossary">manufactured items</Link>. Beyond the fixed lead-time horizon,
		the planning run does not calculate or store operations during the planning
		run. Instead, the planning run uses the plan item's <Link href="/baanerp/cp/glossary/glossary#000057" role="glossary">fixed lead time</Link> to calculate the start and finish date of
		planned orders. The orders without operations cannot be transferred to <GUIRef href="/baanerp/ti/sfc" role="module">Shop Floor Control</GUIRef> module; which means the planned production orders can be transferred, if the
		order is within the fixed lead time horizon.</Paragraph>
      <Paragraph>The fixed lead time is taken from the <Link href="/baanerp/tc/glossary/glossary#000010" role="glossary">order lead time</Link> specified in the <GUIRef href="/baanerp/ti/ipd/tiipd0101m000" role="session">Items - Production (tiipd0101m000)</GUIRef> session, which is calculated based on the routing and <Link href="/baanerp/tc/glossary/glossary#000060" role="glossary">economic order quantity</Link>.</Paragraph>
      <Paragraph>Planning with a fixed lead time is faster than planning on the
		basis of routing data, but the results are less precise.</Paragraph>

      <Paragraph>For the planned purchase orders, you must define the <Link href="/baanerp/ti/glossary/glossary#PlanItems_ti" role="glossary">plan item's</Link> fixed lead-time horizon, in the <GUIRef href="/baanerp/td/ipu/tdipu0110m000" role="session">Items - Purchase Business Partner (tdipu0110m000)</GUIRef> session. The lead time is defined in

      <Paragraph>To make a rough and faster calculations for the planned purchase
