      <Paragraph>In ERP Enterprise, you can use a <Link href="/baanerp/cp/glossary/glossary#000063" role="glossary">time fence</Link> to prevent ERP Enterprise from making changes in the
      near-future supply planning.</Paragraph>
      <Paragraph>As a rule, ERP Enterprise does
      not overwrite the existing planned orders in the time fence. As a result, ERP Enterprise only generates planned orders beyond the time fence when you carry out
      the <GUIRef href="/baanerp/cp/rrp/cprrp1210m000" role="session">Generate Order Planning (cprrp1210m000)</GUIRef> or beyond the <Link href="/baanerp/cp/glossary/glossary#000067" role="glossary">forecast time fence</Link> when you carry out the <GUIRef href="/baanerp/cp/rmp/cprmp1202m000" role="session">Generate Master Planning (cprmp1202m000)</GUIRef> session.</Paragraph>
      <Paragraph>To ignore the time fence
      for order planning, you can select the <GUIRef href="/baanerp/cp/rrp/cprrp1210m000#f.sim.in.fence" role="manual">Generate Within Time Fence</GUIRef> check box in the <GUIRef href="/baanerp/cp/rrp/cprrp1210m000" role="session">Generate Order Planning (cprrp1210m000)</GUIRef> session. Enterprise Planning then
      simulates the order planning for the selected range of paln items within the
      time fence and overwrites the existing planned orders.</Paragraph>
      <Paragraph>In addition to the <GUIRef href="/baanerp/cp/rrp/cprrp1210m000#f.sim.in.fence" role="manual">Generate Within Time Fence</GUIRef> check box in the <GUIRef href="/baanerp/cp/rrp/cprrp1210m000" role="session">Generate Order Planning (cprrp1210m000)</GUIRef> session, the settings of the <GUIRef href="/baanerp/cp/rpd/cprpd1100m000#cprpd100.utmf" role="manual">Use Time Fence</GUIRef> check box in the <GUIRef href="/baanerp/cp/rpd/cprpd1100m000" role="session">Items - Planning (cprpd1100m000)</GUIRef> session also impacts whether ERP Enterprise plans within or
      outside the time fence.</Paragraph>
