	<GeneralSection><Paragraph>In SSA ERP, you can use a <Link href="/baanerp/cp/glossary/glossary#000063" role="glossary">time fence</Link> to prevent SSA ERP from making changes in the near-future supply planning.</Paragraph>
		<Paragraph>As a rule, SSA ERP does not overwrite the existing planned orders in the time fence. As a result, SSA ERP 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="formfield">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="formfield">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="formfield">Use Time Fence</GUIRef> check box in the <GUIRef href="/baanerp/cp/rpd/cprpd1100m000" role="session">Items - Planning (cprpd1100m000)</GUIRef> session also impacts whether SSA ERP plans within or outside the time fence.</Paragraph>
		<List><ListIntro>Dependent on the settings of both the <GUIRef href="/baanerp/cp/rrp/cprrp1210m000#f.sim.in.fence" role="formfield">Generate Within Time Fence</GUIRef> check box and the <GUIRef href="/baanerp/cp/rpd/cprpd1100m000#cprpd100.utmf" role="formfield">Use Time Fence</GUIRef> check box, three situation exist:</ListIntro>
