			<Paragraph>A <Link href="/baanerp/cp/glossary/glossary#000100" role="glossary">firm-planned</Link> order serves as a sort of additional time fence: SSA ERP does not generate planned orders before the last firm-planned order. If necessary, SSA ERP generates reschedule-in messages. However, you can override this rule by selecting the <GUIRef href="/baanerp/cp/rpd/cprpd0100m000#cprpd000.fipl" role="formfield">Planned Order before Firm/Actual</GUIRef> check box in the <GUIRef href="/baanerp/cp/rpd/cprpd0100m000" role="session">EP Parameters (cprpd0100m000)</GUIRef> session.</Paragraph>

		<GeneralSection><SectionTitle>Simulate in time fence</SectionTitle>
			<Paragraph>If you select the <GUIRef href="/baanerp/cp/rrp/cprrp1210m000#f.sim.in.fence" role="formfield">Generate Within Time Fence</GUIRef> check box, the time fence is ignored and the simulation can start at the current date.</Paragraph>

		<GeneralSection><SectionTitle>Net-change simulation</SectionTitle>
			<Paragraph>If you select the <GUIRef href="/baanerp/cp/rrp/cprrp1210m000#f.net.change.run" role="formfield">Run a Netchange Simulation</GUIRef> check box, the simulation does not start before the <Link href="/baanerp/cp/glossary/glossary#000079" role="glossary">net-change date</Link> (see <Link href="/baanerp/cp/onlinemanual/000026" role="manual">Net-change simulations</Link> ).</Paragraph>

			<Paragraph>SSA ERP determines the end date and time for the simulated time period with the following formula:</Paragraph>
