				<ListItem>Do not define more than 50 plan periods.</ListItem>
				<ListItem>If you define plan periods of unequal size, the larger plan periods preferably should be an integer multiple of the smaller plan periods. For example, plan periods of 3 days, 6 days, and 24 days work better than plan periods of 4 days, 7 days, and 30 days.</ListItem>

			<FuncDesc>Select one of the options from the pull-down menu to specify how SSA ERP must determine the period start date.</FuncDesc>
			<SimpleSection><Paragraph>The way SSA ERP determines the start date of the plan period not only depends on the setting of the <GUIRef href="/baanerp/cp/rpd/cprpd4120m000#cprpd420.pest" role="formfield">Period Start</GUIRef> field, but also on whether or not the scenario is a <Link href="/baanerp/cp/glossary/glossary#000006" role="glossary">rolling scenario</Link>.</Paragraph>
				<Paragraph>If you selected the <GUIRef href="/baanerp/cp/rpd/cprpd4100m000#cprpd400.ropl" role="formfield">Rolling Scenario</GUIRef> check box in the <GUIRef href="/baanerp/cp/rpd/cprpd4100m000" role="session">Scenarios (cprpd4100m000)</GUIRef> session, SSA ERP shifts the scenario forward in time when the value of the current date is higher than the sum of the <Link href="/baanerp/cp/glossary/glossary#000022" role="glossary">reference date</Link> and the <Link href="/baanerp/cp/glossary/glossary#000021" role="glossary">rolling frequency</Link>. SSA ERP then shifts the scenario forward in time by the value of the rolling frequency.</Paragraph>
				<Paragraph>When SSA ERP rolls the scenario, it updates the dates of the <Link href="/baanerp/cp/glossary/glossary#000109" role="glossary">plan periods</Link> and redistributes the master-plan quantities over the new <Link href="/baanerp/cp/glossary/glossary#000109" role="glossary">plan periods</Link>.</Paragraph>
				<Paragraph>The rolling scenario functionality applies to the entire scenario, whereas the setting of the <GUIRef href="/baanerp/cp/rpd/cprpd4120m000#cprpd420.pest" role="formfield">Period Start</GUIRef> field only applies to the way that SSA ERP determines the start date of a period with regard to the current date.</Paragraph>
				<Paragraph>If you select a day of the week or a date of the month, SSA ERP only changes the master-plan quantities of the first plan period, as the current date advances. SSA ERP leaves the rest of the plan periods untouched.</Paragraph>
				<Paragraph>If you select <GUIRef href="/baanerp/cp/domains/rpd.pest#rolling" role="enum">Rolling</GUIRef> in the <GUIRef href="/baanerp/cp/rpd/cprpd4120m000#cprpd420.pest" role="formfield">Period Start</GUIRef> field, SSA ERP shifts the plan periods forward in time from the current date by the value of the <GUIRef href="/baanerp/cp/rpd/cprpd4120m000#cprpd420.pety" role="formfield">Period Type</GUIRef> field, and redistributes the master-plan quantities over the shifted plan periods.</Paragraph>
