			<List><ListIntro>The plan period of a forecast and the plan period of the actual demand that consumes it do not have to match exactly. A particular instance of actual demand can also consume forecast demand from an earlier period, or forecast demand from a later period. This depends on the values of the following fields in the <GUIRef href="/baanerp/cp/rpd/cprpd4100m000" role="session">Scenarios (cprpd4100m000)</GUIRef> session:</ListIntro>
				<ListItem><GUIRef href="/baanerp/cp/rpd/cprpd4100m000#cprpd400.bdfc" role="formfield">Backward Forecast Consumption</GUIRef>
				</ListItem>
				<ListItem><GUIRef href="/baanerp/cp/rpd/cprpd4100m000#cprpd400.fdfc" role="formfield">Forward Forecast Consumption</GUIRef>
				</ListItem>
			</List>
			<List><ListIntro>Suppose that there is an instance of actual demand in plan period P. The earliest period for consumption is computed as follows:</ListIntro>
				<ListItem>Take the start date of period P</ListItem>
				<ListItem>Subtract the value of the <GUIRef href="/baanerp/cp/rpd/cprpd4100m000#cprpd400.bdfc" role="formfield">Backward Forecast Consumption</GUIRef> field from this period start date, and determine the period B in which the resulting date falls</ListItem>
			</List>
			<List><ListIntro>The latest period for consumption is computed as follows:</ListIntro>
				<ListItem>Take the end date of period P</ListItem>
				<ListItem>Add the value of the <GUIRef href="/baanerp/cp/rpd/cprpd4100m000#cprpd400.fdfc" role="formfield">Forward Forecast Consumption</GUIRef> field to this period and date, and determine the period Y in which the resulting date falls</ListItem>
			</List>
			<List><ListIntro>The consumption proceeds as follows:</ListIntro>
				<ListItem>The actual demand of period P is used to consume the (nonconsumed) forecast in period B.</ListItem>
				<ListItem>If there is still actual demand left, this is used to consume the forecast in period C, and so on.</ListItem>
				<ListItem>If necessary, the consumption process continues until period Y is reached and the forecast of this period is fully consumed.</ListItem>

		<GeneralSection><SectionTitle>Forecast consumption during online ATP updates</SectionTitle>
			<Paragraph>When the ATP is updated online, Enterprise Planning also applies forecast consumption. The result can differ from the normal consumption procedure during a master-plan update, because during an ATP update, the consumption always remains within the bounds of one plan period. In other words, no backward or forward consumption is used.</Paragraph>
