      <Paragraph>If an item has no <Link href="/baanerp/cp/glossary/glossary#000019" role="glossary">item master plan</Link>, the only

      <Paragraph>You can enter special
		demand for an item or item/channel combination in the <GUIRef href="/baanerp/cp/dsp/cpdsp2100m000" role="session">Special Demand by Item (cpdsp2100m000)</GUIRef> session.</Paragraph>
      <Paragraph>LN automatically applies forecast consumption

            <ListIntro>The dates of the forecast demand and 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 moment, or forecast
			 demand from a later moment. This depends on the values of the following fields

            <Paragraph>Suppose that there
			 is an instance of actual demand on date (and time) P. The starting moment for
			 consumption (B) is P minus the value of the <GUIRef href="/baanerp/cp/rpd/cprpd4100m000#cprpd400.bdfc" role="manual">Backward Forecast Consumption</GUIRef> field. The end moment for consumption (Y) is P plus the

            <Paragraph>The starting moment (B) is rounded to the start of the day
			 (time 00:00:00). The end moment (Y) is rounded to the end of the day.

			 demand of a single day.</Paragraph>
            <List>
               <ListIntro>The consumption proceeds as follows:</ListIntro>
               <ListItem>The actual demand
				at moment P is used to consume the earliest occurrence of (nonconsumed)
				forecast on or after moment B.</ListItem>
               <ListItem>If there is still
				actual demand left, this is used to consume the next forecast occurrence, and
				so on.</ListItem>
               <ListItem>If necessary, the
				consumption process continues until moment Y is reached, and all forecast
				between B and Y has been fully consumed.</ListItem>
            </List>
         </ExampleSection>
         <Paragraph>This consumption
		  procedure takes place in two phases.</Paragraph>
      </GeneralSection>
      <GeneralSection>
         <SectionTitle>Phase 1</SectionTitle>
         <Paragraph>In this step, only
		  customer demand that falls in a <Link href="/baanerp/tc/glossary/glossary#000016" role="glossary">channel</Link> is considered. This
		  demand is used to consume the special demand defined for a particular
		  item/channel combination.</Paragraph>

         <SectionTitle>Phase 2</SectionTitle>
         <List>
            <ListIntro>In this step, all remaining actual demand is considered:</ListIntro>
            <ListItem>Remaining
			 channel-specific demand after all channel-specific forecast has been consumed.</ListItem>
            <ListItem>Actual customer demand
