      <Paragraph>This section describes how LN selects the items to
		plan in the <GUIRef href="/baanerp/cp/rrp/cprrp1210m000" role="session">Generate Order Planning (cprrp1210m000)</GUIRef> session and the <GUIRef href="/baanerp/cp/rrp/cprrp1220m000" role="session">Generate Order Planning (Item) (cprrp1220m000)</GUIRef> session.</Paragraph>

      <SectionTitle>Net-change planning</SectionTitle>
      <Paragraph>For each plan item, LN records if a change has occurred since the
		last simulation, for example, a change in the bill of material or changed
		demand figures. LN also
		records the earliest date on which a change has occurred ( <Link href="/baanerp/cp/glossary/glossary#000079" role="glossary">net change date</Link>).</Paragraph>
      <Paragraph>You can have the order-planning sessions to plan only the items
		for which planning data changed since the last planning run.</Paragraph>

   <GeneralSection>
      <SectionTitle>Bottom-up item selection</SectionTitle>
      <Paragraph>To investigate the effects of a change in availability of some
		critical component that is used in many end products, you can use the bottom-up
		item-selection feature.</Paragraph>
      <Paragraph>In a bottom-up planning run, the LN plans every item that
		somehow relies on the availability of the originally selected plan item.</Paragraph>
   </GeneralSection>
   <GeneralSection>
      <SectionTitle>Top-down item selection</SectionTitle>
      <Paragraph>To perform a complete planning run for some high-priority sales
		order, for example, for a sophisticated customized (engineer-to-order) end
		item, you can use the top-down item-selection feature.</Paragraph>
      <Paragraph>In a top-down planning run, LN plans every purchased
		item and subassembly of which the timely availability can influence the
		production of the originally selected plan item.</Paragraph>

      <List>
         <ListIntro>LN applies the following restrictions to the selection of plan items, for which LN generates the order

         <ListItem>Both top-down and bottom-up select the related items on one <Link href="/baanerp/tc/glossary/glossary#000046" role="glossary">site</Link>. The selection algorithm stops as soon as it

         <ListItemHead>Selection range</ListItemHead>
         <ListItem>LN selects the plan item you specified in the <GUIRef href="/baanerp/cp/rrp/cprrp1220m000" role="session">Generate Order Planning (Item) (cprrp1220m000)</GUIRef> session or the range of plan items you

            <Paragraph>The bottom-up selection works in a multilevel way. For

                  <Paragraph>Derived-from items: The generic or normal items that you

				  Manufacturing, and from which the project items included in the specified item
				  range are derived.</Paragraph>
                  <Paragraph>If, during the order-based planning, the project
				  structure of a project item must be built up, this also works together with the
				  top-down item selection algorithm. For example, if during order-based planning, LN finds out that supply
				  must be generated for project item PX, LN copies the structure
				  of item X. In that case, LN must also create new project items. These
				  newly created project items are also taken into account during the planning.</Paragraph>
