      <Paragraph>Segment schedules are schedules that indicate when the <Link href="/baanerp/ti/glossary/glossary#000073" role="glossary" Update="No">assembly parts</Link> that are required for the work
		in a particular <Link href="/baanerp/ti/glossary/glossary#000019" role="glossary">line segment</Link> must be delivered to the shop floor
		warehouse. For each segment on a line, a range of offline periods is defined.
		And for each period a date is scheduled on which the assembly parts are
		required. Therefore, every <Link href="/baanerp/td/glossary/glossary#ProducVarian_td" role="glossary">product variant</Link> whose requested offline
		date falls in one of these periods requires its assembly parts for the segment
		in question on that date.</Paragraph>
      <ProcedureList>
         <ListIntro>The advantage of these schedules is that the assembly part
		  requirements can be determined right from the schedule, if only the requested
		  offline date of the product variant and the segment of the assembly parts is
		  known. Compare this to the following procedure, which you must use if no
		  segment schedules are used:</ListIntro>
         <ListItem>Determine in which segment a part is required.</ListItem>
         <ListItem>Offset that line segment: calculate the time between the start
		  of the segment and the end of the <Link href="/baanerp/ti/glossary/glossary#000350" role="glossary">roll-off line</Link>.</ListItem>
         <ListItem>Calculate the date on which the assembly part is required.</ListItem>
         <ListItem>Determine the plan period in which this date falls.</ListItem>
         <ListItem>Determine the delivery date of the part, which is the start
		  date of the plan period.</ListItem>
      </ProcedureList>
      <Paragraph>Segment schedules are used for a rough planning of assembly part
		requirements, especially in the more distant future, that is, the period after
		the allocation <Link href="/baanerp/ti/glossary/glossary#000407" role="glossary">time fence</Link>, but before the demand time fence. However,
		the schedules cover the whole period in the demand time fence, including the
		allocation time fence.</Paragraph>
      <Note>
         <SectionTitle>Note</SectionTitle>
         <Paragraph>To prevent that no date can be scheduled for product variants
		  whose requested offline date falls before the first period of a segment, the <GUIRef href="/baanerp/ti/apl/tiapl4500m000#tiapl400.podf" role="manual">Planned Offline Date From</GUIRef> field of the first period
		  of a segment is empty. As a result, the date scheduled of that period applies
		  for all dates before the <GUIRef href="/baanerp/ti/apl/tiapl4500m000#tiapl400.podt" role="manual">Planned Offline Date To</GUIRef>.</Paragraph>

         <ListIntro>The fields in the current session must be read as

         <ListItem>A product variant whose requested offline date falls in this

         <ListItem>These segments occur on the displayed <GUIRef href="/baanerp/ti/apl/tiapl4500m000#tiapl400.asln" role="manual">Assembly Line</GUIRef>. This assembly line is a feeding line
		  to the displayed <GUIRef href="/baanerp/ti/apl/tiapl4500m000#tiapl400.roln" role="manual">Roll-off Line</GUIRef> if the codes of these lines differ. If
		  the codes are equal, the <GUIRef href="/baanerp/ti/apl/tiapl4500m000#tiapl400.asln" role="manual">Assembly Line</GUIRef> is itself the <GUIRef href="/baanerp/ti/apl/tiapl4500m000#tiapl400.roln" role="manual">Roll-off Line</GUIRef>.</ListItem>

         <Paragraph>The <GUIRef href="/baanerp/ti/apl/tiapl2221m000" role="session">Calculate Assembly Part Requirements (tiapl2221m000)</GUIRef> session must use the most up-to-date
		  schedule. Therefore, that session automatically updates the segments if a
		  change is detected that affects the schedules. However, not all changes can be
		  detected automatically. In some cases, the schedule must be updated manually,
