      <Paragraph>For a divergent supply line structure, multiple parent lines can
		synchronize with the same <Link href="/baanerp/ti/glossary/glossary#000097" role="glossary">supply line</Link>. In such a scenario, for each <Link href="/baanerp/tp/glossary/glossary#000319" role="glossary">assembly order</Link>, the supply line must be synchronized with the parent line only
		after the system determines that the supply line is part of the <Link href="/baanerp/ti/glossary/glossary#000000000000055" role="glossary">assembly line</Link> model required to assemble the configured
		end item. The system determines the inclusion of the supply line based on the <GUIRef href="/baanerp/ti/asl/tiasl1530m000#tiasl130.cfdp" role="manual">Configuration Dependent</GUIRef> parameter</Paragraph>

   <GeneralSection>
      <Paragraph>After the assembly order sequence for a parent line is
		generated, the sequence of the parent line segment must be synchronized with
		the sequence of the linked last segment of the supply line. If the parent line
		segment is linked to multiple supply lines, then the sequence of the parent
		line segment must be synchronized with the sequence of last segment of every
		supply line that supplies to that parent line segment.</Paragraph>
      <Paragraph>A parent line synchronizes with the supply line to fix the
		sequence of the assembly orders on the supply line. As a result of this
		synchronization, the end date of the <Link href="/baanerp/ti/glossary/glossary#000311" role="glossary">line station order (LSO)</Link> of the last <Link href="/baanerp/ti/glossary/glossary#LineStatio_ti" role="glossary">line station</Link> of the last <Link href="/baanerp/ti/glossary/glossary#000019" role="glossary">line segment</Link> of the <Link href="/baanerp/ti/glossary/glossary#000097" role="glossary">supply line</Link> connected to the parent line, is set to the start date of the <Link href="/baanerp/ti/glossary/glossary#000311" role="glossary">LSO</Link> on
		the linked line station of the parent line.</Paragraph>
      <Paragraph>Therefore, in a scenario where multiple parent lines synchronize
		with a single supply line, the <Emphasis>First come - First serve</Emphasis> concept is used to determine a <Emphasis>fixed</Emphasis> position for assembly
		orders on the supply line. This fixed sequence cannot be changed even if the
		supply line is re-sequenced at a later stage, for another parent line.</Paragraph>
      <Paragraph>When another parent line is sequenced and synchronized with the
		same supply line, the previously fixed positions of the assembly orders are not
		changed. The synchronization process tries to fix the assembly orders in a
		position as close as possible to the start date of the LSO, on the linked line
		station of the parent line.</Paragraph>
      <Paragraph>The search for a position is limited to 30 days. If the assembly
		order cannot be fixed in a position which is closest to the requirement date of
		the LSO of the line station, the system backdates the search for an available
		position to fix the assembly order until 30 days before the start date. If the
		order cannot be fixed within the 30 days, the assembly order is fixed in an
		available position, at a date in the future, surpassing the requirement date. A
		message is displayed stating that the synchronization is not completed
		succesfully.</Paragraph>
      <Paragraph>When a parent line is re-sequenced, the fixed assembly orders on
		the supplying line, related to this parent line are removed. The orders must be
		inserted again when the supply line is synchronized after re-sequencing the
		parent line. The positions, available on the supply line, are searched again.
		All other fixed assembly orders on the supply line, related to other parent
		lines, are not affected.</Paragraph>
