         <ListIntro>An assembly order consists of several LSOs. These LSOs are
		  linked to line stations that are grouped in line segments. These orders and
		  segments all have their own start times and end times. These times are
		  calculated on the following occasions:</ListIntro>
         <ListItem>An assembly order is
		  offset when you plan the order, that is, when LAC creates the assembly order in
		  ASC.</ListItem>
         <ListItem>A line segment is offset
		  when you confirm a line sequence in the <Link href="/baanerp/ti/asl/tiasl4200m000" role="session">Simulate and Create Line Sequences (tiasl4200m000)</Link> session.</ListItem>
         <ListItem>An LSO is offset in two
		  instances: <List>
               <ListItem>When you plan the assembly order.</ListItem>
               <ListItem>When you run the current session. This last instance is, of
				course, what we focus on now.</ListItem>
            </List>
         </ListItem>
      </List>
      <List>
         <ListIntro>If you offset LSOs in the current session, the calculation
		  depends on the status of the assembly orders. These statuses are:</ListIntro>
         <ListItem> 
            <GUIRef href="/baanerp/ti/domains/asc.asst#planned" role="option">Planned</GUIRef>. If you only
		  planned an assembly order, and you did not yet confirm a line sequence, the
		  assembly order has the <GUIRef href="/baanerp/ti/domains/asc.asst#planned" role="option">Planned</GUIRef> status.</ListItem>
         <ListItem> 
            <GUIRef href="/baanerp/ti/domains/asc.asst#sequenced" role="option">Sequenced</GUIRef>. After you
		  confirm a line sequence, the assembly order has the <GUIRef href="/baanerp/ti/domains/asc.asst#sequenced" role="option">Sequenced</GUIRef> status.</ListItem>
      </List>
      <List>
         <ListIntro>According to these statuses, offsetting is based on the
		  following information:</ListIntro>
         <ListItem>For <GUIRef href="/baanerp/ti/domains/asc.asst#planned" role="option">Planned</GUIRef> assembly orders,
		  the calculation is based on the lead-time of the line segments, as defined in
		  the <Link href="/baanerp/ti/asl/tiasl1540m000" role="session">Line Segments (tiasl1540m000)</Link> session.</ListItem>
         <ListItem>For <GUIRef href="/baanerp/ti/domains/asc.asst#sequenced" role="option">Sequenced</GUIRef> assembly
		  orders, the calculation is based on the sequence, assembly line calendar, and
		  the assembly assignments of the assembly line.</ListItem>
      </List>
      <List>
         <ListIntro>The previous information implies that the start times and end
		  times of LSOs can vary, according to the offset method that is used. Therefore,
		  an LSO can have start times and end times on one of the following three levels:</ListIntro>
         <ListItem>If the LSOs of a <GUIRef href="/baanerp/ti/domains/asc.asst#planned" role="option">Planned</GUIRef> assembly order are
		  not yet offset in the current session, they have the start times and end times
		  of the assembly order. Of course these values are initial values that cannot be
		  calculated in the current session.</ListItem>
         <ListItem>If you offset LSOs for
		  assembly orders with the <GUIRef href="/baanerp/ti/domains/asc.asst#planned" role="option">Planned</GUIRef> status, these LSOs get the same start times and
		  end times as the line segments. This is because the start times and end times
		  of the LSOs are calculated, based on the lead-times of the line
		  segments.</ListItem>
         <ListItem>If you offset LSOs for
		  assembly orders with the <GUIRef href="/baanerp/ti/domains/asc.asst#sequenced" role="option">Sequenced</GUIRef> status, these LSOs receive the start times and
		  end times of the line stations.</ListItem>
      </List>
      <List>
         <ListIntro>To offset LSOs in the current session, you must specify a
		  range, an <GUIRef href="/baanerp/ti/asl/tiasl4230m000#offline.date" role="manual">Offline Date To</GUIRef>, and
		  the order type for which the LSOs must be offset. However, not all assembly
		  orders that match these criteria are offset, but only those assembly orders
		  that require offsetting. Assembly orders that require offsetting have the
		  Offsetting Required check box selected. This check box is displayed in the
		  following sessions:</ListIntro>
         <ListItem>For <GUIRef href="/baanerp/ti/domains/asc.asst#planned" role="option">Planned</GUIRef> orders, in the <Link href="/baanerp/ti/asc/tiasc2100s000" role="session">Assembly Order (tiasc2100s000)</Link> session, on
		  the General tab. If the <GUIRef href="/baanerp/ti/asc/tiasc2100s000#tiasc200.asst" role="manual">Assembly Order Status</GUIRef> is not <GUIRef href="/baanerp/ti/domains/asc.asst#planned" role="option">Planned</GUIRef>, the <GUIRef href="/baanerp/ti/asc/tiasc2100s000#tiasc200.ofst" role="manual">Offsetting Required</GUIRef> check box is not displayed.</ListItem>
         <ListItem>For <GUIRef href="/baanerp/ti/domains/asc.asst#sequenced" role="option">Sequenced</GUIRef> orders, in the <GUIRef href="/baanerp/ti/asl/tiasl4500m000" role="session">Line Segment - Line Sequence (tiasl4500m000)</GUIRef> session.</ListItem>
      </List>
      <List>
         <ListIntro>Offsetting is required as soon as a change in the dates or
		  times of an order occurs, or, in other words, as soon as the actual dates and
		  times no longer match the planned dates and times. The Offsetting Required
		  check box, therefore, is selected in the following instances:</ListIntro>
         <ListItem>When LAC generates the
		  assembly order in ASC.</ListItem>
         <ListItem>If you mix or manually
		  move planned orders and, as a result, these orders receive another offline
		  date/time.</ListItem>
         <ListItem>If you offset the LSOs
		  of a parent order and as a result, this order receives another offline
		  date/time, the check box is selected for the child orders; because the child
		  orders must be synchronized with the parent order. Note that offsetting the
		  LSOs of a parent order does not result in new start times and end times for the
		  LSOs of the child orders. The LSOs of the child orders must be offset
		  themselves too.</ListItem>
         <ListItem>If you confirm a line
		  sequence, in the <Link href="/baanerp/ti/asl/tiasl4200m000" role="session">Simulate and Create Line Sequences (tiasl4200m000)</Link> session, or manually change a confirmed line sequence,
		  the line segments receive new start times and end times. As a result,
		  offsetting is required for the LSOs. If the order has child orders, the check
		  box is selected for the child orders too; because the child orders must be
		  synchronized with the parent order.</ListItem>
      </List>
      <Paragraph>Note that in all these
		instances, it is necessary to offset the LSOs of the orders in question, using
		the current session. The error messages for offsetting can be viewed in the <Link href="/baanerp/ti/asc/tiasc0501m000" role="session">Assembly Messages (tiasc0501m000)</Link> session.</Paragraph>
