      <Paragraph>The date on which
      assembly parts are due at the required line station is their planned
      requirement date. The calculation of the planned requirement date depends on
      the value that you entered in the <GUIRef href="/baanerp/ti/asc/tiasc8210m000#ptwf.job.sequence" role="manual">Job Sequence Type</GUIRef> field in the <GUIRef href="/baanerp/ti/asc/tiasc8210m000" role="session">Replenish Shop Floor Warehouse (tiasc8210m000)</GUIRef> session.</Paragraph>

         <ListIntro>You have two choices of how to call off materials:</ListIntro>
         <ListItem>Call off materials based
        on the <Emphasis>planned sequence</Emphasis> of the supply line station. This
        method relies on the planned start times of the line station orders, and
        schedules the assembly line orders based on the start time of the first
        assembly order for the line station. Buffer variations are taken into
        consideration if you define a safety lead time.</ListItem>
         <ListItem>Call off materials based
        on the <Emphasis>actual sequence</Emphasis> of the trigger line station. The
        trigger line station is the line station on which the triggers are fired, and
        is defined in the <Link href="/baanerp/ti/asl/tiasl8100m000" role="session">Process Trigger Definition (tiasl8100m000)</Link> session. In this situation, LN calculates the arrival times of the materials based on the number of line
        stations (between the suppply line station and trigger line station) and on the
        cycle time. In this way, materials are only called off for assembly orders that
        have actually passed the trigger point. This method better reflects the
        actuality of the assembly situation.</ListItem>
