      <Paragraph>In <GUIRef href="/baanerp/cp" role="package">Enterprise Planning</GUIRef>,
      a number of constraints can be imposed on the ordered quantity of a production
      order, purchase order, or distribution order.</Paragraph>

         <Paragraph>You can specify that
        the ordered quantity must be a multiple of 100 units. If you have a requirement
        for 530 units, LN generates an order for 600 units.</Paragraph>
         <Paragraph>You can also specify a
        fixed order quantity of 50 units. If you have a requirement for 530 units, LN generates 11 orders of 50 units each.</Paragraph>

         <Paragraph>If you defined
        warehousing data for the item, and you cleared the <GUIRef href="/baanerp/wh/wmd/whwmd2110s000#whwmd210.uidt" role="manual">Use Item Ordering Data</GUIRef> check box in the <GUIRef href="/baanerp/wh/wmd/whwmd2510m000" role="session">Warehouse - Item (whwmd2510m000)</GUIRef> session, LN uses the warehousing data for lot
        sizing. If you selected the <GUIRef href="/baanerp/wh/wmd/whwmd2110s000#whwmd210.uidt" role="manual">Use Item Ordering Data</GUIRef> check box, LN carries out lot sizing according
        to the value that you specified in the <GUIRef href="/baanerp/tc/ibd/tcibd2100s000#tcibd200.omth" role="manual">Order Method</GUIRef> field
        in the <GUIRef href="/baanerp/tc/ibd/tcibd2500m000" role="session">Items - Ordering (tcibd2500m000)</GUIRef> session. Next, LN sorts out which supply
        source to use, and takes into account the order quantity details of the <GUIRef href="/baanerp/td/ipu/tdipu0110m000" role="session">Items - Purchase Business Partner (tdipu0110m000)</GUIRef> session for purchase orders, or the
        constraints that you set for lot sizing in the <GUIRef href="/baanerp/cp/rpd/cprpd7130m000" role="session">Supplying Relationships (cprpd7130m000)</GUIRef> session for distribution orders.</Paragraph>

      <SectionTitle>Lot sizing of purchase schedule items</SectionTitle>
      <Paragraph>For purchase schedule items, LN devides the purchase part
      of the supply over the available suppliers. Instead of lot sizing the devided
      quantities according to the lot-size settings that you defined for the supplier
      in the <GUIRef href="/baanerp/td/ipu/tdipu0110m000" role="session">Items - Purchase Business Partner (tdipu0110m000)</GUIRef> session, which LN does
      for normal purchase items, LN groups the purchase requirements for purchase
      schedule items according to the delivery moments of the supplier. Next, LN groups the purchase requirements for each supplier to the delivery moments and
      lot sizes the quantities of seperate schedule lines according to the lot-size
      settings in the <GUIRef href="/baanerp/td/ipu/tdipu0110m000" role="session">Items - Purchase Business Partner (tdipu0110m000)</GUIRef> session.</Paragraph>
