      <SectionTitle>Planning with alternative materials</SectionTitle>
      <Paragraph>The <Link href="/baanerp/cp/glossary/glossary#000060" role="glossary">order-based planning</Link> process checks whether the <Link href="/baanerp/cp/glossary/glossary#000046" role="glossary">projected inventory</Link> stays above the <Link href="/baanerp/wh/glossary/glossary#000377" role="glossary">safety stock</Link> if you use the standard material to fulfill
		the material requirement.</Paragraph>
      <Paragraph>If the projected inventory drops below the safety stock, LN searches for a <Link href="/baanerp/cp/glossary/glossary#000100" role="glossary">firm-planned order</Link> that can be rescheduled to an earlier
		date to fill the requirement.</Paragraph>
      <Paragraph>If LN finds no such order, LN checks the <Link href="/baanerp/cp/glossary/glossary#000030" role="glossary">available-to-promise (ATP)</Link> quantity of the component's
		alternative materials (in priority order). If ATP finds an alternative
		material, the material requirement is shifted to that alternative
		material.</Paragraph>
      <Paragraph>If the ATP is insufficient, LN will generate a new <Link href="/baanerp/cp/glossary/glossary#000050" role="glossary">planned order</Link> for the standard material.</Paragraph>
      <Paragraph>If the material requirement cannot be fulfilled in time, LN generates a <Link href="/baanerp/cp/glossary/glossary#000371" role="glossary">signal</Link> to notify the planner.</Paragraph>

         <SectionTitle>Alternative material horizon</SectionTitle>
         <Paragraph>For material requirements in a relatively far future, LN does not check for
		  alternative materials.</Paragraph>
         <Paragraph>To determine how far into the future LN checks for alternative
		  materials, use the <GUIRef href="/baanerp/cp/rpd/cprpd4100m000#cprpd400.almh" role="manual">Alternative Materials Horizon</GUIRef> field in the <GUIRef href="/baanerp/cp/rpd/cprpd4100m000" role="session">Scenarios (cprpd4100m000)</GUIRef> session.</Paragraph>

            <Paragraph>The value of the <Link href="/baanerp/cp/glossary/glossary#415" role="glossary">ATP/CTP horizon</Link> of alternative materials must be greater
			 than the alternative material horizon. Beyond the ATP/CTP horizon, LN assumes that the
			 material is unlimited available.</Paragraph>

         <SectionTitle>Allow multiple materials</SectionTitle>
         <Paragraph>If the <GUIRef href="/baanerp/ti/bom/tibom1110m000#tibom010.almi" role="manual">Allow Multiple Items</GUIRef> check box in the <GUIRef href="/baanerp/ti/bom/tibom1110m000" role="session">Bill of Material (tibom1110m000)</GUIRef> session is selected, LN can distribute the <Link href="/baanerp/ti/glossary/glossary#000057" role="glossary">estimated quantity</Link> of the material over multiple items.</Paragraph>
         <Paragraph>For example, the estimated quantity can be divided over the <Link href="/baanerp/ti/glossary/glossary#000375" role="glossary">use-up material</Link> and the standard material or over the
		  standard material and one or more <Link href="/baanerp/ti/glossary/glossary#000376" role="glossary">alternative materials</Link>.</Paragraph>
         <Paragraph>If you do not permit multiple items, LN makes a choice for
		  each material line: LN issues either the standard material or the alternative material, but not a
		  combination of two or more materials.</Paragraph>

         <ListIntro>The following restrictions apply:</ListIntro>
         <ListItem>The selection of use-up materials and alternative materials is
		  only available in <Link href="/baanerp/cp/glossary/glossary#000060" role="glossary">order-based planning</Link> and not in <Link href="/baanerp/cp/glossary/glossary#000059" role="glossary">master-based planning</Link>
         </ListItem>
         <ListItem>The <Link href="/baanerp/cp/glossary/glossary#000029" role="glossary">capable-to-promise</Link> checks do not take alternative

      <SectionTitle>Phase numbers</SectionTitle>
      <Paragraph>From all items that have the same <Link href="/baanerp/cp/glossary/glossary#000045" role="glossary">phase number</Link>, LN first plans the items that can be used as an
		alternative material, to determine the <Link href="/baanerp/cp/glossary/glossary#000030" role="glossary" Update="No">ATP</Link> of these items.</Paragraph>
      <Paragraph>The phase number of a BOM component must equal the phase number
		of the component's alternative materials. If these phase numbers happen to be
		different, LN first tries
		to adjust the phase numbers to solve that problem. If the BOMs and
		alternative-material definition contains a cycle, a change of phase number
		cannot solve the problem and LN will display an error message.</Paragraph>
      <Paragraph>If LN shows the <GUIRef href="/baanerp/cp/messages/raosign.43" role="message">Alternatives Cycle detected.</GUIRef> error message, use the <GUIRef href="/baanerp/ti/bom/tibom0150m000" role="session">Use Up and Alternative Materials (tibom0150m000)</GUIRef> session to remove the
		alternative material that causes the problem.</Paragraph>

         <List>
            <ListIntro>The following situation is an example of an alternative

            <ListItem>Item A has phase number 0.</ListItem>
            <ListItem>B is a material in the BOM of A (B has phase number
			 1)</ListItem>
            <ListItem>C is a material in the BOM of B (C has phase number
			 2)</ListItem>
            <ListItem>A is an alternative for material C. (A must have the same
			 phase number as C, but A has phase number 0)</ListItem>
         </List>
         <Paragraph>Many other combinations can result in an alternative
		  cycle.</Paragraph>

      <SectionTitle>Checks on the execution level</SectionTitle>
      <Paragraph>You can repeat the check later, after you transferred the orders
		to the <Link href="/baanerp/cp/glossary/glossary#000027" role="glossary">execution level</Link>. In that case, LN will recheck the
		inventory levels and change the selection of materials if
		necessary.</Paragraph>
