      <Paragraph>A product variant structure defines the structure of a specific
		configured item by specifying the relations between this item and the <Link href="/baanerp/ti/glossary/glossary#GeneriItem_ti" role="glossary" Update="No">generic items</Link> and <Link href="/baanerp/ti/glossary/glossary#000401" role="glossary">engineering modules</Link> that make up this item. Generic
		sub-items can also have their own sub-items and/or engineering modules. The
		level below the engineering modules is specified in the <Link href="/baanerp/ti/glossary/glossary#000408" role="glossary" Update="No">flattened</Link> 
         <Link href="/baanerp/ti/glossary/glossary#000073" role="glossary" Update="No">assembly parts</Link>, which appears in the <GUIRef href="/baanerp/ti/apl/tiapl2520m000" role="session">Flattened Assembly Parts and Operations (tiapl2520m000)</GUIRef> session.</Paragraph>
      <List>
         <ListIntro>The product variant structure is created on the following
		  moments:</ListIntro>
         <ListItem>When the <Link href="/baanerp/td/glossary/glossary#ProducVarian_td" role="glossary">product variant</Link> is entered and saved, the
		  product variant structure is created, in regard to the relation between the
		  main item and the generic sub items.</ListItem>
         <ListItem>When you run the <GUIRef href="/baanerp/ti/apl/tiapl3210m000" role="session">Generate Product Variant Structures (tiapl3210m000)</GUIRef>) session, the product variant
		  structure is created, in regard to the relation between the main item and the
		  engineering modules. Note, however, that this only happens if the <GUIRef href="/baanerp/ti/apl/tiapl0100s000#tiapl000.epvs" role="manual">External Product Variant Structure</GUIRef> check box is
		  cleared in the details of the <GUIRef href="/baanerp/ti/apl/tiapl0500m000" role="session">Assembly Planning Parameters (tiapl0500m000)</GUIRef> session. <List>
               <ListIntro>If required, the product variant structure can also be
				generated by the following sessions:</ListIntro>

      <List>
         <ListIntro>The generic items and engineering modules are retrieved from

         <ListItem>The <Link href="/baanerp/ti/glossary/glossary#BillOfMateri_ti" role="glossary">bill of material (BOM)</Link> relations to

         <ListItem>The BOM relations to engineering modules are either copied from
		  the item's template, or delivered by an external source, which depends on the

If this check box is selected, the BOM relations to engineering modules are delivered
		  from an external source. LN provides no functionality to copy the engineering modules from an
		  external source to the product variant structure. If this check box is cleared, the BOM relations to engineering modules are copied from
		  the item's template, which is defined in the <GUIRef href="/baanerp/ti/apl/tiapl2510m000" role="session">Generic Bill of Material (tiapl2510m000)</GUIRef> session.</ListItem>
      </List>
      <Paragraph>The information that is retrieved from the <Link href="/baanerp/cf/glossary/glossary#000020" role="glossary">generic BOM</Link> is selected, based on the <Link href="/baanerp/tc/glossary/glossary#000304" role="glossary">effectivity unit</Link> of the product variant, and the
		effective and expiry dates. The date range is evaluated against the <GUIRef href="/baanerp/ti/apl/tiapl3100s000#tiapl300.pcfd" role="manual" Update="No">Product Configuration Date</GUIRef>, which is displayed in the
