      <Paragraph>The supply source of the <Link href="/baanerp/cp/glossary/glossary#000054" role="glossary">clustered item</Link> is purchase, if you set the <GUIRef href="/baanerp/cp/rpd/cprpd1100m000#cprpd100.sour" role="manual">Default Supply Source</GUIRef> field in the <GUIRef href="/baanerp/cp/rpd/cprpd1100m000" role="session">Items - Planning (cprpd1100m000)</GUIRef> session to Production/Purchase, and LN sets the <GUIRef href="/baanerp/cp/rpd/cprpd1100m000#actual.sour" role="manual">Actual Source</GUIRef> field to
      Purchase. This occurs if the current moment falls in a period for which you set
      the <GUIRef href="/baanerp/tc/ibd/tcibd0101s000#tcibd001.kitm" role="manual">Item Type</GUIRef> field of the
      date effectivity line that you defined in the <GUIRef href="/baanerp/tc/ibd/tcibd0510m000" role="session">Date-Effective Item Data (tcibd0510m000)</GUIRef> session to Purchase.</Paragraph>
      <Paragraph>For purchased plan
      items, you must define the necessary data to enable <GUIRef href="/baanerp/cp" role="package">Enterprise Planning</GUIRef> to create <Link href="/baanerp/cp/glossary/glossary#000048" role="glossary">planned purchase orders</Link>, and because plan items with a <Link href="/baanerp/cp/glossary/glossary#000315" role="glossary">cluster</Link> only exist in Enterprise Planning, you
      define purchase data in the <GUIRef href="/baanerp/td/ipu/tdipu0101m000" role="session">Items - Purchase (tdipu0101m000)</GUIRef> session and the <GUIRef href="/baanerp/td/ipu/tdipu0110m000" role="session">Items - Purchase Business Partner (tdipu0110m000)</GUIRef> session for the general item.
      Clustered plan items also use these data.</Paragraph>
      <Paragraph>An option for purchased
      plan items is to specify <Link href="/baanerp/cp/glossary/glossary#000107" role="glossary">priority rules</Link> in the <GUIRef href="/baanerp/cp/rpd/cprpd7120m000" role="session">Supply Strategy (cprpd7120m000)</GUIRef> session, if LN must make a selection out of
      multiple suppliers when the item is supplied by more than one. Contrary to
      other purchase settings, you can specify <Link href="/baanerp/cp/glossary/glossary#000105" role="glossary">supply strategies</Link> on the level of a clustered plan item.</Paragraph>
      <Paragraph>Essentially, <GUIRef href="/baanerp/cp" role="package">Enterprise Planning</GUIRef> performs purchase planning for clustered plan items in an identical way as for
      non-clustered plan items, because they use the same supplier data. The only
      data you can define on the level of a cluster are supply strategies.</Paragraph>
      <Paragraph>However, an additional
      feature exists to select suppliers based on the cluster. To do so, you can use
      the <GUIRef href="/baanerp/tc/com/tccom4121s000#tccom121.cwar" role="manual">Warehouse</GUIRef> field on the
      Shipping tab of the <GUIRef href="/baanerp/tc/com/tccom4121s000" role="session">Ship-from Business Partner (tccom4121s000)</GUIRef> session. If you specify a <Link href="/baanerp/tc/glossary/glossary#Warehouse_tc" role="glossary">warehouse</Link> in this field, the supplier can only deliver
      the goods to this warehouse. <GUIRef href="/baanerp/cp" role="package">Enterprise Planning</GUIRef> only takes into account the corresponding supplier
      during planning when the default warehouse of a clustered plan item is equal to
      the warehouse that you defined in the <GUIRef href="/baanerp/tc/com/tccom4121s000#tccom121.cwar" role="manual">Warehouse</GUIRef> field in the <GUIRef href="/baanerp/tc/com/tccom4121s000" role="session">Ship-from Business Partner (tccom4121s000)</GUIRef> session.</Paragraph>
      <Paragraph>An example of the use of
      clustered components in the <Link href="/baanerp/ti/glossary/glossary#BillOfMateri_ti" role="glossary">bill of material (BOM)</Link> is useful is a
      company structure in which multiple business units produce various products
      with several of the same purchased components. This means that every business
      unit has a separate bill of material, but some components are used in every
      business unit. When each business unit wants to buy this component at a local
      supplier, you can make the item clustered. In this way, you can link a
      warehouse to the component involved in the <Link href="/baanerp/wh/glossary/glossary#000027" role="glossary">BOM line</Link>. If you also connect this
      warehouse
      to the corresponding local supplier in the <GUIRef href="/baanerp/tc/com/tccom4121s000" role="session">Ship-from Business Partner (tccom4121s000)</GUIRef> session, <GUIRef href="/baanerp/cp" role="package">Enterprise Planning</GUIRef> automatically selects the correct supplier during a planning run.</Paragraph>
