	<HelpTopic><AimSection><Paragraph>Use this session to define a <Link href="/baanerp/ti/glossary/glossary#000081" role="glossary">bill of critical material (BCM)</Link>. A BCM indicates the components that are regarded as critical during the production process of an item. The BCM is a kind of summary of the production <Link href="/baanerp/ti/glossary/glossary#BillOfMateri.ti" role="glossary">bill of material (BOM)</Link> that contains only the important components, that is, the relationships between a <Link href="/baanerp/ti/glossary/glossary#PlanItems.ti" role="glossary">plan item</Link> and its critical items.</Paragraph>
		</AimSection>
		<GeneralSection><Paragraph>A BCM allows you to plan for bottleneck items in the production process. Typical examples of bottleneck items are components with long lead times, and subassemblies with a high capacity load for the internal or external production systems.</Paragraph>
			<Paragraph>An important feature in <GUIRef href="/baanerp/cp" role="package">Enterprise Planning</GUIRef> is the <GUIRef href="/baanerp/cp/rpd/cprpd3120m000#cprpd320.cwar" role="formfield">Warehouse</GUIRef> field in the <GUIRef href="/baanerp/cp/rpd/cprpd3120m000" role="session">Bill of Critical Materials (cprpd3120m000)</GUIRef> session. You must fill this field to avoid that <GUIRef href="/baanerp/cp" role="package">Enterprise Planning</GUIRef> explodes the dependent demand during a master-plan simulation to a different warehouse than it does during an order-planning run. If a warehouse is specified on the <Link href="/baanerp/wh/glossary/glossary#000027" role="glossary">BOM line</Link> in the <GUIRef href="/baanerp/ti/bom/tibom1110m000" role="session">Bill of Material (tibom1110m000)</GUIRef> session, SSA ERP uses this warehouse to fill the <GUIRef href="/baanerp/cp/rpd/cprpd3120m000#cprpd320.cwar" role="formfield">Warehouse</GUIRef> field. If no warehouse is specified on the <Link href="/baanerp/wh/glossary/glossary#000027" role="glossary">BOM line</Link>, SSA ERP uses the warehouse you specified in the <GUIRef href="/baanerp/tc/ibd/tcibd2500m000" role="session">Items - Ordering (tcibd2500m000)</GUIRef> session for the item. You can also fill the <GUIRef href="/baanerp/cp/rpd/cprpd3120m000#cprpd320.cwar" role="formfield">Warehouse</GUIRef> field manually.</Paragraph>
			<Paragraph>You can either define the BCM manually in this session, or click the Generate Bill of Critical Materials option on the Specific menu to let SSA ERP generate the BCM automatically. In the latter case, SSA ERP explodes the production BOM to the lowest <Link href="/baanerp/ti/glossary/glossary#CriticBOMLev.ti" role="glossary">critical BOM level</Link> on which a critical item can be found. For more information, see <Link href="/baanerp/ti/onlinemanual/000182" role="manual">Critical items</Link>.</Paragraph>

				<Paragraph>If SSA ERP makes a bill of critical material, it takes the effective and expiry dates of the items, that is, the item validity, into account.</Paragraph>

				<Paragraph>SSA ERP takes into account the parent/child relation when it generates <Link href="/baanerp/cp/glossary/glossary#000074" role="glossary">dependent demand</Link> for critical components. When you carry out the <GUIRef href="/baanerp/cp/rmp/cprmp1202m000" role="session">Generate Master Planning (cprmp1202m000)</GUIRef> session, Enterprise Planning performs the following steps to compute dependent demand for critical components:</Paragraph>
				<ProcedureList><ListItem>SSA ERP offsets the <Link href="/baanerp/ti/glossary/glossary#LeadTime.ti" role="glossary">lead time</Link> of the parent item to the <Link href="/baanerp/cp/glossary/glossary#000109" role="glossary">plan periods</Link>, and divides the forecasted demand to the plan periods.</ListItem>
					<ListItem>SSA ERP rounds the forecasted quantities that it found in step one according to the <Link href="/baanerp/tc/glossary/glossary#UnitSet.tc" role="glossary">unit set</Link> that you defined for the item in the <GUIRef href="/baanerp/tc/ibd/tcibd0501m000" role="session">Items - General (tcibd0501m000)</GUIRef> session.</ListItem>
					<ListItem>During the next step, SSA ERP multiplies each BCM quantity by the total of the parent item for each plan period.</ListItem>
					<ListItem>SSA ERP rounds the critical components to the unit set that you defined for them in the <GUIRef href="/baanerp/tc/ibd/tcibd0501m000" role="session">Items - General (tcibd0501m000)</GUIRef> session.</ListItem>
				</ProcedureList>
				<Paragraph>The major advantage of this offsetting method is that SSA ERP always plans a multiple of the BCM quantity for each plan period, so that you do not have to wait to produce the parent item until the <Link href="/baanerp/cp/glossary/glossary#000018" role="glossary">production plan</Link> for all the periods over which the dependent demand is spread, is executed.</Paragraph>
			</SimpleSection>
