	<GeneralSection><Paragraph>Extended <Link href="/baanerp/cp/glossary/glossary#000029" role="glossary">CTP</Link> checks are used to explore the possibility of producing an extra quantity of an item, in addition to the existing planning. Extended CTP checks come into play if the standard <Link href="/baanerp/cp/glossary/glossary#000030" role="glossary">ATP</Link> of a plan item is insufficient to cover a particular demand.</Paragraph>
		<List><ListIntro>In <GUIRef href="/baanerp/cp" role="package">Enterprise Planning</GUIRef> there are two types of extended CTP checks:</ListIntro>
			<ListItem><Link href="/baanerp/cp/glossary/glossary#000035" role="glossary">Component CTP check</Link>
			</ListItem>
			<ListItem><Link href="/baanerp/cp/glossary/glossary#000034" role="glossary">Capacity CTP check</Link>
			</ListItem>
		</List>
		<Paragraph>You can enable or disable these checks in the <GUIRef href="/baanerp/cp/rpd/cprpd1100m000" role="session">Items - Planning (cprpd1100m000)</GUIRef> session. In the <GUIRef href="/baanerp/td/sls/tdsls4899m000" role="session">ATP Handling (tdsls4899m000)</GUIRef> session, you can temporarily disable particular checks.</Paragraph>
		<GeneralSection><SectionTitle>Component CTP</SectionTitle>
			<Paragraph>A component CTP check for a plan item involves a full CTP check of the components of an item for which you selected the <GUIRef href="/baanerp/cp/rpd/cprpd1100m000#cprpd100.cria" role="formfield">Critical in CTP</GUIRef> check box in the <GUIRef href="/baanerp/cp/rpd/cprpd1100m000" role="session">Items - Planning (cprpd1100m000)</GUIRef> session.</Paragraph>
			<Paragraph>Depending on the situation and on the item type, SSA ERP takes into account one of the following bills to carry out component CTP checks:</Paragraph>
			<List><ListItem><Link href="/baanerp/ti/glossary/glossary#000081" role="glossary">Bill of critical material (BCM)</Link>: if the item has an <Link href="/baanerp/cp/glossary/glossary#000019" role="glossary">item master plan</Link>.</ListItem>
				<ListItem><Link href="/baanerp/tp/glossary/glossary#000323" role="glossary">Bill of material (BOM)</Link>: if <List><ListItem>SSA ERP carries out the component CTP check in the <Link href="/baanerp/cp/glossary/glossary#000065" role="glossary">order horizon</Link>.</ListItem>
						<ListItem>The item is not a <Link href="/baanerp/ti/glossary/glossary#GeneriItem.ti" role="glossary">generic item</Link>.</ListItem>
					</List>
				</ListItem>
				<ListItem><Link href="/baanerp/cf/glossary/glossary#000020" role="glossary">Generic BOM</Link>: if the item is a generic item. SSA ERP first configures the ordered item by means of the generic BOM, and then performs a component CTP check by taking into account the components of the customized BOM.</ListItem>
			</List>
			<Paragraph>For each CTP-critical component, a full CTP check is carried out. This check can consist of various types of ATP and CTP checks, based on the settings in the <GUIRef href="/baanerp/cp/rpd/cprpd1100m000" role="session">Items - Planning (cprpd1100m000)</GUIRef> session. Note that this can result in a multilevel component check, in which SSA ERP checks lower-level components as well.</Paragraph>
		</GeneralSection>
		<GeneralSection><SectionTitle>Capacity CTP</SectionTitle>
			<Paragraph>A capacity CTP check for a plan item involves a capacity check on each resource in the item's <Link href="/baanerp/ti/glossary/glossary#BillOfCritic.ti" role="glossary">bill of critical capacities</Link> that is defined as <Link href="/baanerp/cp/glossary/glossary#000039" role="glossary">critical in CTP</Link>.</Paragraph>
		</GeneralSection>
		<GeneralSection><SectionTitle>Combinations of checks</SectionTitle>
			<List><ListIntro>Extended CTP checks are cumulative in nature:</ListIntro>
				<ListItem>For items, the cumulative availability in a certain plan period (corrected for future deficiencies) is checked.</ListItem>
				<ListItem>For resources, the capacity up to and including a certain plan period (corrected for future deficiencies) is checked.</ListItem>
			</List>
			<Paragraph>Because of this cumulative nature, some caution is called for when component and capacity checks are both used for an item. If both checks succeed, this does not necessarily mean that the availability of components and capacity will exactly match in terms of time. After all, some of the available capacity can fall in a plan period in which the necessary components are not yet available.</Paragraph>
