      <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>

         <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="manual">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, ERP Enterprise takes into account one of the following
		  bills to carry out component CTP checks:</Paragraph>

         </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 ERP Enterprise checks lower-level components as well.</Paragraph>

            <Paragraph>The component CTP check ignores the <Link href="/baanerp/tc/glossary/glossary#000455" role="glossary">specification</Link>, regardless of the value of the <Link href="/baanerp/ti/bom/tibom1110m000#tibom010.hppr" role="formfield">Demand Peg Propagation</Link> field in the <GUIRef href="/baanerp/ti/bom/tibom1110m000" role="session">Bill of Material (tibom1110m000)</GUIRef> session.

            <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>
