      <Paragraph>The CTP settings in the <GUIRef href="/baanerp/cp/rpd/cprpd1100m000" role="session">Items - Planning (cprpd1100m000)</GUIRef> session determine which checks LN actually carries out.

         <Paragraph>If <Link href="/baanerp/cp/glossary/glossary#000032" role="glossary">family CTP</Link> is enabled for
		  the plan item, LN checks
		  if the date for which the CTP must be computed falls within the <Link href="/baanerp/cp/glossary/glossary#000033" role="glossary">family CTP horizon</Link>:</Paragraph>

            <ListItem>If the date falls

         <SectionTitle>Step 2: ATP check</SectionTitle>

      <GeneralSection>
         <SectionTitle>Step 3: Extended CTP check</SectionTitle>
         <List>
            <ListIntro>If the ATP found in Step 2 is insufficient, LN can carry out an
			 extended CTP check, depending on the CTP settings for the plan item. This check
			 can be:</ListIntro>
            <ListItem>A <Link href="/baanerp/cp/glossary/glossary#000035" role="glossary">component CTP check</Link>.</ListItem>

         <SectionTitle>Step 4: Channel ATP check</SectionTitle>
         <Paragraph>If channel ATP is
		  enabled for a plan item and the item is going to be sold to a business partner
		  in a particular channel, LN also carries out a channel ATP check. The
		  resulting value is compared with the result of Steps 2 and 3 (the regular
		  ATP/CTP check), and the smallest of these values is used as the final CTP
		  value.</Paragraph>

         <Paragraph>Item A is produced on (critical) resource R, and uses item C

		  A:</Paragraph>
         <ProcedureList>
            <ListItem> LN checks the ATP of the A item, which is a standard ATP check. The requested
			 quantity cannot be covered entirely by the ATP value of item A.</ListItem>
            <ListItem>LN checks the capacity CTP of resource R to see if it can fill the shortage of
			 item A by increasing the production.</ListItem>
            <ListItem>LN checks the ATP of component item C, to see if item A can be produced.

			 piece) must be manufactured in addition to the production plan.</ListItem>
            <ListItem>The production of 300
			 cabinets requires a capacity of 30 hours in week number 5. The available
			 capacity is only 25 hrs. (The available capacity is cumulated from the present
			 date up to week 5). You can produce only 250 cabinets in time, provided that
			 the critical components are available. The components and the capacity can be
			 available, but the responsible planner might be required to reshuffle orders
			 that also require capacity of the resource involved to make the capacity
			 available on the required moment.</ListItem>
            <ListItem>The production of 300
			 cabinets requires 300 sheets of metal to be available in week 5. The table
			 shows that this is not a problem.</ListItem>
         </List>
         <Paragraph>The conclusion of the
		  CTP check is: You are capable of promising 400 (150 + 250) filing cabinets in
