         <ListIntro>ERP Enterprise provides extensive functionality to support order promising. The following
		  concepts are central to order promising:</ListIntro>
         <ListItem>An item’s ATP is the quantity that is available for customers
		  either immediately, or on a specific time in the future.</ListItem>
         <ListItem>An item’s Capable to Promise (CTP) quantity, is the quantity
		  that is available in addition to the ATP, based on the spare production
		  capacity of your production facility.</ListItem>
      </List>
      <Paragraph>Available to Promise (ATP) and Capable to Promise (CTP) support
		is important functionality for a reliable order acceptance procedure. To
		prevent over-promising of products to customers, the system may need to check
		on available inventory of finished goods, available sub-assemblies and
		components, and available production capacity.</Paragraph>
      <List>
         <ListIntro>You can use ATP checks in two ways:</ListIntro>
         <ListItem>Online The sales employee performs an ATP check for one sales
		  order during the sales-order-entry procedure or the sales-quotation-entry
		  procedure.</ListItem>
         <ListItem>Offline The customer does not immediately receive a delivery
		  date from the sales employee. Instead, you prioritize multiple orders and
		  promise dates later.</ListItem>
      </List>
      <Paragraph>To support both situations, you can use the <GUIRef href="/baanerp/td/sls/tdsls4899m000" role="session">ATP Handling (tdsls4899m000)</GUIRef> session during sales order entry, and also offline as
		a separate session.</Paragraph>

      <SectionTitle>Parameters</SectionTitle>
      <Paragraph>The following parameters influence the way that ERP Enterprise performs ATP checks
		and CTP checks. You can set these parameters in the <GUIRef href="/baanerp/cp/rpd/cprpd0100m000" role="session">Planning Parameters (cprpd0100m000)</GUIRef> session.</Paragraph>
      <Paragraph>If the <GUIRef href="/baanerp/cp/rpd/cprpd0100m000#cprpd000.onat" role="manual">Online ATP Update in EP</GUIRef> check box is selected, every
		time you save a sales order line, ERP Enterprise immediately updates the sales-order reservations and CTP
		reservations in the Enterprise Planning package and recalculates the ATP
		quantities. This ensures that the next sales order line is checked against
		updated ATP quantities. This prevents the sales clerk from promising the same
		product ATP quantities to different customers.</Paragraph>
      <List>
         <ListIntro>If the <GUIRef href="/baanerp/cp/rpd/cprpd0100m000#cprpd000.atpq" role="manual">CTP Check for Sales</GUIRef> check box is selected, ERP Enterprise responds in these ways:</ListIntro>
         <ListItem>If you insert the ordered quantity on a sales order line, ERP Enterprise performs an
		  automatic ATP check. If the sales order line quantity exceeds the cumulative
		  ATP quantity, a screen appears that includes an <GUIRef href="/baanerp/td/sls/tdsls4899m000" role="session">ATP Handling (tdsls4899m000)</GUIRef> option.</ListItem>
         <ListItem>If you save a sales order line, and the ordered quantity
		  exceeds the cumulative ATP, ERP Enterprise blocks the sales order line. You cannot save the sales order line
		  if the ordered quantity is too high.</ListItem>
