      <Paragraph>ERP Enterprise automatically links <Link href="/baanerp/td/glossary/glossary#000000000000011" role="glossary">purchase schedules</Link> to
		contracts with the <GUIRef href="/baanerp/tc/domains/icap#active" role="option">Active</GUIRef> status. ERP Enterprise automatically links a <Link href="/baanerp/td/glossary/glossary#NormalContra_td" role="glossary"
               Update="No">normal contract</Link> to the purchase schedule. However, instead, you can link a <Link href="/baanerp/td/glossary/glossary#SpeciaContra_td" role="glossary">special contract</Link> to the
		purchase schedule. To unlink the normal contract and link a special contract to
		the purchase schedule, click <GUIRef href="/baanerp/td/pur/tdpur3110m000#change.contract" role="command">Change Contract</GUIRef> in the <GUIRef href="/baanerp/td/pur/tdpur3110m000" role="session">Purchase Schedules (tdpur3110m000)</GUIRef> session. As a result, the <GUIRef href="/baanerp/td/pur/tdpur3512s000" role="session">Selected Purchase Contract Lines (tdpur3512s000)</GUIRef> session starts from which you can
		select a special contract. However, you can replace the normal contract by a
		special contract only if no receipts are booked yet for the purchase schedule.
		If receipts are already booked, you must terminate the existing purchase
		schedule and create a new purchase schedule in the <GUIRef href="/baanerp/td/pur/tdpur3210m100" role="session">Terminate Purchase Schedule (tdpur3210m100)</GUIRef> session. Now, you can link a special contract
		to the newly created purchase schedule.</Paragraph>
      <Paragraph>When ERP Enterprise links a contract to the purchase schedule, the schedule header is loaded with
		the default values of the linked contract. Specific addresses, as well as
		contract terms and prices and discounts, are adopted on the schedule level. For
		non-referenced schedules, ERP Enterprise uses the <GUIRef href="/baanerp/td/pur/tdpur3110m000#tdpur310.gdat" role="manual">Generation Date</GUIRef> in the <GUIRef href="/baanerp/td/pur/tdpur3110m000" role="session">Purchase Schedules (tdpur3110m000)</GUIRef> session to determine which <Link href="/baanerp/td/glossary/glossary#000332" role="glossary">purchase contract price revision</Link> must be used from the <Link href="/baanerp/td/pur/tdpur3103m000" role="session">Purchase Contract Price Revisions (tdpur3103m000)</Link> session to retrieve prices and
		discounts. For referenced schedules, ERP Enterprise uses the <GUIRef href="/baanerp/td/pcg/tdpcg0100m000#tdpcg000.ppdt" role="manual">Purchase Price Date Type</GUIRef> field in the <GUIRef href="/baanerp/td/pcg/tdpcg0100m000" role="session">Pricing Parameters (tdpcg0100m000)</GUIRef> session, which can be set to <GUIRef href="/baanerp/td/domains/pur.pric#order.date" role="option">Order Date</GUIRef>, <GUIRef href="/baanerp/td/domains/pur.pric#system.date" role="option">System Date</GUIRef>, or <GUIRef href="/baanerp/td/domains/pur.pric#delivery.date" role="option">Delivery Date</GUIRef> to determine which purchase contract price revision must be
		used.</Paragraph>

         <Paragraph>For schedules lines with a <Link href="/baanerp/tc/glossary/glossary#000441" role="glossary">configured item</Link>, the <Link href="/baanerp/td/pur/tdpur3101m000#tdpur301.obpr" role="formfield">Option Based Pricing</Link> check box is automatically
		  selected in the <GUIRef href="/baanerp/td/pur/tdpur3101m000" role="session">Purchase Contract Lines (tdpur3101m000)</GUIRef> session. For more information, refer to <Link href="/baanerp/td/onlinemanual/000310" role="manual">Configured items on purchase schedules</Link>.</Paragraph>

      <Paragraph>ERP Enterprise automatically links <Link href="/baanerp/td/glossary/glossary#PurchaOrders_td" role="glossary"
               Update="No">purchase orders</Link> to contracts with the <GUIRef href="/baanerp/tc/domains/icap#active" role="option">Active</GUIRef> status. When a purchase order is created, ERP Enterprise first searches for
		special contracts and then for normal contracts. If more special contracts are
		valid for the buy-from business partner/item(group)/date, a selection screen
		appears from which you must select a contract.</Paragraph>
      <Paragraph>To retrieve terms and conditions from an active contract for an
		order line, the contract need not be linked to the order line. As a result, the
		contract number is only filled on the order line if an active contract line is
		linked to the order line. For more information, refer to <Link href="/baanerp/tc/onlinemanual/000509" role="manual">Retrieving terms and conditions</Link>.</Paragraph>
