Retrieving purchase contracts

LN automatically links purchase schedules to contracts with the Active status. LN automatically links a normal contract to the purchase schedule. However, instead, you can link a special contract to the purchase schedule. To unlink the normal contract and link a special contract to the purchase schedule, click Change Contract in the Purchase Schedules (tdpur3110m000) session. As a result, the Selected Purchase Contract Lines (tdpur3512s000) 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 Terminate Purchase Schedule (tdpur3210m100) session. Now, you can link a special contract to the newly created purchase schedule.

When LN 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 nonreferenced schedules, LN uses the Generation Date in the Purchase Schedules (tdpur3110m000) session to determine which purchase contract price revision must be used from the Purchase Contract Prices (tdpur3103m000) session to retrieve prices and discounts. For referenced schedules, LN uses the Price Date Type field in the Pricing Parameters (tdpcg0100m000) session, which can be set to Order Date, System Date, or Delivery Date to determine which purchase contract price revision must be used.

LN automatically links purchase orders to contracts with the Active status. When a purchase order is created, LN 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.

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 Retrieval of terms and conditions.
