Setting up and using MPN itemsSetting up MPN items To set up manufacturer part numbers (MPNs):
Note You can use the Global update MPN Details (tdipu0245m000) session to globally update the status and effectivity period of MPNs. Using MPN items In Procurement, MPN items can be used in these business objects:
Defaulting logic This general defaulting logic applies to the MPN functionality in a business object:
Purchase requisitions If a Buy-from Business Partner is specified in the Purchase Requisition Lines (tdpur2502m000) session, LN checks whether the business partner is allowed to deliver the MPN in the MPNs by Item - Business Partner (tdipu0148m000) session. When you convert a requisition to an order, the status of the MPN must be Approved. LN copies the Preferred Manufacturer Part Number to the purchase order and generates an MPN set that is linked to the purchase order. You can always convert a requisition to an RFQ. Requests for quotation (RFQs) When you link a business partner to an RFQ, the Preferred Manufacturer Part Number from the Request for Quotation Lines (tdpur1502m000) session is copied to the Preferred MPN field in the RFQ Responses (tdpur1506m000) session. However, if the preferred MPN from the RFQ line is not allowed for a business partner, the business partner cannot be linked to the RFQ. Therefore, you must select another business partner or you must change the Preferred Manufacturer Part Number in the Request for Quotation Lines (tdpur1502m000) session. When you convert an RFQ to a purchase order or a contract and the status of the MPN is Approved, LN copies the Preferred Manufacturer Part Number to the purchase order or purchase contract and generates an MPN set for the purchase order. If the item is an MPN item but no MPN is filled on the RFQ, the MPN and manufacturer are defaulted from the Items - Purchase (tdipu0101m000) session. Purchase contracts Business partners are allowed to supply alternative MPNs, but always against the original contract price. If a purchase order is generated from a delivery contract, the MPN is used as a default. However, defaulting is not applicable if a purchase contract is linked to a purchase order. Purchase orders When the purchase order line with an MPN item is saved, LN automatically links an MPN set to the purchase order line (detail). When you click the MPN Sets button, the Purchase Order Line MPN Sets (tdpur4601m100) session is started in which you can view and maintain the MPN set that is linked to the purchase order line (detail). If you change the Preferred Manufacturer Part Number on the purchase order line and this MPN is not part of the MPN set, a question is asked if you want to add this MPN to the MPNs by Item - Business Partner (tdipu0148m000) session and if you want to make it the preferred MPN in the MPNs by Item - Business Partner (tdipu0148m000) session. If the preferred MPN is changed or deleted in the Purchase Order Line MPN Sets (tdpur4601m100) session, the preferred MPN on the purchase order line (detail) is also changed or deleted. You cannot maintain the MPN set after receipts are executed for the purchase order line. When an item is received in the Warehouse Receipt (whinh3512m000) session or in the Purchase Receipts (tdpur4106m000) session, the actual MPN that appears in these receipt sessions must belong to the MPN set that is linked to the purchase order line. After receipts are executed for the purchase order line, the actual MPN is transferred to the Purchase Actual Receipt History (tdpur4556m000) session. Purchase schedules Because MPNs change regularly, you cannot specify a manufacturer part number (MPN) on the schedule header. Although the scheduled item appears on the schedule header, the MPN must be specified on the schedule line. When the purchase schedule line with an MPN item is saved, LN automatically links an MPN set to the purchase schedule line. When you click the MPN Sets button, the Purchase Schedule Line MPN Sets (tdpur3611m100) session is started in which you can view and maintain the MPN set that is linked to the purchase schedule line. If the preferred MPN is changed or deleted in the Purchase Schedule Line MPN Sets (tdpur3611m100) session, the preferred MPN on the purchase schedule line is also changed or deleted. You cannot maintain the MPN set after receipts are executed for the purchase schedule line. When an item is received in the Warehouse Receipt (whinh3512m000) session or in the Purchase Schedule - Receipts (tdpur3115m200) session, the actual MPN that appears in these receipt sessions must belong to the MPN set that is linked to the purchase schedule line. After receipts are confirmed for the purchase schedule line, the actual MPN is transferred to the Purchase Actual Receipt History (tdpur4556m000) session. Note The Preferred Manufacturer Part Number, Manufacturer, and the contents of the MPN sets that are linked to the purchase schedule lines must match before schedule lines can be clustered in the same purchase release line detail in the Purchase Release Line - Details (tdpur3522m000) session. For more information, refer to Clustering purchase schedule lines.
