| # To set up and use MPN items To set up MPN items To set up manufacturer part number (MPN) items, take the following steps: Select the Manufacturer Part Numbers Implemented check box in the Implemented Software Components (tccom0100s000) session. Select the MPN Item check box in the Items - Purchase (tdipu0101m000) session. Set the Item Cross Reference field to MPN in the Buy-from Business Partners (tccom4120s000) session. In the Manufacturers (tcmcs0160m000) session, enter the information about the manufacturer and assign a status to the manufacturer. In the Manufacturer Part Numbers (tdipu0145m000) session, define manufacturer part numbers (MPNs) and link the MPNs to an item and manufacturer.You can also use this session to link a preferred MPN to an item, to enter effective and expiry dates or to assign a status to the MPN. If business partners cannot deliver all MPNs, define which manufacturer part numbers (MPNs) can be delivered by which business partners for an item in the MPNs by Item - Business Partner (tdipu0148m000) session. You can also use this session to link a preferred MPN to an item and business partner. By means of the Import MPNs by Item - Business Partner (tdipu0248m000) session, you can link all MPNs for an item to the selected business partner. However, if no MPNs are specified for an item-business partner combination, the business partner can deliver all MPNs of an item. Note You can use the Global update MPN Details (tdipu0245m000) session to globally update the status and effectivity period of MPNs. To use MPN items Purchase requisitions If you enter a manufacturer part number (MPN) in the Cross Reference Item field of the Requisition - Line Details (tdpur2102s000) session, the Item, Manufacturer, and Preferred Manufacturer Part Number are automatically defaulted from the Manufacturer Part Numbers (tdipu0145m000) session. The MPN can either have the status Approved or For Approval on the Requisition Date. Blocked MPNs are not allowed. Only if a Buy-from Business Partner is entered in the Requisition - Line Details (tdpur2102s000) session, ERP LN checks whether the business partner is allowed to deliver the MPN in the MPNs by Item - Business Partner (tdipu0148m000) session. If you convert a requisition to an order, the MPN must have the Approved status. ERP 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) If you enter a manufacturer part number (MPN) in the Cross Reference Item field of the Purchase Request for Quotation Lines (tdpur1502m000) session, the Item, Manufacturer, and Preferred Manufacturer Part Number are automatically defaulted from the Manufacturer Part Numbers (tdipu0145m000) session. The MPN must have the status Approved or For Approval on the RFQ Date. The Preferred Manufacturer Part Number from the Purchase Request for Quotation Lines (tdpur1502m000) session is copied to the Preferred MPN field of the Buy-from BP - Quotations (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. As a result, you must select another business partner, or you must change the Preferred Manufacturer Part Number in the Purchase Request for Quotation Lines (tdpur1502m000) session. If you convert an RFQ to a purchase order or to a contract and the MPN has the Approved status, ERP 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 master data. Purchase contracts If you enter a manufacturer part number (MPN) in the Cross Reference Item field of the Purchase Contract Lines (tdpur3101m000) session, the Item, Manufacturer, and Preferred Manufacturer Part Number are automatically defaulted from the Manufacturer Part Numbers (tdipu0145m000) session. The MPN must have the status Approved on the Contract Date. 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 If you enter a manufacturer part number (MPN) in the Cross Reference Item field of the Purchase Order Lines (tdpur4101m000) session, the Item, Manufacturer, and Preferred Manufacturer Part Number are automatically defaulted from the Manufacturer Part Numbers (tdipu0145m000) session. The MPN must have the status Approved on the Order Date. When the purchase order line is saved, ERP LN automatically links an MPN set to the purchase order line (detail). If 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 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. If an item is received in the Warehouse Receipts (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 enter a manufacturer part number (MPN) on the schedule header. Although the scheduled item appears on the schedule header, the MPN must be entered on the schedule line. If you enter an MPN in the Preferred Manufacturer Part Number field of the Purchase Schedule - Lines (tdpur3111m000) session, the Manufacturer is automatically defaulted from the Manufacturer Part Numbers (tdipu0145m000) session. The MPN must have the status Approved on the requirement date, which is the planned delivery date. When the purchase schedule line is saved, ERP LN automatically links an MPN set to the purchase schedule line. If 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. If an item is received in the Warehouse Receipts (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 In addition to a large number of other fields, 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 details, refer to To cluster purchase schedule lines.
