Setting up and using MPN items

Setting up MPN items

To set up manufacturer part numbers (MPNs):

  1. Select the Manufacturer Part Numbers check box in the Implemented Software Components (tccom0100s000) session.
  2. Select or clear the Multiple Items per MPN check box in the Procurement Parameters (tdpur0100m000) session.
  3. Select the MPN Item check box in the Items - Purchase (tdipu0101m000) session.
  4. Set the Item Cross Reference field to MPN in the Buy-from Business Partner (tccom4120s000) session.
  5. In the Manufacturers (tcmcs0160m000) session, specify the information about the manufacturers and assign a status to the manufacturers.
  6. In the Manufacturer Part Numbers (tdipu0145m000) session, specify manufacturer part numbers (MPNs) and link the MPNs to manufacturers. If the Multiple Items per MPN check box is cleared in the Procurement Parameters (tdpur0100m000) session, also use the Manufacturer Part Numbers (tdipu0145m000) session to link an item to a combination of MPN and manufacturer.
  7. If the Multiple Items per MPN check box is selected in the Procurement Parameters (tdpur0100m000) session, use the Items by MPN (tdipu0149m000) session to link items to a combination of MPN and manufacturer.
  8. If business partners cannot deliver all MPNs, specify which manufacturer part numbers 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. Through 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.

Using MPN items

In Procurement, MPN items can be used in these business objects:

  • Purchase requisitions
  • Requests for quotation (RFQs)
  • Purchase contracts
  • Purchase orders
  • Purchase schedules

Defaulting logic

This general defaulting logic applies to the MPN functionality in a business object:

  • If you select a manufacturer part number (MPN) by zooming from the Cross Reference Item field in the relevant session, the Item, Manufacturer, and Preferred Manufacturer Part Number are automatically defaulted from the Manufacturer Part Numbers (tdipu0145m000) or Items by MPN (tdipu0149m000) session.
  • If the Cross Reference Item field is not specified and you enter an MPN item in the Item field, the Preferred Manufacturer Part Number and Manufacturer are defaulted from the MPNs by Item - Business Partner (tdipu0148m000) session.
  • Generation of an MPN set is based on the data available in the MPNs by Item - Business Partner (tdipu0148m000) session.
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 Manufacturer Part Number from the RFQ Lines (tdpur1502m000) session is copied to the Manufacturer Part Number 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 Manufacturer Part Number in the RFQ 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 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 Set 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.
