manufacturer part number (mpn)

Manufacturer Part Number (MPN)

Use

If you wish to influence the precise source or quality of materials, you can tell the vendor from whom you want toprocure a material which manufacturer the material is to be supplied by and the part number used by thatmanufacturer.

You can also tell your vendor exactly which of a manufacturer’s plants is to supply the material you wish to procure.

The manufacturer’s part number (MPN) and description, as well as the specific manufacturing plant (if applicable), areincluded in the data sent to the vendor with the purchase order.

Your vendor gets the steel bolts he supplies to you from the manufacturers Zenith Co. and Miller Corp.

However, you are not satisfied with the quality of the Zenith product. You wish to have the steel bolts thatare manufactured by Miller Corp. You advise your vendor of this in the purchase order by specifying themanufacturer and the MPN.

For procurement purposes, you can use the material or part number used by the manufacturer (MPN) alongside yourfirm’s own material number.

If you wish to check whether a certain Manufacturer Part may be ordered and used within your enterprise, you shouldmake use of the approved manufacturer parts list (AMPL). The latter indicates exactly which of a manufacturer’splants the materials included on the list are to be procured from.

For more information, refer to the section Approved Manufacturer Parts List.

If you wish to work with MPNs, you must set the Manufacturer part number indicator in Customizing for Logistics(General), (Basic Data, Logistics: Material Master ® Material ® Control Data ® Make Global Settings).

Create material master records

If you work with MPNs, the number of manufacturers of a manufactured part corresponding to one of your firm’s ownmaterials determines the number of material master records you have to create:

If there is just one MPN corresponding to one of your firm’s own materials, you can enter it and themanufacturer directly in the master record for your own material. In this case, you need not create an MPN

Material.If there are several MPN materials corresponding to one of your firm’s own materials, you must create MPNmaterial master records with the material type HERS. In the Purchasing view, enter the manufacturer partnumber, the manufacturer (this can be either a vendor master record or a manufacturer master record), andyour firm’s own, inventory-managed material.

The MPN material master records are assigned to your firm’s own material. Stocks are managed with respectto the firm’s own material.

0.8 cm steel bolts with a diameter of 0.5 cm are identified and stocked in your enterprise as the firm’sown, inventory-managed material RAW_S_08.

The manufacturer Meyer & Co. sells these bolts under the number 8001 (the manufacturer partnumber). This information is stored in the MPN material master record S_MEYER.

The manufacturer Smith Corp. supplies similar bolts under the number 4711. This information is storedin the MPN material master record S_SMITH.

The MPN material master records S_MEYER and S_ SMITH are assigned to the material master recordRAW_S_08.

Define manufacturer part profile

Manufacturer part profiles (MPN profiles) allow you to specify for each of your firm’s own materials the conditionsunder which the MPN material may be used in the procurement process.

Using the MPN profile, you can determine the following, for example:

Whether the MPN material has to be entered in the purchase order.Whether purchasing info records are created for the firm’s own material or for the MPN materials.Whether the PO text for the firm’s own material or the one for the MPN material is used.Whether the MPN material may be changed during the procurement process.Whether the system is to check the approved manufacturer parts list when an MPN material is entered.

You define the MPN profiles in Customizing for Purchasing under Material Master.

You enter the MPN profile in the master record for your firm’s own material (Purchasing view).

Create master records for manufacturers and manufacturer plants

If, during the process of procuring materials, you wish to have the option of choosing between several manufacturersof a material, or between several of a certain manufacturer’s plants, you must create separate master records for suchmanufacturers and for the relevant plants belonging to the latter.

The number of master records you will need to create for manufacturers, manufacturer plants, and vendors, dependson

Whether the vendor is also the manufacturerWhich of the plants belonging to a certain manufacturer you wish to procure materials from

Vendor is not the manufacturer

If the manufacturer is not a vendor (end supplier), you can store the manufacturer data in a manufacturermaster record with a minimum of data entry effort. You then assign the account group MNFR to this

manufacturer master record. If you wish to store an external ID for the manufacturer, enter it in the control data(External manufacturer field). This identification will appear in the purchase order.

Vendor is also the manufacturer

If the vendor is simultaneously the manufacturer, you can work with vendor master records. You must thenensure that a partner schema that takes the partner role HS into consideration is assigned to the account groupof the vendor master record. (In Customizing for Purchasing under Partner Determination ® Partner Settings inVendor Master Record ® Assign Partner Schemas to Account Groups). The manufacturer plants must thenhave the partner role HS in the vendor master record.

You wish to procure materials from certain specific manufacturer plants

If the manufacturer has several Manufacturer Plants, you can create a separate manufacturer master recordwith the account group MNFR for each of them. The manufacturer plants must have the partner role HS(manufacturer plant) in the manufacturer (vendor) master record.

The following graphic shows which partner roles you have to maintain in the master records for the vendor,manufacturer, and manufacturer plant:
