SAP MM tips 5 – manufacturer part number


In SAP MM you define materials which are used inside a company. These can be raw materials, semi finished materials, finished materials, packing materials and many other types of materials. The material definitions are company specific and the same material names and numbers will be different if they are used for any other company.

When raw materials are procured from vendors, the manufacturer usages its own definition of materials when they procure. the vendors are forced to use this definition of materials.

In many cases, it is not possible for vendors to use this definition of materials. They have their own material definitions. In many cases, the vendor is actually a trader who procures materials from some other manufacturer and supplies materials to other manufacturers. This scenario results in a situation where there are 2 names for the same material. In such cases, how the vendor definition of materials and manufacturers definition of the same materials can be paired so that vendors can supply materials to the manufacturer without the confusion of material names?

In SAP MM there is a facility to pair these 2 types of definitions of the same material. A manufacturer part number (MPN) is created for each material number used by the manufacturer. This manufacturer part number is paired to the material number used by the manufacturer. Once this pairing is done then on the PO, the manufacturer puts the MPN number. After good receipt, the same material is stored with the manufacturer internal number.

There are some limitations as to how the MPN number and internal material number can be used in the SAP system. For instance, it is possible to create Info Record for both MPN number as well as the internal material number for standard Info Record category. But it is not possible to create Info Record for MPN number in case of consignment.
