Component documentation Inventory-Managed Manufacturer Part Number 

Purpose

Manufacturers can identify their parts uniquely and regulate the use of interchangeable parts in their parts catalogs. Inventory-Managed Manufacturer Part Number (IM-MPN) belongs to the component Manufacturer Part Number (IS-AD-MPN) and includes the following features:

·  Identification of parts using the manufacturer part number (MPN) issued by the manufacturer

The system finds, identifies, and displays these parts using the unique combination of manufacturer-specific details ‑ the Manufacturer Part Number (MPN) and the External Manufacturer. These parts are inventory-managed manufacturer parts, and are maintained with a complete material master record and their own stock.

·  Management of part interchangeability

The system recognizes parts from different manufacturers that have the same technical properties and are interchangeable in Purchasing, Inventory Management, MRP, and the Availability Check, as being interchangeable; these parts have their own stock. The management of part interchangeability includes:

¡  Inventory-managed manufacturer parts that are fully interchangeable with each other are grouped in a common class of interchangeable parts - a form-fit-function class (FFF class).

¡  You can group fully interchangeable parts of an FFF class in MPN-MRP sets subject to plant and planning area. The system treats these parts are treated as fully interchangeable parts in planning, inventory management, and the availability check.

¡  Restricted or one-way interchangeable parts cannot belong to the same FFF class. You use interchangeability codes to group these parts. Restricted interchangeability is available for all processes that support MPN. These processes are:

§  Sales order product selection

§  Sales rescheduling reports

§  ATP check for components in PM/CS order

§  General availability check

§  Goods receipt in transaction code MIGO

§  Stock overview

§  Stock transport order

§  Configuration control

Integration

The functions for Inventory-Managed Manufacturer Part Number are fully integrated with the components for Purchasing, Material Requirements Planning, and Sales and Distribution.

These functions supplement the functions for the non-inventory-managed Structure linkmanufacturer part number (MPN), which are available in the standard system as of Release 4.0. These functions contain a special material type (HERS), and an Approved Manufacturers’ Part List (AMPL). You can define different manufacturer parts as interchangeable by grouping their material masters in an internal material master.

Catalog Content Management (CCM) 1.0 supports the use of concatenated manufacturer part numbers.

Features

The functions include:

·  Master Data Maintenance

Maintenance and display of full and restricted interchangeability, as well as maintenance of MPN-MRP sets.

·  Input and Output Conversion of Material Numbers

The input conversion of material numbers allows you to enter the MPN and the external manufacturer instead of the SAP material number.
The output conversion ensures that the system outputs the MPN and external manufacturer in lists and on the screen instead of the SAP material number.

·  Interchangeable Manufacturer Parts in Purchasing

When processing quotations and purchase orders, you may have to exchange the part in the current process with another part, because you have received a quotation, notification, or delivery for an alternative part. The system supports you in changing and allocating the relevant order items so that the follow-on steps (in particular, goods receipt and invoice verification) refer to the part that was actually delivered.

·  Interchangeable Manufacturer Parts in MRP

There is a risk that inventory management on the MPN level could cause an excess of stock if the system does not take account of the interchangeability of parts. Therefore, in material requirements planning, the system takes account of the interchangeability of the parts to be procured, and ensures that a part is not ordered if another fully interchangeable part is in stock.

·  Interchangeable Manufacturer Parts in Inventory Management

The system holds different manufacturer parts in stock as separate parts. This gives you an overview of the manufacturer parts that are actually available, and allows the system to manage additional information, such as serial numbers or valuation. Cumulative analysis of interchangeable parts is also possible.

·  Interchangeable Manufacturer Parts in the Availability Check

If a part is not available, the availability check in PM orders and production orders also takes account of interchangeable parts.

·  Creation of subitems in stock transport orders. For more information, see Interchangeable Manufacturer Parts in the Availability Check and Interchangeability in Stock Transport Orders.

·  Goods movement using transaction code MIGO. You can interchange parts in the following:

¡  Goods issue for the stock transport order

¡  Goods receipt for the purchase order

¡  Goods issue for the reservation
