Track Multiple Manufacturer Part Numbers Effectively
Using Manufacturer Part Number Management
y Suresh Veeraraghavan, Manager, Capgemini (June 2010) • June 3, 2010
Learn how you can set up manufacturer part numbers (MPNs) to manage your multiple vendor part
numbers efficiently. These are the configuration steps, tips and tricks, and common pitfalls you
need to watch out for when implementing this functionality.
Key Concept
A manufacturer part number (MPN) is a part number by which a material provided by a
manufacturer is identified. A company can use the same part number for parts supplied by multiple
manufacturers. MPN is a useful functionality to help in managing and tracking these parts.
ypically in any industry, parts are manufactured at the manufacturer’s plant and then supplied to the
endor. The vendor in turn distributes them to the end company that consumes them. In this supply
ain there can be several manufacturers and several vendors.
endors and manufacturers use several part numbers to represent like materials, thereby making it
fficult for companies that buy from them to track these parts. Figure 1 explains the challenge.
Figure 1 Example of multiple MPNs supplied by manufacturers (MPN A, MPN B, MPN C)
anufacturers A, B, and C all provide the same part, but the part numbers differ: MPN A, MPN B, and
PN C. The company that procures these part numbers from these manufacturers uses a single inventory
art number to represent them. This presents a challenge to the company as it now has to manage and
ack these various manufacturer part numbers. To overcome this challenge, SAP has a useful
nctionality called manufacturer part number (MPN). The following four scenarios are examples of how
PNs can address the challenge.

the simplest scenario, each inventory part number of the company has only one MPN. The following
eps explain how to set up scenario 1:
ep 1. Activate the global setting for MPN. Follow menu path Logistics (General) ( Material Master >
asic Settings > Make Global Settings (Figure 2). Activate MPN Manager by checking the Manufacturer
art no. check box.
Figure 2 Activate MPN management
nabling the global setting for MPN shows additional fields on the material master – Manufacturer part
o., Manufacturer Profile (Mfr. Part Profile), and Manufacturer (Manufact) in Figure 3.
ep 2. In the inventory part number (Material number 544), the manufacturer’s part number is
aintained as a free text field in the purchasing view (Mfr Part Number ABC).
he manufacturer ABC in the Mfr Part Number field is assigned to 544, which is the inventory part
umber in the Material field (Figure 3).
Figure 3Mfr Part Number ABC assigned to Material 544 (which is the inventory part number)
his scenario does not require any configuration. Once the MPN is assigned to the inventory part number,
flows into the purchase order and the follow-on documents.
cenario 2: The Vendor Is the Same as the Manufacturer
this scenario the vendor is the same as manufacturer. Take the following steps to enable this it:
ep 1. Activate the global setting for the MPN as done in scenario 1.
ep 2. Set up the MPN profile. The MPN profile controls how the MPN works (Figure 4). Several key

dicators are associated with the profile.
Figure 4 Define the manufacturing profile
he fields in Figure 4 are as follows:
Order Text for MPN Material controls the text that defaults on the purchase order from the
manufacturing part number.
MPN Mandatory controls whether the MPN is mandatory on the purchase order. If this indicator
check box is checked, then the purchase order must have an MPN on it.
Change in MPN controls if the MPN can be changed on the purchase order. If the indicator check
box is checked, the MPN can be changed.
QM Processing for MPN is not activated for this scenario. Another scenario describes how this
indicator works.
AMPL (approved management part list) Management controls if the approved manufacturing part
list is maintained or not and from where the MPN is procured (Figure 5). The inventory part
number (Int. material no. 544) can be linked to the manufacturer (Manufactur 198) and the
manufactured parts (MPN Materials “MNFR_A” and “MNFR_B”. The validity dates ( Valid from and
Valid to) can be defined for the manufacturer and the MPN. If for any reason the manufacturer
needs to be blocked, this can be done as well (Bloc 001), and then this MPN is not proposed as a
source.
Updating Logistics Information System (LIS) controls if the LIS is updated or not. LIS can report
by MPN if this indicator is switched on. Entering “1” in Checkg Rule: Manuf ensures a check is
made to see if the manufacturer is valid by enabling a special partner function HS. HS is the value
used by SAP to identify a manufacturer as a partner (Partner functions are used to identify the
various business partners a company is doing business with. Each partner is identified by a
partner function. For example, VN partner function is the value used to identify a vendor and GS is
the value used to identify a goods vendor. Similarly, HS is used to identify a manufacturing plant.

Figure 5Approved MPN profile defined
ep 3. Once the configuration setup is completed, the MPN profile defined in step 2 is manually assigned
the inventory managed parts (Figure 6).
Figure 6 Mfr Part Profile Z000 is assigned to inventory managed part
ep 4. Assign the Manufacturing plant partner (MP) function to the vendor manually ( Figure 7). MP is a
ecial partner function which identifies the manufacturing plant. In this case, the manufacturer and the
endor are the same, so the number for the manufacturer and vendor are the same. There is no need to
eate separate manufacturer records.
Figure 7Manufacturer vendor partner function MP assigned to vendor
ep 5. Create the MPNs. Material type HERS is used for this purpose. HERS has been created
ecifically to represent MPNs. It has two views, namely purchasing and basic data. Assign the inventory
anaged part identified by Int. material number 544 to the Mfr. Part Number Manufacturer_A as shown
Figure 8. If there are multiple MPNs, the inventory part number is assigned to each of the MPNs
eated.

Figure 8 Assign Inventory part number (Int. material number) to the Mfr Part Number
(MANUFACTURER_A)
ep 6. Set up the purchase information record (PIR) for the MPN. This is set up like any other PIR. Use
ansaction code ME11 to set up the PIR for the MPN and vendor.
ep 7. Create the approved manufacturer parts list (as shown in Figure 5). Set up the approved
anufacturer parts list by associating the MPN materials to the inventory managed part (Int Material
o.).
cenario 3: Vendor Is Not the Same as the Manufacturer
his scenario represents the case in which the vendors and the manufacturers are different. The setup
llows the same steps as explained in the previous scenario with one key difference: As the manufacturer
nd vendor are different the MPN has to be created as vendor records as well. A special account group
lled MNFR is used to create these records manually. If there are multiple manufacturing plants for the
anufacturer each plant is created as a manufacturer.
cenario 4: MPN with SAP Quality Management Activation
some industries such as bio-tech, SAP Quality Management (SAP QM) is activated to perform
spections and pass or fail inspection lots. The MPN can be used in conjunction with SAP QM. The
llowing steps highlight the key differences in terms of the steps that need to be carried out in addition
all the previous steps in the article.
ep 1. Create the MPN profile as before. In the MPN profile, SAP QM processing for MPN should be
tivated. The approved manufacturer part list does not need to be maintained as the same functionality
provided by SAP QM module activation. You do not need to set up AMPL if SAP QM is activated. This is
own in Figure 9.

ep 2. Assign the SAP QM Control Key to the inventory managed part. The key controls how the
ventory managed part is inspected upon receipt. The SAP QM Control Key is set up as shown in Figure
and is associated with the inventory managed part (Material 544) in Figure 10 in the SAP QM view of
e Material.
Figure 10 QM Control Key assigned to inventory managed part (Material 544)
ep 3. Set up the MPN and create a quality information record (QIR) for it. Figure 11 shows how a QIR
created. The QIR is set up for an MPN, manufacturer and vendor. The QIR will then define whether thePN, manufacturer, and vendor are active or blocked. When a source (an MPN) has to be assigned to a
quisition in transaction ME57 this MPN will be proposed as a valid source at the time of processing of a
quisition.

ow that I have described the various scenarios and steps in setting up a manufacturer part number, I
ll walk you through a procure-to-pay scenario with the manufacturer part number activation so that
ou can see MPN in action.
rst, you need to make sure that you have completed the configuration of MPN as described in scenario
and that you have set up the vendor, manufacturer, MPN, inventory part number, and PIR.
Configuration of MPN is completed as described in scenario 4 above
Vendor, Manufacturer, MPN, inventory part number, and PIR have already been set up
ep 1. The purchase requisition has been created for the inventory managed part (Figure 12). These
quisitions can be created manually or automatically through material requirements planning (MRP).
Figure 12 Purchase requisition created for the inventory managed part
ep 2. Maintain the source list for the inventory managed part with the manufacturer part number. Theurce list is a list of approved vendors and the MPNs they are providing. If 1 is entered into the M (MRP
dicator) column, MRP will automatically select this record (e.g., MNFR_C as the manufacturer and 199
the vendor (Figure 13). A fixed vendor can be used as a default source of supply when assigning
urchase requisitions through MRP.

ep 3. Assign the source to the purchase requisition. Use transaction ME57 to assign the source to the
urchase requisition. The purchase requisition number is provided as an input and upon clicking the
ssign Automatically tab, valid sources defined in the previous step will be proposed (MPN Material)
igure 14).

ep 6. Perform a goods receipt (transaction MIGO) against the purchase order. The order quantity, plant,
orage location are defaulted from the purchase order and the goods receipt is posted to Quality
spection automatically (Figure 18).
Figure 18 Goods receipt performed against the MPN and is stamped on the inspection lot
ep 7. Upon goods receipt an inspection lot is created automatically with the manufacturing part number
igure 19).

ep 8. Record usage decision for the inspection lot. The usage decision for an inspection lot confirms
at an inspection has been completed. A usage decision of Accepted or Rejected can be manually
corded indicating whether the lot can be used. Figure 20 shows that the inspection lot is approved for
age (Usage decision).
