Serial Number Management in
Subcontract Purchase Orders and
Purchase Requisitions UseYou can enter serial numbers for components (if subcontracting type 1 and 2) for
subcontracting purchase orders and purchase requisitions (purchasing documents).
Serial number management for purchase orders and purchase requisitions is based on the
existing serial number management functions. For more information, see the SAP Library,
under Logistics → LO Logistics - General→ Logistics Basic Data (LO-MD) → Serial Number
Management (LO-MD-SN).
Prerequisites● In the General Plant Data/Storage 2 view of the material master, you must have
assigned the serial number profile to the material.
● You have created a serial number profile and assigned the following procedures to it:
○ For purchase orders, procedure POSL
○ For purchase requisitions, procedure PRSL
If you are using the pre-Enjoy purchasing transactions, you do this in Customizing
for Serial Number Management under Plant Maintenance and Customer
Service → Master Data in Plant Maintenance and Customer Service → Technical
Objects → Serial Number Management → Define Serial Number Profiles.
If you are using the Enjoy purchasing transactions, you do this in Customizing
for Materials Management→ Purchasing → Purchasing Documents → Purchase
Order or Purchase Requisition → Define Document Types.
If you make settings using the Enjoy purchasing transactions, they override
any settings made for a particular serial number profile in the pre-Enjoy
transactions.
For the Enjoy transactions you must additionally have:
○ Selected a document type (for example, a standard purchase order) with an item
category used for subcontracting.
○ Set the serial number usage for the serial number profile in the Maintenance View
Serial Numbers in Purchasing Documents.
Features● In the purchase order, you maintain serial numbers on the Delivery Schedule tab
page.In the purchase requisition, you maintain serial numbers on the Material Data tab
page. For both, you choose Assign Serial Numbers.
● For batch-managed materials, you cannot maintain serial numbers without maintaining
the batch at component level.
● For a recursive repair, where the same physical part is returned by the subcontractor
with unchanged material and serial numbers (subcontracting type = Refurbishment with
Unchanged Material Number), the serial number linked to the purchase order item is the
same for the part provided to the subcontractor (component) and for the receiving part
(item). An unplanned serial number change is possible during goods receipt if the
subcontractor returns a completely different part.
● For a planned modification, where the same physical part is returned by the
subcontractor with a changed material number (subcontracting type = Refurbishment
with Changed Material Number), the serial number linked to the purchasing document
item is the same for the part provided to the subcontractor (component) and for the
receiving part (item). An unplanned serial number change is possible during goods
receipt if the subcontractor returns a completely different part.
● If you have already entered the serial number in a PM/CS order, the serial numbers are
copied to the purchase requisition from the object list of the PM/CS order. You can also
enter the serial number manually. If you make a change to the PM/CS order and the
object list differs from the purchase requisition object list, the system displays a pop up
and you can decide if you want the updated serial numbers to be taken over to the
purchase requisition. For more information, see MRO Subcontracting in Outbound
Deliveries.
● The actual status of the serial number regulates usability of specific serial numbers in
purchasing documents. The serial number can be assigned to the purchasing document
item if the following conditions are fulfilled:
○ Purchasing document is not blocked, deleted, or canceled (EKPO-LOEKZ)
○ Purchase order contains only one schedule line
○ Delivery completed indicator is not set
○ Purchase order item has item category Subcontracting (EKPO-PSTYP = 3).
● Only the first schedule line is considered for serial number assignment.
● The system copies the serial number from the purchase order item to the delivery item
for outbound deliveries, or into material documents which are posted with reference to a
purchase order.
● The number of the serial numbers assigned to the purchasing document item equals the
quantity of the purchasing document item.
● The serial number in the purchasing document item belongs only to the main part to be
repaired, that is the part with material provision indicator (MPI) Rework Material to
Subcontractor. If the provided components (consumables) are also serialized, you can
enter these serial numbers in the follow-on processes for creating the outbound delivery
or posting the transfer posting to the subcontractor.
You can mark a component with this MPI only in the case of a recursive repair,
that is subcontracting types Refurbishment with Unchanged Material
Number or Refurbishment with Changed Material Number.
● During conversion of a planned order into a purchase requisition, it is possible to
transfer serial numbers.
● Once you have entered serial numbers for a purchasing document item, you cannot
change:
○ Item category
○ Subcontracting type
○ Main rework part on component level
If you want to make changes to the subcontract purchasing document for a serialized
component, you have to delete the serial number assignment and change the
purchasing document items.
If you change the purchasing document quantity, you might have to enter additional
serial numbers (increase in purchasing document quantity) or delete existing serial
numbers (decrease in purchasing document quantity).
● You cannot carry out a new BOM explosion if you have already assigned serial numbers
to the main rework material.
