2. INTRODUCTION
• The SAP serial number functionality allows managing serialized stock keeping.
• SAP Serial number Management is mainly focuses on Inventory tracking before and after sales.
• It is a precise approach than Batch management. Batches are defined as subset of material in stock.
Serial number is a number that you give to individual item of material in addition to the material
number, in order to differentiate between this individual piece and all other items of the material.
• Serial numbers are assigned apart from the material number in SAP MM to differentiate between
individual pieces and other material items.
• The combination of a material number and a serial number is always unique.

3. INTRODUCTION
The SAP serial number component contributes in following business area:-
• 1. Inventory management
• 2. Production orders
• 3. Repetitive manufacturing
• 4. Quality Management
• 5. Sales orders
• 6. Plant Maintenance

4. SERIALIZED INVENTORY
• Serialized inventory involves tracking individual units using unique serial numbers.
• Serial numbers allow precise identification of specific items or parts within a larger inventory.
• Unlike SKU (Stock Keeping Unit) numbers, which identify the type of product, serial numbers provide
granularity down to individual pieces.
• Serial numbers profile defines the conditions and operations for assigning serial numbers to materials. It
is plant level definition in material master work scheduling view.
SKU Numbers Identify the type of Product while Serial Numbers identify one Specific item or a part of
an item.

5. EQUIPMENT CATEGORY
• Equipment categories are used to categorize equipment based on broad criteria, such as we have used
it as Electrical Equipment, Mechanical Equipment, Instrumentation Equipment, PRT (Production
Resources Tool), Vehicles also some category where material Serial Number functionality is used.
• Material serial number functionality can be used for specific equipment categories.
• You can maintain your own number range for serial profile numbers.
Note:
• The Numbers will be triggered based on the Equipment Category assigned to the Serial Number Profile.
• If you want to maintain your own number range, then create the Number range (either
Internal/External and assigned to the Equipment category)

6. PROCESS FLOW
1. Create the Serial Number Profile:
• Use Transaction Code OSI2 to define the rules and characteristics associated with serial numbers for specific
materials.
• Specify parameters such as whether serial numbers are required and the length of serial numbers.
2. Material Master and Serial Number Profile:
• In the Material Master, assign the previously created serial number profile to the material.
• This ensures that whenever this material is used, the system prompts for serial numbers.
3. Create Serial Numbers:
• Use Transaction Code IQ01 to create individual serial numbers.
• Associate these serial numbers with specific units of the material.

7. PROCESS FLOW
4. Purchase Order Creation (ME21N):
• When creating a purchase order, ensure that the material requires serial numbers.
• Assign the relevant serial numbers to the items in the PO.
5. Goods Movement (GR) in MIGO (Movement Type 101):
• Perform a goods receipt (GR) using Transaction Code MIGO.
• Select movement type 101 (Goods Receipt for Purchase Order).
• Input the serial numbers received along with the goods.

8. CONFIGURATION STEPS
1. Create Serial Number Profile:
• Use SPRO → IMG → Material Management → Purchasing → Serial Numbers → Determine Serial Number
Profiles.
• Create the serial number profile by copying the standard one or adding new entries.
2. Number Ranges for Equipment Category:
• Define number ranges for equipment categories using Transaction Code OIEN.
• Assign the number range to the equipment category.
3. Creation of Serial Number Profile:
• Use SPRO → IMG → Material Management → Purchasing → Serial Numbers → Determine Serial Number
Profiles.
• Create the serial number profile by copying the standard one or adding new entries.

9. CONFIGURATION PATH FOR EQUIPMENT CATEGORY:
SPRO –> IMG –> Plant Maintenance and Customer Service –> Master Data in Plant Maintenance and Customer
Service –> Technical Objects –>Equipment –> Equipment Categories –> Maintain Equipment Category(OIET)

10. CONFIGURATION PATH FOR EQUIPMENT CATEGORY:
• If you want to create the new Equipment category, click on the new entries or else copy from the
standard one.

11. NUMBER RANGES FOR EQUIPMENT CATEGORY:
• SPRO –> IMG –> Plant Maintenance and Customer Service –> Master Data in Plant Maintenance and
Customer Service –> Technical Objects –>Equipment –> Equipment Categories –> Define Number
Ranges
• Transaction Code: OIEN

12. NUMBER RANGES FOR EQUIPMENT CATEGORY:
• Click on change group and if you want to maintain your own Number Range to for Serial Profile Number
Create a number range for and assign the number range to Equipment category.

13. CREATION OF SERIAL NUMBER PROFILE:
• Configuration: SPRO –> IMG – Material Management –> Purchasing –> Serial Numbers –>
Determine Serial Number Profiles

14. IMPORTANT FIELDS MAINTAIN IN SERIAL NUMBER PROFILE:
• Serial Number Existence Requirement indicates that determines whether the serial numbers entered for a
business transaction need to be created first as a Master Record in the system.
• If the indicator is set, the serial numbers must be created before creating Material Master in the system.
• If this indicator is not set, the serial numbers are created during the business Transaction.

15. IMPORTANT FIELDS MAINTAIN IN SERIAL NUMBER PROFILE:
• Stock check for Serial Numbers states whether the system should perform a stock check during serial
number assignment. If it should, it also establishes with what type of notification (Warning or Error)
the system reacts in the event of stock inconsistencies with Inventory Management.

16. SERIALIZING PROCEDURES:
1. It is a four-digit identification code which describes a serialization Procedure. Define on the business
requirement you can set different scenarios for a serial number profile.
2. Select the line item of the serial number profile and click on the Serializing Procedure.
3. MMSL and POSL Procedure is the standard one from MM side.
4. SerUsage (Serial Number Usage) :
• Indicator that determines for a business Transaction, Whether
• No Serial Numbers are assigned.
• Serial Numbers can be assigned.
• Serial Numbers must be assigned.
• Serial Numbers are assigned automatically.

18. EQREQ (EQUIPMENT REQUIREMENT)
• Entry that determines whether or not an equipment master record should be created for each number
when assigned Serial Numbers.
• Use:
1. If you choose the indicator “Default: Without Equipment”, the user can later decide when assigning serial
numbers in the dialog box, whether an equipment master record still be created.
2. If you choose the indicator “With Equipment” this is binding for the user. The indicator cannot be reset.

19. CENTRAL CONTROL PARAMETERS FOR SERIAL
NUMBERS:
• Configuration: SPRO –> IMG –> Material Management
–> Purchasing –> Serial Numbers –> Central Control
Parameters for Serial Numbers
• Transaction Code: OIS1

20. KEY POINT'S FOR YOUR INFORMATION:
1. Once assigned serial number to stock, it's not possible to change. You need to reverse
the goods movement and do it again.
2. You cannot directly change the serial numbers for the existing stocks.
3. Advantage of serial no is, we can track the movements of each serial number of
material.
4. Dis-advantage is, every time you need to enter the serial number for every one quantity
for movements.

21. KEY POINT'S FOR YOUR INFORMATION:
• Serial number can be generated by two options for specific material:
1) Creation of serial number while creating master data.
2) Creation of serial number while doing transactions..
So serial number will not be assigned to old or existing records which are created before serial
number activation.
Once serial number is activated for material, then serial number will be generated while creating
master data or while doing transactions as per settings.
• Note:
1. It is applicable for all modules including PS, Sales Etc.
2. If serial number is required for existing records we need to reverse and post it again

22. CONCLUSION
Managing serial numbers in SAP MM ensures accurate tracking and management of individual
pieces within your inventory.
