Welcome to the next tutorial of SAP PM course! In this tutorial, you will learn about SAP Serial Numbers and their use for serializing equipment in plant maintenance. We will show how to create serial number profile, assign it in a material master record, and create a new serial number attached to equipment.
SAP serial numbers functionality helps managing serialized stock. It is mainly focused on tracking of inventory. Serial number is the number which is assigned apart from the material number in SAP MM in order to differentiate between individual pieces and other material items. The combination of a material number and a serial number is always unique. The SAP serial numbers are used in following areas:
Serializing a piece of equipment enables the equipment to be managed from inventory prospective. When a serial number is assigned to equipment, the equipment is linked with a material and serial number meaning that you can use material serial number to manage the equipment from plant maintenance perspective.
To serialize the equipment, a serial number profile must be configured in customization of plant maintenance.
Define SAP Serial Number Profile
SAP serial number profile is a 4-digits number under which defines the conditions of operation for the assignment of serial numbers to equipment. It is configured in the following menu node of SPRO transaction:
Plant Maintenance and Customer Service > Master Data in Plant Maintenance and Customer Service > Technical Objects > Serial Number Management > Define Serial Number Profiles
In SAP serial number profile, you define 4-digits profile number with a corresponding description. Also, there are the following parameters:
- Serial Number Existence Requirement Indicator: This indicator determines serial number entered for transaction needs to be created first as master record. If you set this indicator, then the serial number must be created as a master record first in the system. If not, then the serial number directly can be created during business transaction.
- Equipment Category: Equipment category according to their use. The equipment category which the system should propose for the automatic assignment of serial numbers in the case of equipment master records.
- Stock Check for Serial Numbers: This indicator determines if stock check during serial number assignment needs to be performed or not.
Assign SAP Serial Number Profile to Material Master Record
SAP serial number profile has to be assigned to each material master to be serialized. You can assign separate serial number profile to material for each plant because assignment of SAP serial numbers profiles to materials is done at the plant level in material master record.
Navigate to the following path in SAP Easy Access menu or start the transaction MM02 directly:
Logistics > Material Management > Material Master > Material > change > Immediately MM02
The following screen will appear where you enter MM02 transaction. Enter the material number and click Select Views button.
Choose Plant data/storage 2 and press Enter.
On change material screen, enter the serial number profile which you have configured in the customization.
Click on Save and SAP serial number profile will be assigned to the material master record.
Create SAP Serial Numbers
SAP serial numbers can be created with a length of 18 characters and support both numeric and alphabetical characters. Serial numbers can be created manually or automatically. Serial number master record can be created prior to the business transaction. If need to create an individual serial number, you can use the transaction IQ01 and if you need to create several SAP serial numbers together use IQ04 transaction.
The following information is contained in SAP serial number master:
- Status information: System status provides you with the information about the current status of SAP serial number. You can also configure a custom status as user status for more information and control over SAP serial numbers.
- Stock information: It provides the information about plant and storage location of material/equipment.
- Serial number history: It provides the past information about serial number master.
To create SAP serial number, follow these steps. Navigate to the following node in SAP Easy Access menu:
Logistics > Plant Maintenance > Management of technical objects > Serial Numbers > IQ01 – Create
On the initial screen of IQ01 transaction, enter following details:
|Material Number||<Material Number>|
|Serial Number||Enter serial number if you have one. If you don’t have one, the system will assign one.|
|Category||< Equipment category>|
Press Enter to continue.
You can enter SAP serial number specific data and click on Equipment view to create an equipment view.
Enter the data related to the equipment and click on Save icon. SAP serial number including the equipment view will be created.
