Serial Number Naming
Each item's serial number is a unique value that is assigned to each unit. The item's warranty, AMC, and expiration details can be tracked with the use of the serial number. Machines, computers, and expensive equipment are examples of high-value items that are typically serialised.
Go to the Item master and select the Has Serial No option to serialise an item.
ERPNext offers two methods for generating the Serial No.
1. Serializing Purchase Items
You can use the same serial numbers in ERPNext if the OEM (Original Equipment Manufacturer) has already applied them to the purchased items. Each item's serial number can be scanned or manually entered when creating a purchase receipt.
Serial numbers will be generated automatically in the backend based on the serial numbers you supplied upon submitting the purchase receipt.
Avoid setting a serial number prefix in the item master if you're using OEM serial numbers. The Serial Number Series field ought to be left empty in this instance.
You can enter the serial number in the purchase receipt by simply scanning the barcode if the items you received already have one. [To find out more about barcode scanning, click here].
1.1 Serial numbers are automatically generated in stock transactions
ERPNext has the ability to automatically generate serial numbers for items that lack predefined ones. This occurs during stock transactions like:
Receipt of Purchase
Stock entry (manufacturing or material receipt)
To make this possible:
Verify the item's serial number in the item master.
Enter a format such as PC-2025- in the Serial Number Series field.
ERPNext will produce serial numbers such as:
PC-2025-.00001 PC-2025-.00002 PC-2025-.00003
Serial numbers will be generated automatically in the system upon submission of the purchase receipt or stock entry for the serialised item.
2. Serializing Manufacturing Items
You can specify a Serial Number Series directly in the Item master to serialise an item that is manufactured internally.
Go to: Stock → Item
Open the item
Verify that it has a serial number
Enter a unique naming series in the space provided: Serial Number Series (e.g., MF-ITEM-.#####,)
Once set up, when a Stock Entry (Manufacture) is submitted as part of the production process, ERPNext will automatically generate Serial Numbers based on this series.
2.1 Serial Number and Series
ERPOnce you have indicated that an item is serialised (by ticking the Has Serial No checkbox), you can then specify its Serial No. Series.
This series will be used to automatically create the item's serial number in stock operations, i.e., manufacturing stock entry or purchase receipts.
Assume that the Serial No. Series is designated as MF-ITEM-.#####
The system will generate serial numbers as follows.
MF-ITEM-.00001
MF-ITEM-.00002
MF-ITEM-.00003
This maintains uniform naming and enables easy tracking of units manufactured.
2.2 Production Entry for Serialized Item
If a Stock Entry (Manufacture) is entered for a serialised item, ERPNext will automatically create serial numbers according to the series entered in the item master.
Workflow:
Create a work order
Submit a Stock Entry → Manufacturing
system will create the same number of Serial Nos. as produced quantity.
