Automatically generate SSCC-18 numbers for packages in delivery orders in Odoo

We’ve added a new feature that automatically generates GS1-compliant SSCC-18 numbers for packages in delivery orders. SSCC-18 stands for “Serial Shipping Container Code”; it is an 18-digit GS1 identifier used to uniquely identify a logistic unit, such as a pallet or container.

This feature allows companies to automatically generate and assign unique SSCC-18 numbers to packages on delivery orders (pickings) where the destination is a customer. This automation removes the need for manual entry and ensures compliance with GS1 standards for shipping container codes, which are often required for EDI transactions.

Key Features:

• Customer-Specific Setting
  • On each parent-level contact form, you can enable auto-generating SSCC-18 numbers for each specific customer.

• Auto Generation logic
  • Numbers are constructed dynamically using, Extension digit, GS1 prefix, calculated serial number, and a check digit.

• Unique by Customer
  • Each customer gets a unique sequence, and numbers can be reused after completing a full cycle.

• No Wastage
  • If delivery validation fails, the number is retained and reused for retries—no unnecessary number consumption.

• EDI Support
  • The SSCC-18 numbers integrate seamlessly into existing EDI workflows and are transmitted in ASNs as before.

How It Works:

The system auto-generates numbers based on:

• Application Identifier (AI): The AI “00” indicates the SSCC-18 data structure that will follow.

• Extensin Sigit: The Extension Digit has no defined logic and is used to increase the capacity of the Serial Reference

• GS1 Company Prefix: GS1 Company Prefixes are 7-10 digits. Serial Reference Numbers are 6-9 digits.

• Serial Reference: The Serial Reference number is assigned by the holder of the GS1 Company Prefix to identify a shipping container (logistic unit) uniquely. A Serial Reference cannot be reused for a minimum of 12 months. The combined length of the GS1 Company Prefix and Serial Reference is always 16 digits.

• Check Digit: Calculated using the Modulo 10 algorithm.

How To Set Up

1. In the inventory app, go to Configuration > Settings > Operations and enable “Print UCC-128 shipping labels.”
2. Enter your company’s GS1 company prefix and save once enabled.

1. On a card of the customer you want to generate SSCC-18 numbers for, go to the “Misc” section under the “SO & PO” tab
2. Enable “Print UCC-128 Shipping Label”
3. Select a Default UCC-128 shipping label template
4. Enter the number of labels you want to auto-print.

• SSCC-18 numbers will be auto-generated and assigned to “packages” linked to a delivery upon validation of the delivery.
• No number will be generated if a delivery does not have packages.
