Auto-Remove Cancelled Pickings in Odoo Batch Transfers

Ways to Handle Cancelled Pickings in Odoo

Batch Transfers in Odoo make warehouse operations faster by grouping deliveries and processing them together. However, a common issue arises when a picking is cancelled, it often still remains inside the Batch Transfer list, leading to:

Confusion for warehouse staff
Incorrect processing of cancelled pickings
Extra manual cleanup work

In this blog, we’ll show you two ways to remove cancelled pickings from Batch Transfers in Odoo automatically:

Using a Python customisation (for developers)
Using an Automated Action (no code needed)

Method 1: Python Customisation

For development-focused projects, you can extend the stock.picking model to unlink pickings from batch transfers when cancelled automatically.

Example Code

# -*- coding: utf-8 -*-
from odoo import models
class StockPicking(models.Model):
    _inherit = 'stock.picking'
    def action_cancel(self):
        """
        Inherit cancel action to remove
        cancelled pickings from batch transfers
        """
        res = super(StockPicking, self).action_cancel()
        for picking in self:
            if picking.batch_id:
                # unlink picking from batch transfer
                batch.write({'batch_id': False})
                # optional: log activity
                picking.message_post(
                    body=f"Picking {picking.name} removed 
                         from Batch {batch.name} after cancellation."
                )
        return res

How It Works

Inherit action_cancel() → Runs when a picking is cancelled.
Check for batch_id → If the picking belongs to a batch, it’s identified.
Unlink picking from batch → Set Batch record blank.
Log activity (optional) → Adds a note in chatter for transparency.

Method 2: Automated Action

(No Code Required)

If you prefer a configuration-only approach, Odoo’s Automated Actions can handle this automatically.

Steps to Configure

1. Navigate to:

Settings → Technical → Automation → Automated Actions

2. Create a New Automated Action

Model: Transfer (stock.picking)
Trigger: State is set to → Cancelled
Apply On: Add domain → Status = Cancelled
Action To Do: Update Record → Set Batch Transfer field to blank

Odoo Automated Action configuration to remove cancelled pickings from Batch Transfers

Example Configuration

As shown in the screenshot:

Trigger: When a transfer’s state changes to Cancelled
Condition: Apply only if Status = Cancelled
Action: Update the Batch Transfer field to empty

This way, the cancelled picking is automatically unlinked from its batch.

Which Method Should You Use?

Automated Action (Simple, No Code)

Best for quick setups
Works well if you just need to clear the Batch Transfer field

Python Customisation (Flexible, Advanced)

Better for complex workflows
Allows chatter logging, extra validations, or other custom rules
