Hi,

Steps:

1. Settings->Technical->Actions->Server Action

2. Model: Transfer

Type: Execute Code

code:

for rec in records:

  if rec['state'] not in ('done', 'cancel'):

    rec.button_validate()

Hope it helps.

To create a Server Action in Odoo 15 for validating multiple Delivery Orders, follow these steps:

  Navigate to Settings > Technical > Actions > Server Actions.

  Create a new Server Action with the model set to "Stock Picking".

  In the Python Code section, use:
    for picking in records:
      if picking.state not in ('done', 'cancel'):
        picking.button_validate()

  Save the action and link it to the appropriate menu or button.
