Hi, the logic is perfect, but it doesn't work with Odoo 16.

Can you try it in Odoo 16?

Thanks!

Thanks mate, but the origin field is not the same, here is the correct code:

return_id = record.origin
if return_id:
returns = model.search([('origin', '=', return_id)])
if len(returns) > 1:
raise UserError('There is already a return for this transfer')

Thanks.!!!

Thanks for pointing that out! I appreciate the correction with the origin field.
The code I had may have been an older version, but it worked for me.
Your updated snippet makes sense,Thanks for sharing the insight!

Hi, is working perfect but if i try to make partial orders, when it creates the backorder, triggers the action, because Odoo creates the backorder with the same origin document id.

How can we adapt the code to validate if the origin contains the string "Return of"? whit that, the automated action will only triggers when applies to a return order.

thanks.

Never mind, updated the code as follows:

return_id = record.origin
if "Return of" in return_id:
returns = model.search([('origin', '=', return_id)])
if len(returns) > 1:
raise UserError('There is already a return for this transfer.')
