Hello,


We are dealing with Odoo Enterprise v14 rental module, and we need to duplicate a sale.order but keeping the same lot ids as in the original one and just modify rental period for a larger period.


The reason is that in many scenarios rental orders need to be extended, whilst preserving the original quotation by tax reasons, therefore we have to create a copy, modify rental dates and return each item from original quotation to pick up again in the new one and this process can be time consuming for larger orders.


By default odoo sets these fields to copy=False, tried to override with
        _inherit = 'sale.order.line'        reserved_lot_ids = fields.Many2many('stock.production.lot', 'rental_reserved_lot_rel', domain="[('product_id','=',product_id)]", copy=True)        pickedup_lot_ids = fields.Many2many('stock.production.lot', 'rental_pickedup_lot_rel', domain="[('product_id','=',product_id)]", copy=True)        returned_lot_ids = fields.Many2many('stock.production.lot', 'rental_returned_lot_rel', domain="[('product_id','=',product_id)]", copy=True)

But this is not working, tried to override sale.order.line copy method and not working either, is there any workaround?


Thanks and regards,
Ramon
